Description

Papier, das versponnen werden soll, muß erst in schmale Streifen zerschnitten werden. Zu diesem Zwecke läßt ^man* die Papierbahn zwischen zwei Messern hindurchlaufen oder zerschneidet die Papierrolle in einzelne schmale Papierrollen, von denen man dann abspinnt. Je schmäler diese Streifen werden, um so größer werden die Schwierigkeiten, gleichmäßig geschnittene Streifen ohne Abfall zu erhalten.Paper that is to be spun must first be cut into narrow strips. For this purpose the paper web is left Run between two knives or cut the paper roll into individual narrow ones Rolls of paper from which one then spins off. The narrower these strips become, the more so the difficulty of obtaining uniformly cut strips without waste increases.

Nach der Erfindung können die schmälsten Streifen dadurch glatt aus der Papierbahn geschnitten werden, daß die Papierbahn an der Schnittstelle zwangläufig regelbar gespannt gehalten wird.According to the invention, the narrowest strips can thereby be cut smoothly from the paper web be that the paper web is inevitably kept tensioned in an adjustable manner at the interface.

In der Zeichnung ist ein Ausführungsbeispiel einer solchen Vorrichtung dargestellt.In the drawing, an embodiment of such a device is shown.

Die in Richtung des Pfeiles laufende Papierbahn f wird in bekannter Weise zwischen Führungswalzen d, e durch die Messer a in Streifen zerschnitten. Zur Spannung des Papiers erhält gemäß der Erfindung die Walze e eine regelbare Voreilung. Außerdem läuft zur Erzielung eines glatten Schnittes die Papierbahn f an der gespannten Schnittstelle über eine anT sich bekannte Nutenleiste b, die die gespannte Papierbahn den Messern entgegenhält, und die nach der Erfindung zwecks Erhöhung der Spannung in Höhe verstellbar eingerichtet J ist. The paper web f running in the direction of the arrow is cut into strips by the knives a in a known manner between guide rollers d, e. According to the invention, the roller e is provided with an adjustable advance for tensioning the paper. In addition, in order to achieve a smooth cut, the paper web f runs at the tensioned interface over a grooved strip b known per se, which holds the tensioned paper web against the knives and which, according to the invention, is adjustable in height to increase the tension.

Sollte ein geschnittener Streifen reißen, dann führeri_sich die Enden selbsttätig der Rolle e zu.Should a cut strip tear, then the ends automatically guide themselves to the roll e .
