Description

Ble'=lr,üc@urigezi@t@ti@h: aüfhin Verfahren `zur Herstellung von Ventilbeuteln, deren* Einfüllkanal durch einen Ventilschlauch verlängert ist. Es sind schon verschiedentlich Vgrschl@ge -gemacht worden über das Bilden und Einlegen' eipes Veritilschläuches während der, Herstellung des Ventilbodens des Ventil- beuteis. ' Hierbei fnuß darauf geachtet werden, daß :beim, Bilden des Ventilbodens die Seitenklappen des Bodens nicht zwischen den zu bildenden Ventil- schlauch zu liegen kommen. Bei den bekannten Ver- fahren zur Herstellung von Ventilbeuteln, die mit einem Einfüllkanal durch einen Ventilschlauch ver- sehen sind, sind deshalb besondere zusätzliche Falz- vorrichtungen und Falzvorgänge;,erfoz-derlich, bevor das Umlegen der beiden Seitenklappen des Bodens durchgeführt werden kann. Die der Erfindung zugmnde liegende Aufgabe besteht darin, ein Verfahrewzü .schaffen, welches es gestattet, einen Ventilbeutel mit einem verlängerten und außen verschließbaren Ventilschlauch zu schaffen, wobei ohne zusätzliche Falzarbeit und ohne zusätz- liche Falzeinrichtungen beim Urplegen _-,cler-- Seiten- klappen des Bodens die Ventilschläucheinlägeselbst= tätig mitgebildet wird, wobei aber trotzdem das mle en der Seitenklappen des Bodens die Bildung `-eiUne#'"inen"freien"Tüer''sch-niffaufweisenden Ventil- Schlauches nicht gestört wird. Ble '= lr, üc @ urigezi @ t @ ti @ h: also method `for Manufacture of valve bags, their * filling channel is extended by a valve hose. There are Vgrschl @ has already been made on various occasions about the formation and insertion of a veritable tube during the manufacture of the valve base of the valve loot. 'Care must be taken to ensure that : when, forming the valve base, the side flaps of the Bottom not to be formed between the valve hose come to rest. In the well-known drive to the production of valve bags that come with a filling channel through a valve hose are seen, therefore, special additional folds devices and folding processes;, required before folding down the two side flaps of the floor can be carried out. The object underlying the invention consists in creating a process which it Allowed a valve bag with an extended and to create externally closable valve hose, whereby without additional hemming work and without additional lich folding devices for the Urplegen _-, cler-- side- fold the bottom of the valve hose inserts themselves = is actively trained, but still the mle en the side flaps of the bottom the formation `-eiUne # '" inen "free"Tüer''sch-niff-showing valve- Hose is not disturbed.

Dementsprechend besteht das Verfahren, nach. der Erfindung darin, daß die zum Bilden des Ventilschlauches eingelegte Einlage, die zuerst umiulegende Seitenklappe des Bodens seitlich überragend, im -Ab'sfänd- vön etwa_Bödenbreite mit der zuerst umzulegenden Seitenklappe umgefalzt wird, während der zweite Umschlag der Ventilschlaucheinlage, ,dessen Breite gleich oder kleiner ist als der Abstand der zuerst umgefalzten Seitenklappe von der Bodenfalzkante der zuletzt umzulegenden Seitenklappe, durch Umlegen der letztgenanten , Seitenklappe gebildet wird. :. . . . .Accordingly, there is the procedure according to. of the invention in that the insert inserted to form the valve tube is the one that is folded over first Side flap of the floor protruding laterally, in the -Ab'sfänd- vön about_ floor width with the side flap to be folded down first, while the second envelope the valve tube insert, the width of which is equal to or smaller than the distance the first folded side flap from the bottom rebate edge of the last to be folded over Side flap, formed by folding the latter, side flap. :. . . . .

Durch 'diese'Mittel'ües Verfahrens wird es nicht nur erreicht, daß für die Bildung des Ventilschlauches keine zusätzlichen Falzarbeiten erforderlich werden, es können auch keine Differenzen zwischen der Bodenbreite des Beutels und der Ventilschlauchbreite auftreten, wodurch ein sicheres Abdichten in den Falzstellen zwischen der Ventilschlaucheinlage und dem Boden des Ventilbeutels erreicht wird. 1Jie `Einzelheiten des . Verfahren$; Jet, _,Ejftil«"ung gehen aus den in der Zeichnung wiedergegebenen Ausführungsbeispielen des Erfindungsgegenstandes hervor; und zwar zeigen 5 Abb. i; 2, 3 und 4 das Ende des mit einem Ventil- schlauch auszurüstenden Beutels in verschiedenen Zwischenstufen seiner Herstellung, Abb. 5, 6, 7 und 8 die für den Ventilschlauch be- nötigte Einlage ebenfalls in den verschiedenen Zwischenstufen der Falzung, Abb.9, io, ii und 12 ein weiteres Ausführungs- beispiel eines Beutels mit durch Einschnitte verlän- gerte Seitenklappen. In Abb,,i der Zeichnung ist der Sackschlauch i mit dem vorgefälzten Boden 2 veranschaulicht, auf dessen Eckeinschlag 3 an der Ventilseite die Einlage 4 geklebt ist. -Die Einlage 4 (s. Abb. 2 und io) überragt die zuerst umzufaltende Seitenklappe 5. Nach dem Umfalzender Seitenklappe 5 reicht die Schnittkante 6 der; Einlage 4 bis an die Bodenfalzkante 7 der zuletzt umzufältenden Seitenklappe 8 (s. Abb. 3 und ii). 'Narr; ea-kegnt,-.,ßaß durch das nachfolgende Um- falzen-dec-@eitenklappe 8 (Abb. 4 und 1,2) der Boden 9 hergestellt und gleichzeitig der Ventilschlauch io gebildet wird ohne daß die Seitenklappen 5 und 8 zwischen d'en` Venfi)~sc%fäücii iö ge`scäilef"`si"nT @'@"@"` Auf die zu verbindenden Bodenteile und auf die Einlage 4 ,wird vor dem Umfalzen in an sich bekannter Weise Klebstoff aufgetragen. By 'this'Mittel'ües method it is not only achieved that no additional folding work is required for the formation of the valve tube, there can also be no differences between the bottom width of the bag and the valve tube width, whereby a secure seal in the folds between the Valve tube insert and the bottom of the valve bag is reached. 1Jie `details of the. Method $; Jet, _, Ejftil «" ung go from those shown in the drawing Embodiments of the subject matter of the invention forth; namely show 5 Fig. I; 2, 3 and 4 the end of the valve hose to be equipped in different bags Intermediate stages of its manufacture, Fig. 5, 6, 7 and 8 which are used for the valve hose required deposit also in the various Intermediate stages of folding, Fig.9, io, ii and 12 another embodiment example of a bag with incisions extended whipped side flaps. In Fig ,, i of the drawing, the bag tube i illustrated with the pre-rebated floor 2 on the corner entry 3 of which on the valve side is the insert 4 is glued. -The insert 4 (see Fig. 2 and io) protrudes the side flap to be folded over first 5. After the The cut edge 6 extends over the folded side flap 5 the; Insert 4 up to the bottom fold 7 of the last side flap 8 to be folded over (see Fig. 3 and ii). 'Fool; ea-kegnt, -., ßaß through the following um- rebate-dec- @ side flap 8 (Fig. 4 and 1, 2) the bottom 9 manufactured and at the same time the valve hose OK is formed without the side flaps 5 and 8 between d'en` Venfi) ~ sc% fäücii iö ge`scäilef "` si "nT @ '@" @ "` On the floor parts to be connected and on the Insert 4 is known per se before folding over Wise glue applied.
