Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung betrifft ' eine Schneidvorrichtung an Stoffzuschneidemaschinen, bei welcher statt der bisher üblichen rotirenden Messerscheiben " eine Anzahl nach Art einer Kette mit einander verbundener, einzelner Messer verwendet wird, die in oder an dem Führungsgriff gelagert sind und mit bezw. von demselben bewegt werden.The present invention relates to a cutting device on fabric cutting machines, in which instead of the hitherto customary rotating knife disks "a number like a Chain of interconnected, individual knives used in or on the Guide handle are stored and with BEzw. be moved by the same.

Auf der beiliegenden Zeichnung zeigt Fig. 1 eine solche Vorrichtung in der Ansicht, die Fig. 2 bis 4 zeigen verschiedene Ausführungsformen der Messerkette. In the accompanying drawing, FIG. 1 shows such a device in the view, FIGS. 2 to 4 show different embodiments of the knife chain.

Es mögen zunächst die in den Fig. 2 bis 4 gezeigten Ausführungsformen der Ketten näher besprochen werden.First of all, the embodiments of the chains shown in FIGS. 2 to 4 may be described in more detail be discussed.

Nach Fig. 2 sind die einzelnen Messer a durch je zwei Kettenglieder b verbunden, wobei der verhältnifsmäfsig breite Rücken des Messers an den Verbindungsstellen mit den Gliedern so abgesetzt ist, dafs die Glieder b nicht aus der Ebene der Messerkörper hervortreten. According to FIG. 2, the individual knives a are each connected by two chain links b , the relatively wide back of the knife being offset at the connection points with the links so that the links b do not protrude from the plane of the knife body.

'Fig. 3 zeigt eine ganz ähnliche Ausführung, nur mit dem Unterschiede, dafs die einzelnen Messer α durch je ein Glied b verbunden werden, welche in nuthenartigen Aussparungen im Messerrücken befestigt sind.'Fig. 3 shows a very similar embodiment, only with the difference that the individual knives α are each connected by a link b which is fastened in groove-like recesses in the back of the knife.

Fig. 4 endlich zeigt eine regelrechte Gall'sche Kette, bestehend aus den Gliedern b und b'. Zwischen je zwei Gliedern b ist durch einen oder mehrere Zapfen je ein Messer α befestigt. Bei allen Ausführungsformen ist vor allem darauf zu achten, dafs die Abstände zwischen den einzelnen Messern bezw. deren Schneiden nicht zu grofs werden, wie dies in den einzelnen Figuren zu erkennen ist.Finally, Fig. 4 shows a proper Gall's chain, consisting of the links b and b '. A knife α is attached between each two members b by one or more pins. In all embodiments, it is important to ensure that the distances between the individual knives and / or. the edges of which do not become too large, as can be seen in the individual figures.

Die Befestigung bezw. Führung der Kette an dem Führungsgriff ist aus Fig. 1 zu erkennen. Die Kette läuft um zwei Rollen c und d, von denen die obere c im Führungsgriff e, die andere d dagegen im Fufse f gelagert ist. Die obere Rolle wird durch einen geeigneten Mechanismus, wie er z. B. bei den bekannten, mit Messerscheiben arbeitenden Zuschneidemaschinen in Anwendung ist, angetrieben und bewegt die Messerkette in Richtung des Pfeiles.The attachment respectively. The guidance of the chain on the guide handle can be seen from FIG. 1. The chain runs around two rollers c and d, of which the upper one c is mounted in the guide handle e, while the other d is mounted in the foot f. The upper roller is driven by a suitable mechanism, e.g. B. is used in the known cutting machines working with knife disks, driven and moves the knife chain in the direction of the arrow.

Vortheilhaft erhält die Kette im vorderen schneidenden Theil noch eine Unterstützung durch eine am Führungsgriff angeordnete Leiste oder Rippe g. The chain is advantageously supported in the front cutting part by a bar or rib g arranged on the guide handle.
