Description

Bei Maschinen zum Zerschneiden einer laufenden Papierbahn in einzelne Längsstreifen machte sich bisher der Ubelstand bemerkbar, daß beim Reißen eines Papierstreifens dieser sich zwischen die Schneidmesser . klemmte. Gegenstand der Erfindung ist eine Vorrichtung, die diesen Übelstand beseitigen soll. Die neue Vorrichtung kennzeichnet sich dadurch, daß vor den Schneidmessern ein Geblase o. dgl. angebracht ist, das einen'Luftstrom durch die Messer treibt. Infolgedessen werden nach dem Schneiden gerissene Papierstreifen von den Messern abgetrieben, so daß sie sich nicht mehr zwischen diesen festklemmen. Außerdem können die gerissenen Streifen leicht vom Bedienungspersonal erfaßt und wieder angeknüpft werden, was besondersIn machines for cutting a running paper web into individual longitudinal strips So far the problem has become noticeable that when a strip of paper is torn it between the cutting blades. stuck. The invention relates to a device which should eliminate this evil. The new device is characterized by that in front of the cutting knives a blower o drives through the knife. As a result, strips of paper are torn after cutting driven off the knives so that they no longer get stuck between them. In addition, the torn strips can easily be grasped by the operator and be reconnected, something special

■ beim Disysystem von . großem Vorteil ist.■ with the disysystem of. great advantage is.

Weitere Vorteile der neuen Anordnung bestehen darin, daß die Messer infolge des durchziehenden Luftstromes gekühlt werden und die Papierbahn durch Abblasen des Staubes gereinigt wird.Further advantages of the new arrangement are that the knife as a result of the pulling through Air flow are cooled and the paper web cleaned by blowing off the dust will.

Die neue Vorrichtung ist in der Zeichnung dargestellt.The new device is shown in the drawing.

Die Papierbahn 1 wird von der Rolle 2 abgewickelt und gelangt über die Walzen 3 und 4 zu den Schneidmessern 5, durch die die Papierbahn 1 in einzelne Längsstreifen zerschnitten wird. Die geschnittenen Papierstreifen werden auf; der Rolle 6 wieder aufgewickelt. Vor den Schneidmessern ist die Mündung 7 einer Gebläseleitung angebracht, durch welche während des Papierschneidens ein Luftstrom zwischen die Messer 5 und auf die Papierbahn geblasen wird.The paper web 1 is unwound from the roll 2 and passes over the rollers 3 and 4 to the cutting knives 5, through which the paper web 1 into individual longitudinal strips is cut up. The cut paper strips are on; the roll 6 wound up again. The mouth 7 of a blower line is attached in front of the cutting blades, through which an air flow between the knife 5 and on during the paper cutting the paper web is blown.

Hinter den Messern ist eine Leiste 8 angebracht, die an der den Messern zugekehrten Innenseite mit einem Klebstoff überzogen ist. , Der durch den Luftstrom von der Papierbahn abgeblasene Staub wird gegen die Leiste 8 geschleudert und infolge des Klebstoffes an dieser festgehalten.A bar 8 is attached behind the knives, the one facing the knives Inside is coated with an adhesive. , By the airflow from the Dust blown off the paper web is thrown against the bar 8 and as a result of the adhesive held on to this.

Statt durch eine Gebläse kann der Luftstrom auch durch eine Saugvorrichtung erzeugt werden. In diesem-Falle wird der Staub zugleich abgesaugt.Instead of a fan, the air flow can also be generated by a suction device will. In this case, the dust is extracted at the same time.
