Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung ist eine Fadenspannvorrichtung für Spulmaschinen, die insbesondere für solche Maschinen, bei denen der Faden schnell hin- und herbewegt wird (Kreuzspulmaschinen) bestimmt ist.The present invention is a thread tensioning device for winding machines, which are particularly suitable for machines in which the thread is moved back and forth quickly (cross-winding machines) is determined.

Die bisher verwendeten Fadenspannvorrichtungen, wie Plüsch- oder Tuchleisten, Bürsten, gebremste Spannrädchen usw., müssen in einer größeren Entfernung vom Fadenführer angebracht werden, damit der Ausschlagwinkel des Fadens nicht zu groß ausfällt. Dadurch wird aber der Faden auf einer größeren freien Länge angespannt, was den Nachteil hat, daß die Fasern, besonders bei losen Garnen, auseinander gezogen werden, wodurch der Faden verschlechtert wird und öfter Fadenbrüche entstehen. The thread tensioning devices used so far, such as plush or cloth strips, brushes, braked tension wheels, etc., must be attached at a greater distance from the thread guide so that the angle of deflection of the thread is not too large. This will but the thread is tense over a greater free length, which has the disadvantage that the Fibers, especially loose yarns, can be pulled apart, causing the thread deteriorates and thread breaks occur more often.

Diesen Nachteil vermeidet die neue Erfindung. Bei derselben wird der Faden erst kurz vor dem Fadenführer bezw. der Spule angespannt.The new invention avoids this disadvantage. With the same the thread is only shortly before the thread guide respectively. the coil is tense.

Die Spannvorrichtung ist so beschaffen, daß der Faden in derselben hin- und herlaufen und daher der Bewegung des Fadenführers folgen kann.The tensioning device is designed in such a way that the thread runs back and forth in it and can therefore follow the movement of the thread guide.

In der beiliegenden Zeichnung ist die neue Fadenspannvorrichtung dargestellt, und zwar angebracht an einer Kreuzspulmaschine, die in ihren wesentlichen Teilen wiedergegeben ist.In the accompanying drawing, the new thread tensioning device is shown, namely attached to a package winder, the essential parts of which are shown.

Fig. ι ist die Seitenansicht, Fig. 2 die Vorderansicht derselben, α bedeutet die Spule, welche von der Treibwelle b durch Reibung angetrieben wird, c die schwingende Gabel, in welcher die Spule gelagert ist, d den Fadenführer, e die diesen antreibende Kurvenscheibe, f die Geradführung des Fadenführers.Fig. 1 is the side view, Fig. 2 is the front view of the same, α means the bobbin which is driven by the drive shaft b by friction, c the swinging fork in which the bobbin is mounted, d the thread guide, e the cam disk driving it , f the straight line of the thread guide.

Die Fadenspannvorrichtung besteht nun aus einer Schiene g, auf welcher Deckschienen h liegen, die durch Federn oder dergl. an erstere angepreßt werden. Die einzelnen Deckschienen stoßen vor den Mitten der Spulen zusammen. Damit nun der Faden trotz der Unterbrechung der Deckschiene stets unter Spannung bleibt, sind die Enden der Deckschienen schräg abgeschnitten, so daß die eine Schiene den Faden nicht eher freigibt, bevor die andere denselben erfaßt hat. Ferner sind die Spitzen der schrägen Enden der Deckschienen aufgebogen, womit erreicht wird, daß bei Inbetriebsetzung der Spule (nach erfolgtem Anknüpfen eines abgerissenen Fadens oder bei Beginn einer Spule) der Fadenführer den Faden selbsttätig in die Spannvorrichtung einzieht.The thread tensioning device now consists of a rail g on which cover rails h lie, which are pressed against the former by springs or the like. The individual cover rails collide in front of the centers of the coils. So that the thread always remains under tension despite the interruption of the cover rail, the ends of the cover rails are cut off at an angle so that one rail does not release the thread before the other has gripped it. Furthermore, the tips of the inclined ends of the cover rails are bent up, so that when the bobbin is put into operation (after a broken thread has been tied or at the beginning of a bobbin) the thread guide automatically pulls the thread into the tensioning device.

Claims (2)

Patent-Ansprüche:Patent Claims: i. Fadenspannvorrichtung für Spulmaschinen, dadurch gekennzeichnet, daß der Faden zwischen einer Unterschiene und einer durch Federn oder dergl. an diese angepreßte Deckschiene hindurchgeführt wird, zum Zweck, dem Faden freie Beweglichkeit in Richtung des Fadenführerweges zu ermöglichen und die Spannvorrichtung dicht vor der Spule anbringen zu können.i. Thread tensioning device for winding machines, characterized in that the Thread between a lower rail and one by springs or the like. To this pressed cover rail is passed through, for the purpose of free movement of the thread in the direction of the thread guide path and to attach the tensioning device close to the bobbin can. 2. Fadenspannvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Deckschienen auf der Mitte der Spule mit schrägen, aufgebogenen Enden zusammengestoßen sind, zum Zweck, den Faden an jeder Stelle unter Spannung zu halten und das selbsttätige Einlegen des Fadens in die Spannvorrichtung durch den Fadenführer zu ermöglichen.2. Thread tensioning device according to claim 1, characterized in that the cover rails in the middle of the bobbin with sloping, bent-up ends butted together for the purpose of attaching the thread every point under tension and the automatic insertion of the thread into the Allow tensioning device through the thread guide.
