Abstract

Yarn package carrier is rotatable on a spindle on which a pulley is freely rotatable, the pulley being wrapped by a belt to which a load is attached to brake the pulley by friction. The pulley is connected to the package by a resilient member. Specif. the load is a weight or a tension spring, and a mandrel which carries the package is connected to the pulley by a coil spring.

Description

F adenspannvorrichtung Die Erfindung betrifft eine Fadenspannvorrichtung zum Einstellen der Spannung eines von einem Paket abgezogenen Fadens oder Garns. Im vorliegenden Fall umfaßt der Ausdruck "Garn" oder "Faden" jede Art eines draht- oder fadenförmigen Materials, worunter auch Bänder und irgendwelche Gewebe oder Filme in Bandform zu verstehen sind. Thread tensioning device The invention relates to a thread tensioning device for adjusting the tension of a thread or yarn withdrawn from a package. In the present case, the term "yarn" or "thread" includes any type of wire or thread-like material, including ribbons and any fabric or Films are to be understood in tape form.

Gemäß der erfindung wird eine Fadenspannvorric.htung vorgesctllagen, bei weicher eine Seil- oder Riemenscheibe frei drehbar- auf einer Welle angeordnet ist, wobei diese Welle zum Aufstecken eines Faden- oder Garnpakets dient, die Riemenscheibe umschlungen wird von einem Riemen, der mit einer Kraft belastbar ist und zwischen der Riemenscheibe und dem Faden- bzw. According to the invention, a thread tensioning device is provided, with softer a rope or belt pulley freely rotatable - arranged on a shaft is, this shaft is used to attach a thread or thread package, the pulley is wrapped around by a belt that can be loaded with a force and between the pulley and the thread resp.

Garnpaket elastische Verbindungsmittel vorgeschen sind.Yarn package elastic lanyards are provided.

Ein Ausführungsbeispiel wird nachfolgend anhand der Zeichnung näher erläutert. An exemplary embodiment is described in greater detail below with reference to the drawing explained.

Eine Welle 10 ist starr mit dem Peil 11 verbunden, bei welchem es sich beispielsweise un einen Teil eines Maschinenrahmens handeln kann. Auf diesem Welle oder Achse 10 ist frei drehbar eine Seil- oder Riemenscheibe 12 angeordnet, welche mindestens teilweise von einem Riemen 13 umschlungen wird, an welchem ein Gewicht 14 hängt. A shaft 10 is rigidly connected to the bearing 11, in which it For example, it can be a part of a machine frame. On this one Shaft or axis 10 is freely rotatable a rope or belt pulley 12 is arranged, which is at least partially wrapped by a belt 13 on which a Weight 14 depends.

Eine Ende einer Wendelfeder 15 ist an der Riemenscheibe 12 und das andere Ende an einem Dern 16 befestigt, wol>ei dieser l)orn 16 drehbar auf der Welle 10 angeordnet i.st und ein Faden- oder Garnpaket 17 trägt, welches abzuwickeln ist. One end of a helical spring 15 is on the pulley 12 and the the other end is attached to a core 16, so this l) orn 16 can be rotated on the Shaft 10 arranged i.st and a thread or yarn package 17 carries, which unwind is.

Wird ein Fadenende vom Paket 17 abgezogen, wird die Feder 15 so weit aufgewickelt, bis die Federspannung die Reibung zwischen dem Riemen 13 und dem Riemenscheibenrand 12 überwindet, so daß die Riemenscheibe zusammen mit dem Dorn 16 sich zu drehen beginnt, wodurch die Reibung zwischen er itiemenscheihe 12 und dem Riemen 13 eine vorbestimmte Spannung im abzuziehenden Faden bewirkt. If a thread end is pulled from the package 17, the spring 15 becomes so wide wound until the spring tension eliminates the friction between the belt 13 and the pulley rim 12 overcomes, so that the pulley together with the mandrel 16 to rotate begins, whereby the friction between he itiemenscheihe 12 and the belt 13 a causes predetermined tension in the thread to be withdrawn.

Es ist klar, dan die Fadenspannung abhängig ist von der vorgenannten Reibung, die wiederum abhängig ist von der durch das Gewicht 14 erzeugten Kraft. It is clear that the thread tension depends on the above Friction, which in turn depends is different from that by weight 14 generated force.

Beim Abwickeln des Faden- oder Garnpakets kann das Garn bzw. der Faden zeitweilig seine Spannung verlieren, was jedoch dazu führt, daß die Wendelfeder sich um einen Betrag entspannt, der ausreichend ist, daß der Faden wiederum gesl)annt wird und <lie richtige Fadenspannung sich wieder einstellt. When unwinding the thread or thread package, the thread or the Thread temporarily lose its tension, but this leads to the spiral spring relaxes by an amount sufficient for the thread to weave again and the correct thread tension is restored.

Da die Fadenspannung proportional der durch das Gewicht 14 erzeugten Kraft ist können verschiedene Gewichte dafür vorgeschen sein, eine bestimmte Faden-oder Garnspannung zu erzeugeh. Selbstverständlich kann das Gewicht 14 ersetzt sein durch irgendwelche eine Kraft erzeugenden Mittel, wie beispielsweise ene Spannfeder. Since the thread tension is proportional to that generated by the weight 14 Kraft is can be given a certain thread or different weights To generate yarn tension. Of course, the weight 14 can be replaced by any force generating means such as a tension spring.
