Description

Messerband für Stoffzuschneidemaschinen. Während bei den bisher verwendeten Stoffzuschneidemaschinen entweder kreisende Messerscheiben oder aber eine Anzahl nach Art einer Kette (Messerkette) miteinander verbundener Messer, welche über Kettenräder geführt sind, verwendet werden, zeigt vorliegende Erfindung ein Messerband, bei welchem die Messer mittels Blattfedern an einem endlosen Metallband angelenkt sind und an ihrer hinteren Ecke durch eine Feder nachgiebig gegen das Metallband abgestützt sind.Knife tape for fabric cutting machines. While with the ones used so far Fabric cutting machines either rotating knife disks or a number knives connected to one another in the manner of a chain (knife chain), which have sprockets are used, the present invention shows a knife tape which the knives are hinged to an endless metal band by means of leaf springs and at its rear corner supported resiliently against the metal band by a spring are.

Durch diese Anordnung wird bei ruhigem Gang eine große Schnittgeschwindigkeit und eine gerade Schnittfläche zum Schneiden von kleinen Kurven erzielt.This arrangement results in a high cutting speed when the gear is smooth and achieves a straight cutting surface for cutting small curves.

Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt Abb. i eine Seitenansicht nach Abnahme des Gehäusedeckels, Abb. a die Stirnansicht, teilweise im Schnitt, Abb. 3 einen Querschnitt nach derLinie A-B in Abb. i, während in Abb. q. und 5 ein :Messer mit seiner Befestigung in größerem Maßstab als Ansicht bzw. Schnitt. gezeichnet ist.The subject of the invention is shown in the drawing, namely Fig. i shows a side view after removing the housing cover, Fig. a shows the front view, partially in section, Fig. 3 shows a cross section along the line A-B in Fig. i, while in fig.q. and 5 a: knife with its attachment on a larger scale as a view or cut. is drawn.

Wie aus Abb. i ersichtlich ist, besteht das Messerband aus einer beliebigen Anzahl Messer a, welche durch die Blattfedern b mittels der Niete d an dem endlosen Band c aus Stahl o. dgl. befestigt sind. Das Band c mit den daran befestigten Messern a wird durch zwei Rollen h und i bewegt, wobei die Rolle h die getriebene und die Rolle i die treibende ist; letztere wird durch eine biegsame Welle oder mittels Winkelräder durch einen aufgebauten Elektromotor angetrieben. Die Rollen sind in bekannter Weise an der Lauffläche mit Leder oder Gummi überzogen.As can be seen from Fig. I, the knife band consists of any number of knives a, which are attached to the endless band c made of steel or the like by the leaf springs b by means of the rivets d. The belt c with the knives a attached is moved by two rollers h and i , the roller h being the driven and the roller i the driving; the latter is driven by a flexible shaft or by means of angular gears by a built-on electric motor. The rollers are covered in a known manner on the tread with leather or rubber.

Die Befestigung der Messer d (Abb. q. und 5) an dem Bande c geschieht in der Weise, daß die Blattfeder b durch den mit rechteckigem Schaft versehenen Niet d an das Band angenietet wird, während die aufgebogenen Lappen der Blattfeder b in den in das Messer eingenieteten Bolzen x eingreifen und auf dem Bolzen x gleichzeitig die Führungsrolle e sitzt. An der hinteren Ecke des Messers ist ein zweiter Bolzen x eingenietet, welcher die kleine Feder f mit der zweiten Führungsrolle e trägt. Die Feder f dient zur Abstützung gegen das Band c und zum Anpressen der Rolle e gegen die dem Band gegenüberliegende Lauffläche des Gehäuses h. Dadurch wird einer Schleuderbewegung des schnellaufenden Bandes vorgebeugt und ein ruhiger Gang der Maschine erzielt. An der unteren Rollenlagerung ist eine Pflugschar mit schraubenartiger Fortsetzung y angebracht, welche dazu dient, den Stoff kurz hinter der Schnittfläche seitwärts zu drehen, um die Vorwärtsbewegung des Bandes zu erleichtern.The attachment of the knives d (Fig. Q. And 5) to the band c is done in such a way that the leaf spring b through the provided with a rectangular shaft Rivet d is riveted to the band, while the upturned tabs of the leaf spring b Engage in the bolt x riveted into the knife and on the bolt x at the same time the guide roller e is seated. There is a second bolt on the back corner of the knife x riveted, which carries the small spring f with the second guide roller e. The spring f is used to support against the band c and to press the roller e against the running surface of the housing opposite the belt h. This becomes one The spinning movement of the fast-moving belt is prevented and the Machine achieved. On the lower roller bearing is a ploughshare with a screw-type Continuation y attached, which serves to put the fabric just behind the cut surface rotate sideways to ease the belt forward movement.
