AI Technical Summary

Problems solved by technology

The dragged yarn can run through several adjacent working positions and can be wound onto adjacent bobbins, which can cause problems when continuing processing later, since the unwinding of the bobbins is hindered

Embodiment Construction

[0032] The invention can be used on different textile machines for winding a running yarn F onto an empty bobbin H ( FIG. 1 ) of eg a winding machine or an open-end spinning machine.

[0033] The following description relates to an air spinning machine comprising a plurality of similarly constructed air spinning devices 1 arranged side by side, each air spinning device 1 having a drawing tube 10 through which the yarn F can be passed Pulling rolls 11 , 12 are drawn out of the air spinning device 1 to be fed to the winding device 4 . The winding device 4 has two bobbin arms 40 and 41 which are pivotally supported on a shaft 42. An empty bobbin H for winding a yarn F is rotatably supported on the bobbin arms 40 and 41 by means of two bobbin discs (Hülsenteller ) 400 and 410 can be mounted between the bobbin arms 40 and 41. One of the bobbin reels is in this exemplary embodiment a bobbin reel 400 designed as a winding device 47 and thus has a plurality of stops 470 .

Abstract

A retaining force on a sewing thread (F) stretching into a suction tube (20) is increased for the duration of a cutting process being undertaken by gripping the thread in the suction tube. Pressure applied to the thread held back by gripping can be increased against a thread cutter (6) through additional movement of the suction tube. An independent claim is also included for a device for servicing an operating point on a textile machine.

Description

technical field [0001] The invention relates to a method and a device for maintaining the working position of a loom, in particular a method for maintaining the working position on a loom and a device for implementing the method. Background technique [0002] It is known to feed the yarn by means of a suction nozzle to a winding device which rotates around the empty bobbin after the empty bobbin has been inserted and further driven when the bobbin is changed by means of a running maintenance device. After the winding-up device accepts the yarn, the yarn is input into the yarn cutting device along with the rotation of the winding-up device, so that the yarn end is a certain length. Failure of the cutting operation can occur due to contamination or wear of the cutting member of the yarn cutting device. If the maintenance device is far away from the maintained working position after the maintenance work is finished, the length of yarn to be drawn from the suction nozzle will a...
