Abstract

The cutting knife consists of a knife retainer (1) and a strip knife (2), which are adhered to each other. An adhesive foil (3) is inserted between the two sections, which are then maintained under pressure at a temperature of 80 deg. - 120 deg., for 50-70 minutes. Before insertion of the foil, the retainer and knife are degreased. The arrangement avoids to necessity for mechanical clamps or cam surfaces which are bulky and heavy.

Description

Schneidemesser für Papierschneide- oder dergl. Maschinen Bei den bekannten Papierschneidemaschinen wird das Schneidemesser in üblicher Weise mittels Schraubenverbindung am Messerbalken gehalten. Cutting knife for paper cutting or similar machines known paper cutting machines, the cutting knife is in the usual way by means of Screw connection held on the cutter bar.

Es ist auch bekannt, dae Schneidemesser als sogenanntes Streifenmesser auszubilden, das mit einem Messerträger fest verbunden ist. Der Messerträger wird dann wiederum durch Schraubenverbindung am Messerbalken der Maschine gehalten. It is also known to use the cutting knife as a so-called strip knife train, which is firmly connected to a knife carrier. The knife carrier becomes then again by screw connection on the cutter bar of the machine held.

Die Befestigung des eigentlicllen Schneidemessers am Messerträger kann durch mechanische oder elek-tromagnetische Mittel erfolgen.The attachment of the actual cutting knife to the knife carrier can be done by mechanical or electromagnetic means.

Auch ist es bekannt, Messerträger und Schneidemesser durch eine Wärmebehandlung miteinander zu verbinden.It is also known to heat-treat knife carriers and cutting knives to connect with each other.

Hierbei ist es erforderlich, daß Messerträger und Schneidemesser stark erhitzt werden, um eine sichere Verbindung zu gewährleisten. Aus dem gleichen Grunde müssen Messer und Messerträger aus ähnlichem Material bestehen, um bei der Weiterverarbeitung (Härtung) auftretende Spannungen möglichst gering zu halten und damit Härterisse soweit wie möglich auszuschließen.Here it is necessary that the knife carrier and cutting knife be strong heated to ensure a secure connection. For the same reason Knives and knife carriers must be made of similar material in order to be able to use them for further processing (Hardening) to keep occurring tensions as low as possible and thus hardening cracks to be excluded as far as possible.

Die mechanische Befestigung des Streifenmessers am Messerhalter hat den Nachteil, daß ein Nachstellen oftmals erforderlich wird und daß die Herstellung derartiger Messer verhältnismäßig aufwendig und damit unwirtschaftlich ist.The mechanical attachment of the strip knife to the knife holder has the disadvantage that readjustment is often required and that the production such a knife is relatively expensive and therefore uneconomical.

Auch bei der magnetischen Verbindung zwischen Messerträ--ger und Streifenmesser ist die Verbindung-tecimisch sehr autTendig, so daß auch hier die lvirtschaStlichkeit nicht gegeben ist.Even with the magnetic connection between knife carrier and strip knife the connection is very tecimic autTendig, so that here too the profitability is not given.

rsei den Scimeidemessern, die durch l}ärmebehandlung miteinander verbunden werden, ist es praktisch nicht zu vermeiden, daß Spannungen zwischen Messer und Messerträger auftreten, die dann die bekannten Risse im Messer zur Folge haben. Die Spannungen werden auch beim Nachschleifen bzw. bei der Stoßbelastung des Messers frei, so daß dann sich das Messer verzieht und der genaue Schnitt nicht mehr gegeben ist.rsei the Scimean knives, which are connected to each other by heat treatment it is practically unavoidable that tension between knife and Knife carriers occur, which then result in the known cracks in the knife. The tensions are also increased when regrinding or when the knife is subjected to impact free, so that then the knife warps and the exact cut is no longer given is.

Aufgabe der Erfindung ist es,ein Schneidemesser insbesondere für Papier- od. dergl. Maschinen zu schaffen, das an einem Messerträger einfach und sicher zu befestigen ist, wobei das Material des Messerträgers in seinen Bigenschaften unabhängig vom Material des Messers sein kann, so daß eine relativ einfache und wirtschaftliche Herstellung eines Schneidemessers gewährleistet ist.The object of the invention is to provide a cutting knife in particular for paper or the like. To create machines that are easy and safe to do on a knife carrier is to be attached, the material of the knife holder being independent in its properties from the material of the knife can be, so that a relatively simple and economical Manufacture of a cutting knife is guaranteed.

Erfindungsgemäß wird diese Aufgabe bei einem Schneidemesser für Papierschneidemaschinen, aus einem Messerträger und einem mit diesem fest verbundenen Streifenmesser dadurch gelöst, daß der Messerträger und das Streifenmesser miteinander verklebt sind.According to the invention, this object is achieved in a cutting knife for paper cutting machines, from a knife carrier and a strip knife firmly connected to this solved that the knife carrier and the strip knife together are glued.

Zweckmäßig wird als Klebemittel eine Klebefolie zwischen Messerträger und Streifenmesser eingelegt und beide bei einer Temperatur zwischen 80 bis 1200 und einer Aushärtezeit zwischen vorzugsweise 50 bis 70 min. fest unter Druck gehalten.An adhesive film between knife carriers is expediently used as the adhesive and strip knife inserted and both at a temperature between 80 and 1200 and a curing time between preferably 50 to 70 minutes, kept firmly under pressure.

Bei einem auf diese Weise hergestellten Schneidemesser hält die Verklebung bei schwerster Schnittbelastung bei maximalem Abschnitt absolut sicher.In the case of a cutting knife manufactured in this way, the bond holds Absolutely safe with the heaviest cutting load at the maximum section.

Zweckmäßig werden vor dem Einlegen der Klebefolie der Messerträger und das Streifenmesser an den Klebestellen entfettet.Before inserting the adhesive film, it is useful to use the knife holder and degrease the strip knife at the glued areas.

Die Erfindung ist nachstehend an Hand des in der Zeichnung dargestellten Ausführungsbeispieles, welches den Messerträger mit dem Streifenmesser in Seitenansicht zeigt, näher erläutert.The invention is illustrated below with reference to that shown in the drawing Embodiment, which the knife carrier with the strip knife in side view shows, explained in more detail.

Das als Streifenmesser 2 ausgebildete Schneidemesser ist mit dem Messerträger 1 durch ein Klebemittel, z.B.The cutting knife designed as a strip knife 2 is with the knife carrier 1 by an adhesive, e.g.

der Klebefolie 3 fest verbunden. Der Messerträger 1 ist in bekannter Weise an dem Messerbalken (nicht dargestellt) einer Papierschneidemaschine befestigt.the adhesive film 3 firmly connected. The knife carrier 1 is in known way on the cutter bar (not shown) of a paper cutting machine attached.

Der Messerträger 1 kann aus einem relativ billigen Stahl hergestellt werden, während das Streifenmesser aus einem hochwertigen und damit schnittfestem Stahl oder sonstigem Hartmetall besteht.The knife carrier 1 can be made of a relatively cheap steel while the strip knife is made of a high-quality and therefore cut-resistant Steel or other hard metal.

Die Verklebung kann auf kaltem Wege erfolgen, jedoch ist es zweckmäßig, die Verklebung bei einer Temperatur zwischen 80 bis 1200 und einer Aushärtezeit zwischen 50 und 70 min.Gluing can be done cold, but it is advisable to bonding at a temperature between 80 and 1200 and a curing time between 50 and 70 min.
