Method for correcting yarn movement at a textile machine station for the manufacture of cross-wound bobbins

Abstract

The invention relates to a method (100) of correcting yarn movement at a station (2) of a textile machine (1) for manufacturing cross-wound bobbins. The station (2) comprises a device for withdrawing the yarn (19), a device (50) for winding the withdrawn yarn (19) into a cross-wound bobbin (16) and a device arranged between the withdrawal device and the winding device (50) and can swing to different positions of the yarn catcher (12), the yarn catcher is at least used to receive and transfer the received yarn end, here, the yarn catcher (12) has a function for entraining the yarn segment the entrainment mechanism. The method (100) comprises a first step (110) of oscillating the yarn catcher (12) to an initial position (I) in which the entraining mechanism is in contact with the yarn moving between the withdrawal device and the winding device opposite. The method (100) is characterized in that the method (100) comprises the second step of swinging the yarn catcher (12) entraining the yarn (19) from the initial position (I) to a withdrawal position (III) spaced apart from the initial position. Step (120) and a third step (130) of releasing the yarn (19) under tension in the release position (IV).

Description

technical field [0001] The invention relates to a method according to the invention for correcting the yarn movement at a station of a textile machine for manufacturing cross-wound bobbins. Background technique [0002] Such textile machines, such as cross-winding winders and open-end rotor spinning machines, have long been known and are described in detail in numerous patent documents (eg documents DE10224080A1 and DE102009030802A1). [0003] What these textile machine types have in common is that the supplied yarn is wound into bobbins in the area of ​​the winding device, where, for example, in the event of a yarn break, the broken yarn end is caught by a yarn catcher and passed on In order to subsequently manufacture the yarn that moves from the yarn withdrawal device to the yarn winding device. For connecting disconnected yarns, cross-winding winders are usually equipped with yarn splicers, while open-end rotor spinning machines are equipped with piecing devices, which ...

Problems solved by technology

When continuing to run automatically, the yarn may not be able to autonomously return to the yarn travel path, whereby a yarn traveling in a section outside the yarn travel path may cause friction-dependent malfunctions, possibly accompanied by damage to textile machine components
