Description
Gegenstand der Erfindung ist ein Verfahren und die zu seiner Ausübung benötigte Vorrichtung zum Schneiden vorher gummierter Papier- o. dgl. Bahnen, die von einer Rolle abgezogen werden. Dieses Verfahren kennzeichnet sich dadurch, daß das Schneiden in dem Augenblick beginnt, in dem der Vorschub sein Ende erreicht, wobei das Lösen des Vorschubgreifers von der Papierbahn vorgenommen wird, ehe das Schneiden beendet ist, so daß die Papierbahn nicht zurückgezogen werden kann, wenn sich diese am Greifer angeklebt hat. Die Vorrichtung zur Ausübung des Verfahrens kennzeichnet sich durch eine zweckentsprechende Verbindung des Vorschubantriebes und des Schneidmesserantriebes, so daß die erfindungsgemäß gestellte Forderung erfüllt wird, daß das Schneiden unmittelbar vor Beendigung des Vorschubes beginnt, und daß der Greifer von der Papierbahn gelöst wird, ehe das Schneiden beendet ist.The subject matter of the invention is a method and the method required to carry it out Device for cutting previously gummed paper o. The like. Web from a Can be withdrawn from the roll. This method is characterized in that the cutting begins at the moment when the feed comes to an end, with the loosening of the feed gripper is made by the paper web before the cutting is finished so that the paper web cannot be withdrawn if it has stuck to the gripper. The device for Execution of the procedure is characterized by an appropriate connection of the feed drive and the cutting knife drive, so that the inventively provided Requirement is met that the cutting begins immediately before the end of the feed, and that the gripper of the paper web is released before the cutting is finished.
Das Abschneiden kurzer Stücke von irgendwelchen gummierten Papierbahnen erfolgte bisher maschinell im Trockenzustand des Klebstoffes, nachdem das Material vorgeschoben war. War die Papierbahn mit einem feuchten Klebstoff bzw. mit einem sogenannten Dauerklebstotif versehen, so klebte bei den bekannten Vorrichtungen die Papierbahn während des Abschneideiis an der Vorschubeinrichtung an und wurde dann mit dieser zurückgezogen, wodurch Störungen unvermeidlich waren. Durch den Erfindungsgegenstand werden diese Nachteile behoben. Es geht die Vorschubeinrichtung in ihre Ausgangsstellung zurück, während das Messer mit der Papierbahn in Eingriff ist, also die Papierbahn von dem Messerpaar gehalten wird. Dadurch kann die Vorschubeinrichtung die Papierbahn nicht mit zurückziehen, selbst dann nicht, wenn ein Anhaften der Papierbahn an der Vorschubeinrichtung während des vorher erfolgten Vorschubes eingetreten war.Short pieces of any gummed paper webs were cut off previously by machine in the dry state of the adhesive after the material had been advanced was. If the paper web was provided with a moist adhesive or with a so-called permanent adhesive, it stuck in the known devices the paper web during the cutting at the feed device and was then withdrawn with this, whereby interference was inevitable. These disadvantages are eliminated by the subject matter of the invention. The feed device goes back to its starting position while the knife is in engagement with the paper web, that is, the paper web is held by the pair of knives will. As a result, the feed device cannot pull back the paper web at the same time, not even if the paper web adheres to the feed device during of the previous advance had occurred.
