APPARATUS FOR TWISTING OR FALSE-TWISTING A MULTIFILAMENT YARN

摘要

1. Apparatus for twisting a false-twisting a multifilament yarn (14), in which the yarn (14) is clamped between a driven, endless, flexible belt (11, 12...) ther rear face of which, which is opposite to the yarn (14), is contacted by a pressure applying stamp (18, 23, 49, 129, 211, 222), and between a second moving friction surface, characterized by the fact that there is provided a pressure stamps for each yarn which is designed such that the belt (11, 12) is buckled out towards the yarn (14) within a yarn engaging zone (3, 4, 210, 237) which is defined by the pressure applying surface (24, 53, 126) of the pressure stamp (18, 23, 49, 129, 211, 222), by a resilient pressure force extented by the stamp (18, 23, 49, 129, 211, 222).
