Abstract
Thread twist system for twisting and spinning machines which comprises means (12) for measuring and/or calculating directly or indirectly the rotation speed (11) of the runner (5), in such a way that the working movements and parameters of the machine keep real twisting constant throughout the process of filling the reel (2) in a dynamic and instantaneous way, by acting on the angular speed (10) of the spindles (1) and/or the feeding (9) speed of the thread (6), with the objective of correcting the theoretical twisting on the thread itself (6) and converting it into real twisting.
Claims4
Thread twist system for twisting and spinning machines including a rotatable spindle, a reel attached to the spindle and disposed to rotate therewith, a ring disposed to extend around the reel, a rotatable runner carried on the ring and being rotatable at a variable rotational speed, and a thread feed pulley disposed to feed thread to the runner at a variable thread feed speed to fill the reel with thread, wherein the thread twist system comprises:
- means for determining the rotational speed of the runner;
- and
- means for maintaining the ratio of the runner rotational speed and the thread feed speed at a constant value, whereby torsion variation of the twisted thread is minimized.
