Die Erfindung betrifft eine Vorrichtung zum Abschneiden einer Papierbahn mittels eines mit einem elastischen Gegenwerkzeug aus Pappe zusammenarbeitenden Messers, wie sie insbesondere zur Herstellung von Papierservietten, Gesichtstüchern, Taschentüchern und Handtüchern aus Kreppapier, Tüchern, Unterlagen, Toilettenpapier u. dgl. verwendet wird.The invention relates to a device for cutting a paper web by means of a with a elastic counter-tool made of cardboard cooperating knife, such as those used in particular for the production of paper napkins, facial tissues, handkerchiefs and towels made of crepe paper, handkerchiefs, Documents, toilet paper, etc. is used.

Es ist bekannt, eine solche Papierbahn dadurch abzuschneiden, daß sie zwischen zwei Walzen vorgeschoben wird, von denen die eine mit einem in der Axialrichtung angebrachten Messer versehen ist, das gegen die andere Walze, die Gegenwalze, welche mit Nuten versehen ist, gedrückt wird und hierbei die dazwischenliegende Papierbahn abschneidet. Diese bekannten Vorrichtungen besitzen jedoch den Nachteil, daß das Messer verhältnismäßig schnell abgenutzt wird und ausgetauscht oder geschliffen werden muß, was eine teure Betriebsunterbrechung bedeutet.It is known to cut off such a paper web by feeding it between two rollers one of which is provided with a knife attached in the axial direction, the against the other roller, the counter roller, which is provided with grooves, is pressed and this is the cuts the paper web in between. However, these known devices have the disadvantage that the knife is worn out relatively quickly and replaced or sharpened must, which means an expensive business interruption.

Weiterhin ist es bekannt, Papierbahnen mittels Messer zu schneiden, wobei die Papierbahnen auf einer elastischen Führung aus Pappe aufliegen.It is also known to cut paper webs by means of a knife, the paper webs on rest on an elastic guide made of cardboard.

Von diesem Stand der Technik ausgehend, liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum Abschneiden einer Papierbahn zu schaffen, bei welcher der Verschleiß des Messers wesentlich herabgesetzt wird.Proceeding from this prior art, the invention is based on the object of a device to create for cutting a paper web, in which the wear of the knife is significant is reduced.

Gemäß der Erfindung wird dies dadurch erreicht, daß das mit dem auf einer Walze axial angebrachten Messer zusammenarbeitende, walzenförmig ausgebildete Gegenwerkzeug aus auf einer gemeinsamen Welle aufgezogenen nutfreien Pappe- oder Papierrondellen besteht, deren zylindrische Umfangsfläche den Mantel der Gegenwalze bildet.According to the invention this is achieved in that the axially mounted with the on a roller Knife cooperating, roller-shaped counter tool from on a common Shaft raised, groove-free cardboard or paper washers, the cylindrical peripheral surface of which forms the mantle of the counter roll.

Durch diese Ausbildung der Gegenwalze wird erreicht, daß der Verschleiß des Messers auf ein Minimum herabgesetzt wird.This design of the counter roll ensures that the wear of the knife is reduced to a minimum is reduced.

Gemäß einem weiteren Merkmal der Erfindung sind die Messerwalze und die Gegenwalze hinsichtlich ihrer Drehlage gegeneinander verstellbar, so daß die Benutzung der gesamten Oberfläche als elastisches Gegenwerkzeug für das Messer möglich ist.According to a further feature of the invention, the knife roller and the counter roller are with respect to their rotational position against each other adjustable, so that the use of the entire surface as elastic Counter tool for the knife is possible.

Die Papierbahn wird zwischen dieser Messerwalze 6 und einer Gegenwalze 5 eingeführt, die gemäß den obigen Ausführungen aus einer großen Anzahl hart aneinander gepreßten und auf einer gemeinsamen drehbaren Welle 5ß aufgezogenen Pappen- oder Papierrondellen hergestellt ist. Diese bilden eine ausreichend harte und etwas elastische Fläche für die Gegenwalze, so daß der Verschleiß des Messers 11 und der Prägeglieder 11 and with embossing members 12 , which emboss the paper web in the desired pattern and thereby also stitch the paper layers together, if the web consists of several layers. The paper web is introduced between this knife roller 6 and a counter roller 5 which, according to the above statements, is made from a large number of cardboard or paper discs that are pressed hard against one another and drawn onto a common rotatable shaft 5b. These form a sufficiently hard and somewhat elastic surface for the counter roller, so that the wear of the knife 11 and the embossing members

Zweckmäßig erfolgt jedoch das Abschneiden nicht vollständig, sondern es werden einige nicht beschnittene kleinere Teile im Schnitt dadurch freigelassen, daß die Messerschneide mit entsprechenden Ausnehmungen versehen wird, so daß die aufgeschnittene Bahn nach Verlassen der Messerwalze immer noch zusammengehalten wird.Appropriately, however, the trimming is not carried out completely, but rather some are not trimmed Smaller parts are left free in the cut, that the knife edge with corresponding recesses is provided so that the cut web is still after leaving the knife roller is held together.

trennt werden. Sie werden zu einem anderen Transportglied 10 geleitet, um gestapelt oder verpackt zu werden. Das Messer 11 kann nach einer gewissen Betriebszeit so tiefe Eindrücke in der Oberfläche der Gegen- walze 5 zurücklassen, daß das Abschneiden nicht mehr genügend scharf ausgeführt werden kann. Daher ist es zweckmäßig, daß die gegenseitige Drehlage der Walzen 5 und 6 nach einer gewissen Betriebszeit verstellt wird, so daß das Messer auf eine andere Fläche der Gegenwalze als vorher auftrifft. Nachdem der gesamte Umkreis der Gegenwalze auf diese Weise verbraucht worden ist, kann die Fläche der Gegenwalze erneut glatt geschliffen werden. Patentansprüche:be separated. They are directed to another transport link 10 to be stacked or packaged. After a certain operating time, the knife 11 can leave behind such deep impressions in the surface of the counter-roller 5 that the cutting can no longer be carried out sufficiently sharply. It is therefore useful that the mutual rotational position of the rollers 5 and 6 is adjusted after a certain operating time so that the knife hits a different surface of the counter roller than before. After the entire circumference of the counter roll has been used up in this way, the surface of the counter roll can be sanded smooth again. Patent claims: 1.
