Problems solved by technology

Doffing during winding interruptions can be avoided by this method, but it has been found that in the case of face yarns of this type which have run centrally onto the surface of the cross-wound bobbins, especially with relatively small In the case of yarns with a diameter of 100 mm, there is a risk of the yarn being "pressed" by the package drive rollers into the surface of the cross-wound package

Embodiment Construction

[0024] figure 1 A side view of a station 2 of a textile machine 1 (in this embodiment a so-called automatic cross-winder) for producing cross-wound bobbins is schematically shown. As is known, automatic cross-winders 1 of this type all have a large number of identically constructed stations 2 between their end frames (not shown). The worsted bobbin 3 produced on the ring spinning machine is rewound at these stations 2 to form a high-capacity cross-wound bobbin 5 which, after it has been completed, is passed through a service assembly (not shown). out), such as a cross-wound bobbin doffer, is conveyed along the length of the machine to a cross-wound bobbin transfer mechanism 7 and to a bobbin loading station arranged at the end of the machine, etc., as is known, Therefore no more detailed description will be given. Automatic cross-winders 1 of this type usually also have a logistics mechanism in the form of a bobbin and tube transport system 6 , in which the worsted bobbins 3...

Abstract

The method involves rotating a cross wound spool (5) in an unwinding direction (Z) in a frictionally engaged manner for receiving threads. A spool frame (8) is controlled by a torque sensor such that an air gap (S) is temporally provided between a surface (31) of the cross-wound spool that is held in the frame and a spool drive roller (9) that rotates the cross wound spool. A suction nozzle (35) is subjected with low pressure, before the spool, rotating in the unwinding direction, is temporally removed from the spool drive roller.

Description

technical field [0001] The invention relates to a method for operating stations of a textile machine producing cross-wound bobbins, each of said stations having a winding device having: for frictionally engaging said cross a bobbin drive roller for rotating the winding bobbins; a pivotally mounted creel for rotatably holding said cross-wound bobbins, which creel can be raised and lowered in a defined manner by a torque transmission device; and a suction nozzle, the Suction nozzles can be loaded with negative pressure and pivoted to the area of ​​the surface of the cross-wound bobbin in order to pneumatically pick up the top yarn that has run onto the surface of the cross-wind bobbin after a winding interruption. Background technique [0002] As is known, in order to produce cross-wound bobbins, it is necessary to rotate the relevant textile bobbin on the station of the textile machine about its bobbin axis and to make the yarn running on this textile bobbin also have to run ...
