Problems solved by technology

However, this patent is not suitable for such a situation, as, in the case of restarting a twisting device after a yarn breakage, the yarn ends from the twisting spindles are not mutually twisted, i.e. do not have a twist number, therefore For the knotting or splicing process, only two separate, untwisted spinning ends

Embodiment Construction

[0019] In particular, each two-for-one twisting spindle and winding device can be run and stopped independently of the remaining two-for-one twisting spindles or the remaining winding devices of the entire machine.

[0020] During the operation of the machine, the twisted yarn 2 produced by the operation of the two-for-one twisting spindle A passes through the pigtail-shaped yarn guide 1 located on the extension of the hollow shaft of the spindle, and then passes through a traditional yarn feeding device 2, and passes through The overfeed yarn mechanism 3 is then wound onto a drum S driven, for example, by a friction drive roller 5 .

[0021] When the twisting device is restarted after a yarn break, the end of the twisted thread unwound from the grooved drum S is inserted into a splicer or knotter 6 and fixed on a fixed point therein, Make the end of the twisted thread between the fixed point and the drum S have a complete number of twists, and after the fixed point, that is, ...

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 ...
