Method for restarting twisting device after end breaking of yarn

Abstract

A method for restarting a twisting device comprising a twisting spindle (A) and a winding device (B) after a yarn breakage, in which method the twisted yarn is fed from a drum downstream of the twisting spindle ( S) under unwinding, fix it on a fixed point after twisting the yarn to obtain a yarn section with a complete number of twists, and fix it at a position behind the fixed point, that is, in the fixed position viewed from the groove drum It is cut at such a position after the fixed point, and then the single yarn located behind the fixed point is mechanically or manually knotted or spliced ​​with the spinning end from the twisting spindle, and before that, the winding process It is necessary to delay the start after the re-running of the twisting spindle until the predetermined number of twists for the twisted yarn returns to the fixed point through the knotting position or the splicing position.

Description

technical field

[0001] The invention relates to a method for restarting a twisting device comprising a twisting spindle and a winding device after a yarn break, after which the twisted yarn is unwound from a drum downstream of the twisting spindle , before the twisting spindle and the groove drum restart, that is, before the rotation, the single yarn end is mechanically or manually knotted or spliced ​​with the spinning end from the twisting spindle.

[0002] This method requires, after knotting or splicing, to have as much as possible the same number of twists on the twisted length defined by the knotting position or the splicing position as the entire twisted length wound on the drum, thus ensuring The evenly twisted yarn required by the subsequent processing industry can be obtained by full winding in the groove drum. technical background

[0003] In the event of a yarn break, it is simpler to unwind or extract the twisted end from the drum and prepare a yarn end with a ...
