Abstract

Die Erfindung betrifft bezieht sich auf ein Streckwerk bei einer Textilmaschine, insbesondere Ringspinnmaschine, mit einem Eingangswalzenpaar (2), einem Ausgangswalzenpaar (4) sowie einem zwischen dem Eingangs- und Ausgangswalzenpaar angeordneten Mittelwalzenpaar (3), deren Walzen jeweils von Riemchen (8,9) umschlungen sind, die über Umlenkelemente laufen. Erfindungsgemäß ist zwischen der Unterwalze (3.2) des Mittelwalzenpaares und der Unterwalze (4.2) des Ausgangswalzenpaares ein Freilauf (20) angeordnet, durch dessen Sperrwirkung ein Vorlauf der Unterwalze (3.2) des Mittelwalzenpaares gegenüber der Unterwalze (4.2) des Ausgangswalzenpaares verhinderbar ist.

Figure 00000001
The invention relates to a drafting system in a textile machine, in particular a ring spinning machine, with an input roller pair (2), an output roller pair (4) and a central roller pair (3) arranged between the input and output roller pair, the rollers of which are each provided by aprons (8,9 ) are wrapped, which run over deflection elements. According to the invention, a freewheel (20) is arranged between the lower roller (3.2) of the middle roller pair and the lower roller (4.2) of the output roller pair, by means of its locking action preventing the lower roller (3.2) of the intermediate roller pair from advancing towards the lower roller (4.2) of the output roller pair.
