Method for threading in a thread

Abstract

The present invention relates to a method for threading a thread (16) into a guide slot (21) of an individually driven, finger-shaped thread guide (13) of a textile machine, which thread guide (13) guides the thread (16) parallel to the spool axis via an oscillating stroke width in order to transfer a thread (16) on a rotating spool (5), wherein the thread guide (13) is transferred into an initial position (A) before the beginning of the threading operation; the thread guide (13) is then transferred into a threading position (E) and drives the thread (16) which is to be threaded in; a relative movement is generated here between the thread guide (13) and the thread (16), in order to thread the thread (16) into the thread guide (16); and the thread (16) is held with tension for the threading operation.

Description

technical field [0001] The invention relates to a method of operating a textile machine as stated in the preamble of claim 1 . Background technique [0002] In textile machines producing bobbins (e.g. winding machines or open-end textile machines), it is arranged to activate the yarn connection in the event of interruptions in the yarn supply due to yarn breakage or replacement of bobbins or bobbins and similar causes operation to resume normal operation. In this case, after the yarn breaks, the yarn is usually located outside the yarn guide (which traverses the yarn during winding), so when the yarn connection is completed, the yarn must return to the guide. in the yarn container. [0003] DE 39 30 136 A1 discloses a method for passing a yarn through a yarn guide at the winder of a textile machine, the yarn being transferred by means of a yarn transfer device to a separately driven back and forth yarn guide. For this purpose, the movement of the yarn transfer device and ...

AI Technical Summary

Problems solved by technology

[0004] The complexity of the device to monitor the yarn transfer device and the yarn guides to determine the exact moment and transfer position proved to be a disadvantage

In addition, in the method disclosed in DE 39 30 136 A1, since the transfer of the yarn takes place at the beginning of the package run, there may be entrained or disordered layers on the package, which are detrimental to the subsequent unwinding behavior Impact
