Description

Einrichtung zum Längsreißen von Gewebebahnen Gegenstand der Erfindung ist eine Einrichtung zum Längsreißen von Gewebebahnen mit ortsfest gelagerten Reißwalzen, welche die benachbarten gerissenen Gewebestreifen nach verschiedenen Richtungen abfuhr en.Device for the longitudinal tearing of fabric webs object of the invention is a device for the longitudinal tearing of fabric webs with stationary tearing rollers, which the adjacent torn strips of tissue in different directions departed.

Die bekannten Stoffreißmaschinen, bei welchen mehr als zwei Längsstreifen aus der Stoffbahn ,gerissen werden, bedürfen außer den Reißwerkzeugen zusätzlicher Einrichtungen und Mittel, die eine Stoffbreitenstreckung bewirken. Für Gin sauberes Reißen der Stoffbahn müssen die Reißwerkzeuge ,auf die zwischen ihnen hindurchgeführte Stoffbahn einen Preßdruck ausüben. wodurch bei ungleichen Stoffstärken ein Schlupf unvermeidlich wird. Hierdurch .entstehen an den Reißwerkzeugen ungleiche Reibwiderstände, die ihrerseits ein Verziehen der Stoffbahn im Gefolge haben. Überdies sind die bekannten Stoffreißmaschinen im Aufbau verwickelt und daher kostspielig.The known pulping machines, in which more than two longitudinal strips are torn from the web of material, apart from the tearing tools, additional tools are required Devices and means that cause the fabric to be stretched. For gin clean Tearing the fabric web must be the tearing tools on which passed between them Apply pressure to the fabric. which leads to slippage in the case of unequal fabric thicknesses becomes inevitable. This creates unequal frictional resistance at the ripping tools. which in turn cause the fabric to warp. Moreover, the well-known Debris removal machines involved in construction and therefore costly.

Demgegenüber sind mit der erfindungsgemäßen Einrichtung größere Vorteile erreichbar dadurch, daß am Umfang einer regelbar angetriebenen Stofförderwalze Reißwalzen ,angeordnet sind, deren Durchmesser nur einen Teil des Durchmessers der Förderwalze betragen und die sich auf der Förderwalze .abwälzen.In contrast, there are greater advantages with the device according to the invention achievable in that tearing rollers on the circumference of a controllably driven fabric feed roller , are arranged, the diameter of which is only a part of the diameter of the conveyor roller and which roll on the conveyor roller.

Ein grundsätzliches Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung als Schaubild dargestellt.A basic embodiment of the subject matter of the invention is shown in the drawing as a diagram.

Die zu reißende Gewebebahn i läuft in Richtung des Pfeiles von einer Vorratswalze ab und wird einer Stofförderwalze ? zugeführt, die regelbar angetrieben wird. Die durch Einschneiden in den gewünschten Gewebestreifenbreiten entsprechenden Abständen erhaltenen Streifen- oder Bandanfänge 3, d. und 5 werden zwischen der Förderwalze 2 und den ortsfesten Reißwalzen 6, 7 und 8 hindurchgeführt und gemäß den angedeuteten Pfeilen 9, i o und i i aus der Durchführungsrichtung zum Längsreißen herausgebracht. Die sich auf der Förderwalze 2 abwälzenden Reißwalzen 6, 7 und 8 können innerhalb geringer Grenzen radial zur Förderi;.alze verschiebbar gelagert sein, was für das Reißen verschieden starker Gewebehahnen zweckmäßig ist. Die Förderwalze 2 läuft in der angegebenen Pfeilrichtung um. Die gerissenen Gewebestreifen werden in an sich üblicher Weise von angetriebenen Abzieh- oder Aufwickelvorrichtungen übernommen.The fabric web to be torn i runs in the direction of the arrow from one Is the supply roller off and becomes a material feed roller? fed, which is controllably driven will. The corresponding by cutting into the desired fabric strip widths The beginnings of strips or bands 3 obtained at intervals, d. and 5 are between the Conveyor roller 2 and the stationary tear rollers 6, 7 and 8 passed through and according to the indicated arrows 9, i o and i i from the implementation direction for longitudinal tearing released. The tearing rollers 6, 7 and 8 rolling on the conveyor roller 2 can be mounted within small limits radially to the conveyor roller be what is useful for tearing tissue taps of different strengths. The conveyor roller 2 rotates in the direction indicated by the arrow. The torn strips of fabric will be in a conventional manner by powered take-off or take-up devices accepted.
