Abstract

Die Erfindung betrifft ein Streckwerk für eine Spinnmaschine zum Bearbeiten von Filamenten, mit wenigstens einem Eingangswalzenpaar, einem Mittelwalzenpaar sowie einem Ausgangswalzenpaar, wobei die Walzenpaare mit unterschiedlichen Umlaufgeschwindigkeiten rotieren, die Unterwalzen als teilweise geriffelte Wellen ausgebildet sind und die Oberwalzen (21o, 22o, 23o) in einem Pendelträger (12) gelagert sind.The invention relates to a drafting system for a spinning machine for processing filaments, with at least one pair of input rollers, a pair of intermediate rollers and a pair of output rollers, wherein the pairs of rollers rotate at different speeds, the lower rollers are formed as partially corrugated shafts and the top rollers (21o, 22o, 23o) are mounted in a pendulum carrier (12).

Erfindungsgemäß ist vorgesehen, dass die Oberflächen aller Walzenpaare (21, 22, 23) des Streckwerks (10) ohne Zwischenschaltung von Riemchen jeweils untereinander in Kontakt stehen, um die Filamente (27) klemmend zu führen, dabei mittels der unterschiedlichen Umlaufgeschwindigkeiten zu zerreißen und unter Ausbildung von Stapelfasern zu verziehen, dass die Belastungskraft der Ausgangsoberwalzen größer als 35 daN ist und dass in Förderrichtung der Filamente (27) hinter dem Ausgangswalzenpaar (23) eine Verdichtungseinrichtung (28) installiert ist.

Figure imgaf001
According to the invention, it is provided that the surfaces of all roller pairs (21, 22, 23) of the drafting system (10) are in contact with each other without the interposition of straps in order to clamp the filaments (27), thereby tearing and underlapping them by means of the different rotational speeds To distort formation of staple fibers that the loading force of the output top rollers is greater than 35 daN and that in the conveying direction of the filaments (27) behind the pair of output rollers (23) a compression device (28) is installed.
