Abstract

The present invention stabilizes a yarn tension in a yarn winder in which a plurality of winding units are disposed, each of the winging units being provided with a yarn slack eliminating device. A transmitted force adjusting mechanism is provided to adjust a rotative driving force transmitted by a slack eliminating roller of a yarn slack eliminating device to an unwinding tension applying member. The transmitted force adjusting mechanism can be set so that when a load acting on the unwinding tension applying member increases above a predetermined value, the unwinding tension applying member rotates or rotatively moves independently of the slack eliminating roller. When winding tension is weak, the unwinding tension applying member rotates integrally with the slack eliminating roller to tense a yarn. When the winding tension exceeds a predetermined value, the unwinding tension applying member prevents the winding tension from becoming excessive to suppress a variation in tension. When the transmitted force adjusting mechanism is configured so as to vary the force transmitted to the unwinding tension applying member, it is easy to deal with spinning conditions.

Description

technical field

[0001] The present invention relates to a yarn winding machine having a yarn slack eliminating device for eliminating yarn slack provided between a yarn supply side and a winding device; in particular, the present invention relates to such a A yarn winding machine, which employs a yarn slack eliminating device for winding up slack yarn that may occur during a yarn splicing operation, for example, to adjust when restarting the winding operation after the yarn splicing operation yarn tension, and suppresses changes in winding tension during normal winding. Background technique

[0002] In a spinning machine such as an air spinning machine, a spun yarn is produced using a sliver (fiber bundle) as a raw material, and the spun yarn is wound into a predetermined package; if a yarn defect is detected, Then the defective part of the yarn will be cut and removed by the cutter. Then, the yarn splicing device splices the front end of the yarn subsequently supplied fro...
