Embodiment Construction

[0033] The invention will be illustrated below by means of a winder 1 . However, it can also be converted analogously to a rotor spinning machine or another textile machine for producing cross-wound bobbins. The winding machine 1 has a plurality of work stations 2 . figure 1 The station 2 is shown in side view with the cross-wound converter 7 positioned previously. At station 2 yarn 12 is wound from a supply bobbin 3 , here a bobbin, onto a cross-winding bobbin 4 . figure 1 The state immediately after the exchange of the cross-wound bobbin 4 for an empty sleeve 9 is shown.

[0034] The sleeve 9 is fixed in the bobbin holder 8 and is placed rotatably. The sleeve 9 is wound onto the cross-wound bobbin 4 . The bushing 9 and the cross-wound bobbin 4 rest on a drive drum 10 and are carried by the drive drum 10 by drum friction. The station 2 also has a swivel suction nozzle 14 which catches the upper yarn connected to the cross-winding bobbin 4 and puts the cross-winding bobbi...

Abstract

The invention relates to an improved textile machine (1) for the production of cross-wound bobbins (4) when yarn (12) is wound onto cross-wound bobbins (4) located in a bobbin holder (8). A method for the problem of wire breakage at a station (2) and a winder (1). After interruption of the yarn in the normal winding process, in order to continue the winding process, the yarn connected to the cross-winding bobbins (4) is grasped and removed and replaced by the changing device (7) on the bobbin holder (8) The inner full cross-winding bobbin (4) is replaced by an empty tube (9) and the yarn supplied to the sleeve (9) is fixed at the sleeve (9) so that the winding process continues. According to the invention, when a yarn break occurs after winding an already placed sleeve (9) and a predetermined minimum yarn length has not yet been wound onto the already placed sleeve (9), the replacement device is used (7) Re-fix the yarn introduced into the supply tubes (5, 9) to the tubes (5, 9) located in the bobbin holder.

Description

technical field [0001] The invention relates to a method for solving the problem of yarn breakage when winding yarn onto cross-wound bobbins located in bobbin creels at a station of a textile machine producing cross-wound bobbins, wherein, After a yarn break during the normal winding process, in order to continue the winding process, the yarn connected to the cross-winding bobbin is grasped and removed, and wherein, by means of a changing device, the The inner full cross-winding bobbin is replaced by an empty tube and the yarn fed to the sleeve is fixed at said sleeve so that the winding process continues. The invention also relates to a textile machine with a station for winding the yarn with a processing device onto cross-wound bobbins located in the bobbin creel to continue said winding process after a yarn break. The handling device is thus designed in such a way that the yarn connected to the cross-winding bobbin is caught and removed. The changing device is thus design...
