Roller stretching arrangement of a workstation of a staple fiber processing textile machine and textile machine equipped therewith

摘要

The invention relates to a roller draw assembly (1) of a workstation of a staple fiber processing textile machine, in particular a spinning machine, a roving machine or a knitting machine, for warping at least one strand-like staple fiber band (3) entering the roller draw assembly (1) in a transport direction (T). wherein the roller draw assembly (1) has at least one draft zone delimited by an inlet side roller arrangement (6) and an outlet side (7) roller arrangement, the inlet side roller arrangement (6) comprising an inlet roller (8) and an inlet counter roller (9) cooperating therewith. and the outgoing-side roller arrangement (7) comprises an outlet roller (10) and an outlet counter-roller (11) cooperating therewith, and wherein the roller-stretching arrangement (1) comprises an endless belt (12) which separates the inlet roller (8) and one of the inlet roller (8 ) in the transport direction (T) spaced Riemchenführ (19) wraps around and thereby guided. According to the invention, the endless belt (12) is assigned at least one fixedly fixed fiber guiding element (13) which is elastic at least in sections, wherein the fiber guiding element (13) controls the staple fiber bond (3) during operation of the roller stretching device (1) against one between the Entry roller (8) and the Riemchenführung (19) extending portion of the Endlosriemchens (12) presses and this at least partially adapts to the contour of the Endlosriemchens (12).
