Description

Verfahren zum Herstellen eines Ventilsackes aus Papier Es ist bekannt, bei Papiersäcken mit Faltbodenverschluß und Einfüllventil, den Einfüllkanal länger und damit sein Schließen sicherer zu machen.Method for producing a valve bag from paper It is known For paper sacks with a folding bottom closure and filling valve, the filling channel is longer and thus to make its closing more secure.

Die bekannten Ventileinlagen sind in der Regel mit der Innensleite des Einfüllventils verbunden und ragen entweder mit einem Ende aus dem Einfüllventil nach außen, um den .gefüllten Sack von außen abschließen zu können, oder sie ragen mit einem Ende über den normalen inneren Ventilrand hinaus in das Innere des Sackes, um den .gefüllten Sack durch den Druck der Füllmasse gegen Einfüllventil und Einlage. selbsttätig abzuschließen.The known valve inserts are usually connected to the inside of the filling valve and either protrude with one end out of the filling valve in order to be able to close the filled sack from the outside, or they protrude with one end beyond the normal inner valve edge into the Inside of the sack, around the filled sack due to the pressure of the filling compound against the filling valve and insert . to complete automatically.

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen. eines an sich bekannten Ventilsackes aus Papier. Dabei wird eine Einlage in. den noch offenen Ventilboden .eingelegt. Erfindungsgemäß wird das zum Bilden des. Ventilschlauches. eingelegte Papierstück vor dem Abschneiden von der Rolle und vor dem Einlegen in den Boden an jener Seite umgefalzt, an der die zuletzt umzulegende Seitenklappe des Bodens liegt. Nach einer anderen Ausführung känn das eingelegte Papierstück ernst nach dem Einkleben in den Boden unigefalzt werden. Hierdurch wind erreicht, daß die nach ihrer Yertigstellung schl.auchföxmige Einlage in bekannter Weise ein in sich geschlossenes Schlauchstück bildet, ohne daß Seitenklappen des Bodens dazwischengeschaltet sind. In der Zeichnung isst ein Ausführungsbeispiel der Erfindung veranschaulicht. Es zeigen Abb. i den Sackschlauch mit dem vorgefalzten Ventilboden, Abb. a den fertiggefalztep Ventilboden ohne die schlauchfärrnige Einlage, Abb.3 den vomgefalzten Ventilboden mit eingelegtem Schlauchstück g vom oben gesehen.The invention relates to a method of manufacture. one known valve sack made of paper. A deposit is made in the still open valve base. According to the invention, this is used to form the valve tube. loaded piece of paper before cutting it from the roll and loading it into the bottom folded over on the side on which the last side flap to be folded down of the ground. According to another embodiment, the inserted piece of paper can Seriously unfolded after gluing into the bottom. Through this wind reached that the insert, which is closed after its completion, is included in a known manner forms a self-contained piece of tubing without interposed side flaps of the bottom are. An exemplary embodiment of the invention is illustrated in the drawing. Fig. I shows the bag tube with the pre-folded valve base, Fig. A the fully folded p Valve bottom without the tubular insert, Fig. 3 the folded valve bottom with inserted hose section g seen from above.

Abb. q.stellt :eine Seitenansicht dar bei leicht geöffnetem Ventil. -Abb. 5 ist eine Schnittzeichnung durch das Ventil des fertigen Sackes.Fig. Q. Shows: a side view with the valve slightly open. - Fig. Figure 5 is a cross-sectional view through the valve of the finished sack.

Abb. 6, 7 und 8 veranschaulichen die besondere Art des Verfahrens.Fig. 6, 7 and 8 illustrate the special nature of the process.

In Abb.3 der Zeichnung ist die Anordnung der fertigen t.schlauchfärmigen Einlage g veranschaulicht; sie bildet ein in sich geschlossenes Schlauchstück, welches mit seinem Ende m ,an .einer umgeschlagenen Ecke b des vo.rgefalzten Ventilb.o,dens angeklebt isst. Es ist ersichtlich, daß beim Umfalzen der beiden Seitenkl.appen h und i um die Falzkanten c, , d und e, f die Außenseite des Endes m: mit der Innenseite des ventilbildenden Eckeinschlages b verbunden wird, wenn ein Klebstoffauftragen an: den entsprechenden Verbindungslsbellen vorher erfolgt ist. Das andere Ende des Schlauchstückes g ragt frei beweglich in das Innere des Sackes, so daß beim Füllen des Sackes der Füllstutzen der Füllmaschine durch das Ventil und durch das darin angeordnete schlauchförmige Stück ä geführt werden kann.In Fig.3 of the drawing the arrangement of the finished tubular insert g is illustrated; it forms a self-contained piece of hose, which is glued with its end m to a folded corner b of the pre-folded valve b.o, dens. It can be seen that during folding over of the two Seitenkl.appen h and i c to the folded edges, d and e, f, the outer side of the end m: is connected b with the inside of the valve-forming Eckeinschlages when an adhesive applying to: the corresponding Verbindungslsbellen was done beforehand. The other end of the hose piece g projects freely movable in the interior of the bag, so that filling of the bag be in the filling of the filling machine can be led through the valve and the like through the tubular disposed therein piece.

Diese Anordnung des Schlauchstückes g hat den Vorteil, daß zwischen den Falt- und Klebekanten aller ventilbildenden Teile keine Austrittswege für das Füllgut offen bleiben und außerdem die gesamte Ventileinrichtung beweglicher bleibt, weil sie in keiner Weise mit den Seitenklappen verklebt ist: Das Bildern und Einlegen des Schlauchstücken g wird während der Herstellung des Ventilbodens auf verschiedene Art und Weise ermöglicht.This arrangement of the hose piece g has the advantage that between the folded and glued edges of all valve-forming parts no exit routes for the The product remains open and the entire valve device remains more mobile, because it is in no way glued to the side flaps: the pictures and insertion of the hose piece g is different during the manufacture of the valve base Way enables.

Eis kann das schlauchförmige Stück g dadurch gebildet werden, daß von einer Papierrolle eine ,entsprechend breite Papierbahn abrollt, zugeführt und .ein Stück k entsprechend lang ,abgeschnitten in den halbfertigen Ventilboden des Sackes eingelegt und geklebt wird. Vom Papierstück h wird in der Maschine vor dem Abschneiden eine Seite L umgefalzt (Abb.7), so. daß bei der Weiterbildung des Bodens dann das schlauchförmige Stück g gebildet wird, wobei zu beachten ist, daß die Seitenklappe lt zuerst umgefalzt wird. Es ist natürlich möglich, die umgefalzte Seite L' auf die Seite der Seitenklappe, lt zu legen> so daß dann sinngemäß die Seitenklappe i zuerst umgelegt werden ruß.Ice, the tubular piece g can be formed in that a paper roll of corresponding width rolls off a paper roll, is fed in, and a piece k of corresponding length is cut into the semi-finished valve bottom of the sack and glued. One side L of the piece of paper h is folded over in the machine before cutting (Fig.7), see above. that the tubular piece g is then formed in the further development of the bottom, whereby it should be noted that the side flap lt is folded over first. It is of course possible to put the folded side L ' on the side of the side flap, lt> so that the side flap i is then folded over first.

Ferner besteht die Möglichkeit, das Stückh in seiner ganzen zum Bilden des schlauchfö!ranigen Stückes ä erforderlichen Breite in dein hälbfextigen Boden zu legen und an den ,erforderlichen Stellen festzukleben. Beim Weitergleiten des Sackes in der B:odenfalz-@m,aschine wird dann durch eine Falzvorrichtung die Seite l umgelegt, bevor das Umlegen der beiden Seitenklappen lt und z in ;der beschrieb:enen Art erfolgt.There is also the possibility of forming the piece in its entirety of the tubular piece of the required width into your half-textured bottom to lay and to glue at the required places. When sliding the Sack in the B: odenfalz- @ m, aschine is then the page through a folding device l folded down before folding down the two side flaps lt and z in; which described: enen Kind takes place.

Endlich ist es möglich, anstatt die zum Bilden des Schlauchstückes g @erforderlichen Papierstücke h von einer Rolle abzuschneiden, dieselben als vorher geschnittene Einzelblätteir zuzuführen.Finally it is possible instead of the one to form the hose piece g @ cut off the necessary pieces of paper h from a roll, the same as before to feed cut single sheets of paper.
