Description

Maschine zum Quertrennen von Papierbahnen Die Erfindung betrifft eine Maschine zum Quertrennen von Papierbahnen und ist insbesondere dazu bestimmt, Papierbogen zur Herstellung von Papierbeuteln zu erzeugen. Es sind Maschinen bekannt, die in der Papierbahn eine quergerichtete Schwächungslinie anbringen und durch eine einem Zugwalzenpaar vorgeschaltete Reißvorrichtung die Papierbahn in einzelne Blätter trennen lassen.Machine for the transverse severing of paper webs The invention relates to a Machine for the transverse cutting of paper webs and is especially designed to cut paper sheets to produce paper bags. There are known machines that are used in attach a transverse line of weakness to the paper web and through a one Pull roller pair upstream tearing device cuts the paper web into individual sheets let separate.

Die Erfindung stellt sich die Aufgabe, gegeneinander gestaffelte oder treppenförmig versetzte Trennkanten in einer mehrfachen Papierbahn anzubringen. Die auf diese Weise hergestellten Blätter werden insbesondere in nicht Gegenstand der Erfindung bildender Weise zu Papierschläuchen verarbeitet, bei denen die Längsfaser des Papiers mit der Längsrichtung des Schlauches zusammenfällt.The invention has the task of staggered or staggered against each other to attach step-like staggered separating edges in a multiple paper web. In particular, the sheets produced in this way do not become an object the invention forming way processed into paper tubes in which the longitudinal fiber of the paper coincides with the length of the tube.

Gemäß der Erfindung durchläuft jede Einzelpapierbahn je eine Perforationseinrichtung, z. B. ein Perforationszylinderpaar, und diese Perforationszylinderpaare sind gegenüber dem gemeinsamen Zugwalzenpaar derart angeordnet, daß die Schwächungsstellen in festgelegter Versetzung nacheinander die Griffstelle der Zugwalzen durchlaufen. Die dann durch die Reißvorrichtung an den gestaffelten Trennkanten abgerissenen Papierblätter können dann ohne weiters zu Papierschläuchen mit gestaffelt übereinandergreifender Längsklebenaht verarbeitet werden.According to the invention, each individual paper web runs through a perforation device, z. B. a pair of perforation cylinders, and these pairs of perforation cylinders are opposite the common pair of pulling rollers arranged in such a way that the weakening points in fixed Move through the grip point of the pull rollers one after the other. Then through the tear device at the staggered separating edges of torn paper sheets then without further ado to paper tubes with staggered, overlapping longitudinal glued seams are processed.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, und zwar zeigt Abb. 1 eine Seitenansicht und Abb. 2 eine Draufsicht auf die perforierte Papierbahn und eine nach dem neuen Verfahren abgetrennte Papierlage.An embodiment of the invention is shown in the drawing, namely Fig. 1 shows a side view and Fig. 2 shows a plan view of the perforated Paper web and a paper layer separated according to the new process.

Die von einer Mehrzahl von Vorratsrollen 1, 2, 3 kommenden Papierbahnen 1', 2', 3' werden durch Perforationszylinderpaare 4, 5 ; 6, 7 und 8, g geführt und mit Perforationslinien 1", 2", 3" versehen. Von hier werden die Papierbahnen über Leitwalzen 1o und 11 zwischen Zugwalzen 12 und 13 zusammengeführt, und zwar in Wegen von solcher Länge, daß sich die von den Walzenpaaren 4, 5 usw. angebrachten Schwächungsstellen 1", 2", 3" in der aus Abb. 2 erkennbaren Weise staffelartig oder treppenartig verschoben anordnen. Von den Zugwalzen aus werden die Papierbahnen Reißwalzen 17 und 18 zugeführt, bei welchen die obere Walze 18 in einem Hebelpaar 14 und 15 gelagert ist und durch Exzenter 16 auf und ab bewegt wird. Diese Reißwalzen 17 und 18 besitzen eine größere Umfangsgeschwindigkeit als die Zugwalzen 12 und 13, wodurch beim Auftreffen der Oberwalze 18 auf die untere Walze 17 die Differenz in der Umfangsgeschwindigkeit der beiden Walzenpaare 12, 13 und 17,18 sich auf die mehrfache Papierbahn auswirkt, die an ihren Perforations- oder Schwächungslinien 1", 2", 3" auseinandergerissen wird.The paper webs coming from a plurality of supply rolls 1, 2, 3 1 ', 2', 3 'are through perforation cylinder pairs 4, 5; 6, 7 and 8, g led and provided with perforation lines 1 ", 2", 3 ". From here the paper webs are over Guide rollers 1o and 11 merged between draw rollers 12 and 13, namely in ways of such a length that the weakening points made by the pairs of rollers 4, 5, etc. 1 ", 2", 3 "shifted in the manner shown in Fig. 2 in a staggered or stair-like manner arrange. The paper webs are fed from the pull rollers to tear rollers 17 and 18, in which the upper roller 18 is mounted in a pair of levers 14 and 15 and through Eccentric 16 is moved up and down. These tear rollers 17 and 18 have a larger one Peripheral speed than the pulling rollers 12 and 13, whereby when they hit the Upper roller 18 on the lower roller 17 the difference in the peripheral speed of the two roller pairs 12, 13 and 17, 18 affects the multiple paper web, which are torn apart at their perforation or weakening lines 1 ", 2", 3 " will.

Statt der Reißwalzen können andere mit größerer Geschwindigkeit arbeitende Vorrichtungen, wie Zangen o. dgl., Anwendung finden.Instead of the tear rollers, others can work at greater speeds Devices such as pliers o. The like. Find application.
