Definitions
- Felting needles and their manufacturing processes are known. Felting needles change the density of confused textile fibers. In most cases, the fibers are compacted into felted sheets. For this purpose, felting needles are suspended on a suspension (often called a "foot"), often simply in a bent part of their shank, in a needle board. Felting needles are often elongated needles, apart from their suspension, which often terminate at their work-sharing end (the end of the needle facing the fibers) in a point.
- a suspension often called a "foot”
- Felting needles are often elongated needles, apart from their suspension, which often terminate at their work-sharing end (the end of the needle facing the fibers) in a point.
- This working part usually has a specially shaped cross-sectional area (very often polygonal shapes, such as triangular or rectangular shapes are used). However, round shapes - such as drop shapes - are known for such cross-sectional areas.
- notches which extend from the outer profile of the cross-sectional surface of the working part in the direction of the interior thereof. The production of these notches is often done by grooving. The piercing of notches in felting needles is inter alia by the documents US 3,224,067 B and US 2,495,926 B shown.
- the needle boards perform a large number of work cycles per unit time during felt production. It is therefore not surprising that felted needles are exposed to high stress in particular by the contact with the textile fibers. Increasing the durability or service life of felting needles is therefore one of the topics that experts have been working on for a long time.
- the publication US 2,678,484 B proposes to solve this problem, Felt needles, which are provided with a plurality of successive in the longitudinal direction of the needle notches, to provide with a needle tip closest notch, which is less pronounced and also has a less pronounced puncture bead than that of the Top further offending notches.
- the present invention is based on the object of increasing the service life of felting needles.
- the present invention proceeds from the latter document and solves the problem in each case by the feature combination of claims 1 and 8.
- most felting needles have a working part with a cross-sectional area which extends in the radial direction (r) and the circumferential direction ( ⁇ ) of the felting needle and is limited by a cross-sectional profile in a large part of the longitudinal extent of the working part.
- a large part of the longitudinal extent of the working part is called here in the rule that the Working part deviates only in the border regions to the shaft of the needle and or the working end of the needle (usually the tip) and in the region of the notches and notch beads.
- This is advantageous because the working part of the felting needles is to be immersed in the fibers, with mainly the notches and possibly the notch grooves to take the fibers. Accordingly, it is then mainly or exclusively the notches and possibly the notch grooves which break through the cross-sectional profile of the working part or deviate from it.
- At least one notch engages in the cross-sectional profile in the working part.
- the notch is in this case formed by a recess which extends from the cross-sectional profile in the direction of the interior of the felting needle - or on the needle axis. It could also be said that the notches of felting needles generally run from the outer contour of the cross-sectional profile in the radial and axial directions to the inner and optionally to the symmetry axis of the felting needles.
- the at least one bulge can already be provided during the production of the working part. However, it can advantageously also come about through a subsequent manufacturing process. It only protrudes in one Part of the extension of the working part in the longitudinal direction of the felt needle in the radial direction beyond the cross-sectional profile addition. Thus, the bulge is just not part of the cross-sectional profile, which is indeed constant over a large part of or even the entire working part. The bulge is also not a bridge or a rib in the sense of US 3,224,067 B because these components of the needle also run over the entire working part.
- the bulge has at least volume components which are not attributable to the puncturing bead, that is, which did not come about as a result of the volume displacement of the groove for producing the notch.
- the bulge is reinforced by the puncture bead, which is beneficial.
- the notch in the longitudinal direction of the felting needles adjoins the outer surface of the bulge. This is what the notch can do by being in the advancing direction of the needle when felting before the bulge or after the bulge. If the bulge is made in front of the notch, it is advantageous to pierce the notch either immediately prior to the start of the bulge or even into the bulge so that the notch directly adjoins the (possibly new) outer surface of the bulge, but on the other side of the notch remain no remnants of the bulge. You could also say that the notch can take advantage of the original outer surface of the bulge in an advantageous manner.
- notch and bulge are also possible.
- the notch and the bulge have the same position in the circumferential direction and / or they lie on a web.
- the already mentioned radial direction (r) of the needle is often called "height direction”. It is advantageous if the at least one bulge has a height that changes in the direction of the longitudinal extension of the needle. For example, it is advantageous if the bulge in the plane, which is spanned by the longitudinal extent and the radial direction of the needle, a convex profile (from the point of view of the axis of symmetry of the needle). Even a square profile can bring benefits. In both cases, it is advantageous if the height of the bulge has local maxima. It is advantageous because the maximum of the height of the bulge is at least 25%, more preferably at least 30% of the total longitudinal extension of the bulge away from the turning point of the notch.
- the bulge by a non-machining process - such as a pressing process - or at least to make part of the preparation of the bulge with such a process. It is advantageous if the pressing tools or at least one pressing tool are moved at least predominantly in the circumferential direction and / or the radial direction of the needle. However, the at least one bulge can already come about through the molding process, which produces the cross-sectional profile of the working part, or already in the production of the blank.
- the first notch is located on that side of a first bulge which faces the needle point in the longitudinal direction of the needle. But there are also needles - so-called inverted notch needles or U needles - in which the notches are advantageously along the longitudinal direction (z) of the needle on the side facing away from the needle tip.
- the bulge already exists (for example, already in the blank of the needle) or is formed before the notch is inserted. It is further advantageous to position the notch in such a way that when the notch is pierced the puncturing blade also displaces partial areas of the bulge, or in this way increases the thickness of the bulge in the radial and / or circumferential direction of the needle (it forms again a puncture bulge in the area of the bulge that reinforces it). This effect can occur when the chisel is placed in the immediate vicinity of the bulge or even on the bulge itself.
- the at least one bulge is located at a location of the needle surface at which the edge of the cross-sectional profile of the working part is particularly far away from the needle axis. This is the case in the area of the webs or in the area of edges. If this design maxim is heeded, the at least one bulge still projects beyond the already exposed web or the exposed edge so that it comes into very strong contact with fibers in the process of felting.
- the bulge is a pressed sausage, it is advantageous to produce it with at least two pressing tools.
- These two pressing tools act - at least predominantly - in the circumferential direction of the needle.
- the effective direction will also contain components in the radial direction of the needle.
- the effective direction of the two pressing tools is opposite, it being possible to move both tools by the same amount or by different amounts.
- a tool can only serve as a stop while the other or the others are moved.
- the bulge is provided with a clearly defined boundary surface in the radial direction of the needle.
- This shaping the boundary surface in the radial direction of the needle can go to a defined setting the height of the bulge.
- This measure is thus advantageous in all embodiments of the disclosed and claimed in this document needles.
- the molding can be performed with a stamp acting at least predominantly in the radial direction of the needle. At least predominantly acting in the radial direction stamp is again that the working surface of the punch acts mainly in the radial direction.
- the punch can be moved predominantly in the radial direction. However, it can also serve as a stop, which avoids the further growth of the bulge in the radial direction.
- such a stop acting in the radial direction avoids the further growth of the bulge as a result of a pressing process in which the pressing tools act predominantly in the circumferential direction and thus displace the material of the bulge in the redial direction.
- the acting in the radial direction punch thus serves in this case as a stop for the displaced material of the bulge.
- the stop or punch acting in the radial direction can also be structurally connected (possibly even in one piece) to at least one of the pressing tools, which act predominantly in the radial direction of the needle and can produce the bulge, as far as this is a pressed bead.
- FIG. 1 shows a side view of a felting needle 1 of the prior art with a notch 2 and a notch produced by the groove of the notch 3.
- the notch 2 has a notch depth 5.
- the lower boundary of the notch 2 is the notch bottom 9.
- the notch breast 20 which ends with increasing height (in the radial direction) in the inflection point 18 of the notch breast 20.
- needle 1 has a standard dreikant cross-sectional shape 24, as in FIG. 4 will be shown. Also in the Figures 2 and 3 Felting needles 1 shown have this cross-sectional shape 24. From the viewing plane 17 (see FIG. 4 ) is therefore also the web 6 (such webs are often called chamfer) to recognize.
- the bulge 7 with its maximum height 21 should be mentioned.
- Such a bulge can, as already mentioned, be produced in various ways.
- the stamp imprint 8 can be recognized, which indicates that the bulge 7 shown there has come about through an embossing process. In FIG. 2 no score 2 is shown.

- notch geometry 2 and bulge 7 can be achieved by the notch 2 by a puncture, which penetrates the surface of the existing bulge 7 is produced.
- FIGS. 4 to 9 show by way of example various cross-sectional shapes 24-29 of working parts 15 of felting needles. These sectional shapes or surfaces extend in the plane subtended by the radial direction (r) and the circumferential direction ( ⁇ ) of the respective felt needle 1. These working parts 15 are advantageous, but the application of the present invention is also extendable to other cross-sectional shapes.
- FIG. 4 shows a standard dreikant cross-sectional shape 24 of a working part 15, which is provided with three webs 6.
- the observation level 17 of the Figures 1-3 . 11 and 12 such as 16 and 17 has already been mentioned.
- the FIG. 5 shows the cross-sectional shape of a working part 15, which is often sold under the brand name Cross Star 25 and has four webs 6.
- the cross-sectional shape 26 in FIG. 6 is often called drop form in professional circles.
- cross-sectional shape 27 is often called in professional circles Pinchblade.
- the FIGS. 8 and 9 show a Tristar 28 or EcoStar 29 called cross-sectional shape.
- cross-sectional shapes have in common that they are in the working part 15 of the needle in the extend radial (r) and the circumferential direction ( ⁇ ) and form in a major part of the longitudinal extent of the working part of the same cross-sectional shape. Often only the notches 2 as well as the notch beads 3 and bulges 7 form exceptions in this respect.
- the list of cross-sectional shapes in the present document is exemplary in nature. The present invention is suitable for the advantageous development of all known and future cross-sectional shapes. The same statement applies to different forms of notches.
- FIG. 10 shows a felting needle 1 to illustrate some used in this document terms. Like many felting needles, this one has a foot 10 for attachment to a needle board. After a 90 ° bend begins the shaft 11 of the felting needles, which merges after the upper cone 12 in a reduced shaft 13.
- felting needles are also known, which have only a shaft with a uniform diameter and not a shaft 11 and a reduced shaft 13.
- the lower cone 14 forms the transition to the working part 15, on which notches 2 can be seen.
- the felting needle 1 ends in a point 16.
- patterning needles are also known in which these "tip" 16 or their working end have a different contour than conventional needles.
- the present invention can be used advantageously with any felting needles.
- FIG. 12 shows a common section of the in the Figures 3 and 11 shown needle 1 from the same observer level 17. So are in FIG. 12 two notches 2 and two bulges 7 to see. The aforementioned objects have the same position in the circumferential direction ( ⁇ ). The length 32 of the notch opening in the longitudinal direction (z) of the needle 1 and the distance 33 of the edge of the notch opening to the beginning of the next bulge 7 is also shown. As already mentioned, it is advantageous if these two lengths or distances 32, 33 are in a certain ratio or a certain minimum distance 33 is maintained.
- FIG. 12 indicates a dashed line where the needle axis 34 is inside the needle.
- FIGS. 6 and 8 indicate the position of this needle axis explicitly with the reference numeral 34.
- this position is outlined by a cross.
- Needle axis 34 is the center of the needle lengthwise portion of the needle (In FIG. 10 Shank 11, upper cone 12, reduced shank 13, lower cone 14, working part 15 and possibly tip 15).
- the needle axis 34 is the main axis of symmetry of the needle without foot 10.
- FIGS 16 and 17 show side views of a portion of two needles 1 with further embodiments of bulges 7, which with a specially formed boundary surface 36 of the bulge 7 in the radial direction (r) are provided.
- This shaping of the boundary surface 36 can be made with a radially acting punch 37.
- the double arrow 38 indicates the effective direction of this stamp. In this case, effective direction does not necessarily mean that the punch 37 is also moved in this direction (r). On the contrary, it can also act in this direction if it stops relative to the needle 1 and counteracts further growth of the bulge 7 during its creation.
- the described molding of the boundary surface 36 is advantageous in all embodiments of the needle shown.

Description
Filznadeln und ihre Herstellungsverfahren sind bekannt. Mit Filznadeln wird die Dichte wirr liegender Textilfasern verändert. In den meisten Fällen werden die Fasern zu Flächengebilden aus Filz verdichtet. Hierzu werden Filznadeln an einer Aufhängung (oft "Fuß" genannt), die oft einfach in einem gebogenen Teil ihres Schaftes besteht, in einem Nadelbrett aufgehängt. Filznadeln sind von ihrer Aufhängung abgesehen oft lang gestreckte Nadeln, die an ihrem arbeitsteiligen Ende (dem Ende der Nadel, das den Fasern zugewandt ist) oft in einer Spitze auslaufen.Felting needles and their manufacturing processes are known. Felting needles change the density of confused textile fibers. In most cases, the fibers are compacted into felted sheets. For this purpose, felting needles are suspended on a suspension (often called a "foot"), often simply in a bent part of their shank, in a needle board. Felting needles are often elongated needles, apart from their suspension, which often terminate at their work-sharing end (the end of the needle facing the fibers) in a point.
Ein Teil der vorerwähnten Längserstreckung der Nadel wird von dem Arbeitsteil, an das sich oft die Spitze der Nadel anschließt, eingenommen. Dieses Arbeitsteil besitzt in der Regel eine speziell angeformte Querschnittsfläche (sehr oft werden Vieleckformen, wie Dreieck- oder Viereckformen, verwendet). Jedoch sind auch runde Formen - wie Tropfenformen - für solche Querschnittsflächen bekannt. In dem Arbeitsteil befinden sich Kerben, die von dem Außenprofil der Querschnittsfläche des Arbeitsteiles in Richtung auf das Innere desselben verlaufen. Die Herstellung dieser Kerben erfolgt oft durch Einstechen. Das Einstechen von Kerben in Filznadeln wird unter anderem durch die Druckschriften
Die Nadelbretter vollführen bei der Filzherstellung eine große Zahl von Arbeitstakten pro Zeiteinheit. Es ist daher nicht verwunderlich, dass Filznadeln insbesondere durch den Kontakt mit den textilen Fasern einer hohen Belastung ausgesetzt sind. Die Erhöhung der Haltbarkeit bzw. der Standzeiten von Filznadeln gehört daher zu den Themen, die die Fachwelt bereits seit langer Zeit bearbeitet. Die Druckschrift
Der technischen Lehre der ebenfalls bereits erwähnten Druckschrift
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, die Standzeit von Filznadeln zu erhöhen. Hierzu geht die vorliegende Erfindung von der letztgenannten Druckschrift aus und löst die Aufgabe jeweils durch die Merkmalskombination der Ansprüche 1 und 8.The present invention is based on the object of increasing the service life of felting needles. For this purpose, the present invention proceeds from the latter document and solves the problem in each case by the feature combination of
Wie bereits angesprochen, besitzen die meisten Filznadeln einen Arbeitsteil mit einer Querschnittsfläche, die sich in der radialen Richtung (r) und der Umfangsrichtung (ϕ) der Filznadel erstreckt und in einem Großteil der Längserstreckung des Arbeitsteiles von einem Querschnittsprofil begrenzt wird. Ein Großteil der Längserstreckung des Arbeitsteiles heißt hierbei in der Regel, dass der Arbeitsteil lediglich in den Grenzbereichen zu dem Schaft der Nadel und oder dem arbeitsseitigen Ende der Nadel (in der Regel der Spitze) und im Bereich der Kerben und Kerbenwülste abweicht. Dies ist von Vorteil, da der Arbeitsteil der Filznadeln in die Fasern eintauchen soll, wobei hauptsächlich die Kerben und gegebenenfalls die Kerbenwülste die Fasern mitnehmen sollen. Dementsprechend sind es dann auch hauptsächlich oder ausschließlich die Kerben und gegebenenfalls die Kerbenwülste, die das Querschnittsprofil des Arbeitsteiles durchbrechen bzw. von ihm abweichen.As already mentioned, most felting needles have a working part with a cross-sectional area which extends in the radial direction (r) and the circumferential direction (φ) of the felting needle and is limited by a cross-sectional profile in a large part of the longitudinal extent of the working part. A large part of the longitudinal extent of the working part is called here in the rule that the Working part deviates only in the border regions to the shaft of the needle and or the working end of the needle (usually the tip) and in the region of the notches and notch beads. This is advantageous because the working part of the felting needles is to be immersed in the fibers, with mainly the notches and possibly the notch grooves to take the fibers. Accordingly, it is then mainly or exclusively the notches and possibly the notch grooves which break through the cross-sectional profile of the working part or deviate from it.
So greift in dem Arbeitsteil zumindest eine Kerbe in das Querschnittsprofil hinein. Die Kerbe ist hierbei von einem Einstich gebildet, der von dem Querschnittsprofil in Richtung auf das Innere der Filznadel - bzw. auf die Nadelachse - verläuft. Man könnte auch sagen, dass die Kerben von Filznadeln in der Regel von der Außenkontur des Querschnittsprofils in radialer und axialer Richtung auf das innere und gegebenenfalls auf die Symmetrieachse der Filznadeln zu laufen.Thus, at least one notch engages in the cross-sectional profile in the working part. The notch is in this case formed by a recess which extends from the cross-sectional profile in the direction of the interior of the felting needle - or on the needle axis. It could also be said that the notches of felting needles generally run from the outer contour of the cross-sectional profile in the radial and axial directions to the inner and optionally to the symmetry axis of the felting needles.
Wie ebenfalls bereits erwähnt besitzen hierbei die meisten Filznadeln Einstichwülste im Bereich der Kerben, die bei dem Einstich durch Materialverdrängung zu Stande gekommen sind. Diese Einstichwülste kragen in der radialen Richtung der Nadel über die vorgenannte Kontur hinaus aus. Damit haben sie einen erheblichen Beitrag zur Filzbildung.As also mentioned above, most felting needles have puncture beads in the region of the notches which have come about during the puncture due to material displacement. These puncture beads project beyond the aforementioned contour in the radial direction of the needle. This makes a significant contribution to felt formation.
Herkömmliche Filznadeln - die in der Regel die vorgenannten Merkmale haben - werden durch die vorliegende Erfindung durch die folgenden Merkmale weitergebildet:
- zumindest eine Ausbuchtung, welche die Umfangsfläche der Filznadel in ihrem Arbeitsteil in Ihrer radialen Richtung (r) überragt,
- wobei sich die Ausbuchtung in Längsrichtung (z) der Filznadel nur über einen Teilbereich der Erstreckung des Arbeitsteils in dieser Richtung (z) erstreckt,
- wobei die Ausbuchtung Volumenbestandteile aufweist, die nicht zur Einstichswulst der Kerbe gehören
- und wobei sich die Kerbe in der Längsrichtung der Filznadel an die Aussenfläche der Ausbuchtung anschließt.
- at least one bulge, which projects beyond the circumferential surface of the felting needle in its working part in its radial direction (r),
- wherein the bulge extends in the longitudinal direction (z) of the felting needle only over a partial region of the extension of the working part in this direction (z),
- wherein the bulge has volume components which do not belong to the groove of the notch
- and wherein the notch in the longitudinal direction of the felting needle adjoins the outer surface of the bulge.
Die zumindest eine Ausbuchtung kann bereits bei der Herstellung des Arbeitsteiles vorgesehen werden. Sie kann jedoch vorteilhafter Weise auch durch einen sich anschließenden Herstellvorgang Zustandekommen. Sie kragt nur in einem Teilbereich der Erstreckung des Arbeitsteils in Längsrichtung der Filznadel in der radialen Richtung über das Querschnittsprofil hinaus. Damit ist die Ausbuchtung eben kein Teil des Querschnittsprofils, das ja über einen großen Teil des oder gar den gesamten Arbeitsteil konstant ist. Die Ausbuchtung ist auch kein Steg oder eine Rippe im Sinne der
Die Ausbuchtung weißt zumindest Volumenbestandteile auf, die nicht der Einstichswulst zuzurechnen sind, d.h., die nicht infolge der Volumenverdrängung des Einstichs zur Herstellung der Kerbe zu Stande gekommen sind. In der Regel wird die Ausbuchtung jedoch durch die Einstichswulst verstärkt, was von Vorteil ist.The bulge has at least volume components which are not attributable to the puncturing bead, that is, which did not come about as a result of the volume displacement of the groove for producing the notch. In general, the bulge is reinforced by the puncture bead, which is beneficial.
Von besonderem Vorteil ist es, wenn sich die Kerbe in der Längsrichtung der Filznadeln an die Außenfläche der Ausbuchtung anschließt. Dies kann die Kerbe tun, indem sie sich in der Vortriebsrichtung der Nadel bei der Filzbildung vor der Ausbuchtung oder nach der Ausbuchtung befindet. Falls die Ausbuchtung vor der Kerbe hergestellt wird, ist es vorteilhaft, die Kerbe entweder unmittelbar vor Beginn der Ausbuchtung einzustechen oder gar so in die Ausbuchtung hineinzustechen, dass sich die Kerbe wieder unmittelbar an die (ggf. neue) Außenfläche der Ausbuchtung anschließt, jedoch auf der anderen Seite der Kerbe keine Überbleibsel der Ausbuchtung verbleiben. Man könnte auch sagen, dass die Kerbe die ursprüngliche Außenfläche der Ausbuchtung in vorteilhafter Weise durchgreifen kann. Möglich ist auch ein geringer Abstand zwischen Kerbe und Ausbuchtung (Beipiele: kleiner als eine Kerbenlänge in Längsrichtung der Nadel (z), vorteilhafterweise kleiner als eine halbe Kerbenlänge in dieser Richtung (z), noch größere Vorteile treten bei einem Abstand auf, der kleiner als ein Viertel der Länge der Kerbenöffnung in Längsrichtung der Nadel ist). Vorteilhafterweise haben die Kerbe und die Ausbuchtung dieselbe Position in Umfangsrichtung und/oder sie liegen auf einem Steg.It is particularly advantageous if the notch in the longitudinal direction of the felting needles adjoins the outer surface of the bulge. This is what the notch can do by being in the advancing direction of the needle when felting before the bulge or after the bulge. If the bulge is made in front of the notch, it is advantageous to pierce the notch either immediately prior to the start of the bulge or even into the bulge so that the notch directly adjoins the (possibly new) outer surface of the bulge, but on the other side of the notch remain no remnants of the bulge. You could also say that the notch can take advantage of the original outer surface of the bulge in an advantageous manner. Also possible is a small distance between notch and bulge (examples: smaller than a notch length in the longitudinal direction of the needle (z), advantageously smaller than half a notch length in this direction (z), even greater advantages occur at a distance which is less than a quarter of the length of the notch opening in the longitudinal direction of the needle is). Advantageously, the notch and the bulge have the same position in the circumferential direction and / or they lie on a web.
Die bereits erwähnte radiale Richtung (r) der Nadel wird oft auch "Höhenrichtung" genannt. Von Vorteil ist, wenn die zumindest eine Ausbuchtung eine Höhe besitzt, die sich in der Richtung der Längserstreckung der Nadel ändert. So ist es zum Beispiel vorteilhaft, wenn die Ausbuchtung in der Ebene, die von der Längserstreckung und der radialen Richtung der Nadel aufgespannt wird, ein konvexes Profil (aus Sicht der Symmetrieachse der Nadel) besitzt. Auch ein eckiges Profil kann Vorteile mit sich bringen. In beiden Fällen ist es von Vorteil, wenn die Höhe der Ausbuchtung lokale Maxima aufweist. Von Vorteil ist es, denn das Maximum der Höhe der Ausbuchtung mindestens 25 %, noch vorteilhafter mindestens 30 % der gesamten Längserstreckung der Ausbuchtung von dem Wendepunkt der Kerbe entfernt ist. Vorteilhaft ist es, die Ausbuchtung durch einen nicht spanenden Bearbeitungsvorgang - wie zum Beispiel einen Pressvorgang - herzustellen oder zumindest einen Teil der Herstellung der Ausbuchtung mit einem solchen Vorgang vorzunehmen. Hierbei ist es von Vorteil, wenn die Presswerkzeuge oder zumindest ein Presswerkzeug zumindest überwiegend in Umfangsrichtung und/oder der radialen Richtung der Nadel bewegt werden. Die zumindest eine Ausbuchtung kann jedoch auch bereits durch den Anformvorgang, der das Querschnittsprofil des Arbeitsteiles herstellt, oder bereits bei der Herstellung des Rohlings zustande kommen.The already mentioned radial direction (r) of the needle is often called "height direction". It is advantageous if the at least one bulge has a height that changes in the direction of the longitudinal extension of the needle. For example, it is advantageous if the bulge in the plane, which is spanned by the longitudinal extent and the radial direction of the needle, a convex profile (from the point of view of the axis of symmetry of the needle). Even a square profile can bring benefits. In both cases, it is advantageous if the height of the bulge has local maxima. It is advantageous because the maximum of the height of the bulge is at least 25%, more preferably at least 30% of the total longitudinal extension of the bulge away from the turning point of the notch. It is advantageous to produce the bulge by a non-machining process - such as a pressing process - or at least to make part of the preparation of the bulge with such a process. It is advantageous if the pressing tools or at least one pressing tool are moved at least predominantly in the circumferential direction and / or the radial direction of the needle. However, the at least one bulge can already come about through the molding process, which produces the cross-sectional profile of the working part, or already in the production of the blank.
Vorteilhaft ist es, wenn sich zumindest Teilbereiche der Ausbuchtung mit zunehmender Höhe (=radialer Abstand von der Nadelachse) derselben verjüngen. Je nach der Art der Anwendung der Filznadeln wird es vorteilhaft sein, wenn sich die erste Kerbe auf derjenigen Seite einer ersten Ausbuchtung befindet, die in Längsrichtung der Nadel der Nadelspitze zugewandt ist. Es gibt aber auch Nadeln - so genannte umgekehrte Kerbennadeln oder U Nadeln - bei der sich die Kerben vorteilhafterweise entlang der Längsrichtung (z) der Nadel an der der Nadelspitze abgewandten Seite befinden.It is advantageous if at least portions of the bulge with increasing height (= radial distance from the needle axis) of the same taper. Depending on the type of application of the felting needles, it will be advantageous if the first notch is located on that side of a first bulge which faces the needle point in the longitudinal direction of the needle. But there are also needles - so-called inverted notch needles or U needles - in which the notches are advantageously along the longitudinal direction (z) of the needle on the side facing away from the needle tip.
Es ist von Vorteil, wenn sich in dieser Richtung (Richtung der ersten Kerbe aus Sicht der ersten Ausbuchtung) in einem gewissen Abstand (beispielsweise gemessen vom Rand der Kerbe aus) keine weitere Ausbuchtung in Längsrichtung der Nadel mehr anschließt. Dies gilt insbesondere für Ausbuchtungen, die sich in Umfangsrichtung (ϕ) mit der Kerbe überschneiden.It is advantageous if in this direction (direction of the first notch from the view of the first bulge) at a certain distance (for example, measured from the edge of the notch), no further bulge in the longitudinal direction of the needle connects more. This applies in particular to bulges that overlap in the circumferential direction (φ) with the notch.
Beispiele für solche vorteilhaften Mindestabstände sind:
- a) zumindest ein Abstand, der dem Einfachen der Länge der Kerbenöffnung in Längsrichtung der Filznadel entspricht,
- b) vorteilhafterweise jedoch ein Abstand, der dem Doppelten der Länge der Kerbenöffnung in Längsrichtung der Filznadel entspricht,
- c) vorteilhafterweise jedoch ein Abstand, der dem Vierfachen der Länge der Kerbenöffnung in Längsrichtung der Filznadel entspricht,
- d) wenn sich überhaupt keine weitere Ausbuchtung in Längsrichtung (z) der Filznadel mehr befindet, die sich in Umfangsrichtung mit der ersten Kerbe überschneidet.
- a) at least one distance which corresponds to the length of the notch opening in the longitudinal direction of the felting needle,
- b) advantageously, however, a distance which corresponds to twice the length of the notch opening in the longitudinal direction of the felting needle,
- c) advantageously, however, a distance which corresponds to four times the length of the notch opening in the longitudinal direction of the felting needle,
- d) if at all no further bulge in the longitudinal direction (z) of the felting needle is more, which overlaps in the circumferential direction with the first notch.
Es ist von Vorteil, wenn die Ausbuchtung bereits vorhanden ist (zum Beispiel bereits im Rohling der Nadel) oder angeformt wird, bevor die Kerbe eingestochen wird. Von weiterem Vorteil ist es, die Kerbe so zu positionieren, dass der Einstichsmeisel beim Einstechen der Kerbe auch Teilbereiche der Ausbuchtung verdrängt, bzw. auf diese Weise die Stärke der Ausbuchtung in der radialen und/oder der Umfangsrichtung der Nadel verstärkt (es bildet sich wieder eine Einstichwulst im Bereich der Ausbuchtung, der diese verstärkt). Dieser Effekt kann Zustande kommen, wenn der Meisel in unmittelbarer Nachbarschaft der Ausbuchtung oder sogar an dieser selber angesetzt wird.It is advantageous if the bulge already exists (for example, already in the blank of the needle) or is formed before the notch is inserted. It is further advantageous to position the notch in such a way that when the notch is pierced the puncturing blade also displaces partial areas of the bulge, or in this way increases the thickness of the bulge in the radial and / or circumferential direction of the needle (it forms again a puncture bulge in the area of the bulge that reinforces it). This effect can occur when the chisel is placed in the immediate vicinity of the bulge or even on the bulge itself.
Es ist vorteilhaft, wenn die zumindest einem Ausbuchtung sich an einer Stelle der Nadeloberfläche befindet, an der der Rand des Querschnittsprofils des Arbeitsteils besonders weit von der Nadelachse entfernt ist. Dies ist im Bereich der Stege oder im Bereich von Kanten der Fall. Wird diese Gestaltungsmaxime beherzigt, so ragt die zumindest eine Ausbuchtung noch über den bereits exponierten Steg oder die exponierte Kante hinaus, so dass sie beim Prozess des Filzens in sehr starken Kontakt mit Fasern kommt.It is advantageous if the at least one bulge is located at a location of the needle surface at which the edge of the cross-sectional profile of the working part is particularly far away from the needle axis. This is the case in the area of the webs or in the area of edges. If this design maxim is heeded, the at least one bulge still projects beyond the already exposed web or the exposed edge so that it comes into very strong contact with fibers in the process of felting.
Wenn und soweit es sich bei der Ausbuchtung um eine Presswurst handelt, ist es vorteilhaft, sie mit zumindest zwei Presswerkzeugen herzustellen. Diese beiden Presswerkzeuge wirken - zumindest vorwiegend - in der Umfangsrichtung der Nadel. In der Regel wird die Wirkrichtung jedoch auch Komponenten in der radialen Richtung der Nadel enthalten. Die Wirkrichtung der beiden Presswerkzeuge ist entgegengesetzt, wobei es möglich ist, beide Werkzeuge um den gleichen Betrag oder um unterschiedliche Beträge zu bewegen. Hierbei kann auch ein Werkzeug lediglich als Anschlag dienen, während das oder die anderen bewegt werden.If and as far as the bulge is a pressed sausage, it is advantageous to produce it with at least two pressing tools. These two pressing tools act - at least predominantly - in the circumferential direction of the needle. In general, however, the effective direction will also contain components in the radial direction of the needle. The effective direction of the two pressing tools is opposite, it being possible to move both tools by the same amount or by different amounts. Here, a tool can only serve as a stop while the other or the others are moved.
Es ist vorteilhaft, wenn die Ausbuchtung mit einer klar definierten Begrenzungsfläche in radialen Richtung der Nadel versehen wird. Dieses Ausformen der Begrenzungsfläche in der radialen Richtung der Nadel kann bis hin zu einem definierten Einstellen der Höhe der Ausbuchtung gehen. Diese Maßnahme ist damit bei allen Ausführungsformen der in dieser Druckschrift offenbarten und beanspruchten Nadeln vorteilhaft. Das Ausformen kann mit einem zumindest vorwiegend in der radialen Richtung der Nadel wirkenden Stempel vorgenommen werden. Zumindest vorwiegend in der radialen Richtung wirkenden Stempel heißt wieder, dass die Arbeitsfläche des Stempels vorwiegend in der radialen Richtung wirkt. Der Stempel kann vorwiegend in der radialen Richtung bewegt werden. Er kann jedoch auch als Anschlag dienen, der das weitere Wachstum der Ausbuchtung in der radialen Richtung vermeidet. Beispiel: ein solcher in der radialen Richtung wirkender Anschlag vermeidet das weitere Wachsen der Ausbuchtung in Folge eines Pressprozesses, bei dem die Presswerkzeuge vorwiegend in Umfangsrichtung wirken und so das Material der Ausbuchtung in redialer Richtung verdrängen. Der in radialer Richtung wirkende Stempel dient damit in diesem Fall als Anschlag für das verdrängte Material der Ausbuchtung. Hierbei kann der in der radialen Richtung wirkende Anschlag oder Stempel auch baulich mit zumindest einem der Presswerkzeuge verbunden sein (gegebenenfalls sogar einstückig), die vorwiegend in der radialen Richtung der Nadel wirken und die Ausbuchtung erzeugen können, soweit diese eine Presswulst ist.It is advantageous if the bulge is provided with a clearly defined boundary surface in the radial direction of the needle. This shaping the boundary surface in the radial direction of the needle can go to a defined setting the height of the bulge. This measure is thus advantageous in all embodiments of the disclosed and claimed in this document needles. The molding can be performed with a stamp acting at least predominantly in the radial direction of the needle. At least predominantly acting in the radial direction stamp is again that the working surface of the punch acts mainly in the radial direction. The punch can be moved predominantly in the radial direction. However, it can also serve as a stop, which avoids the further growth of the bulge in the radial direction. Example: such a stop acting in the radial direction avoids the further growth of the bulge as a result of a pressing process in which the pressing tools act predominantly in the circumferential direction and thus displace the material of the bulge in the redial direction. The acting in the radial direction punch thus serves in this case as a stop for the displaced material of the bulge. In this case, the stop or punch acting in the radial direction can also be structurally connected (possibly even in one piece) to at least one of the pressing tools, which act predominantly in the radial direction of the needle and can produce the bulge, as far as this is a pressed bead.
