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 transported along the length of the machine to the 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 bobb...

Abstract

The present invention relates to a method for operating workplaces on a textile machine for creating cross-wound spools, wherein each workplace is provided with a coiling device which comprises the following components: a spool driving roller which is used for rotating the cross wound spool through friction joint; a spool frame which is used for rotatably keeping pivotable mounting of cross wound spool and can be lifted by a torque transfer device with a limited mode; and a suction nozzle which is loaded with negative pressure and can pivot to the surface area of the cross wound spool for pneumatically picking the surface yarn which operates to the surface after coiling interruption. For picking the yarn, the cross wound spool (5) firstly rotates along a uncoiling direction (Z) through friction joint. Then a spool frame (8) is activated by a torque transfer device (60) so an air gap (S) is temporarily formed between a surface (1) of the cross wound spool (5) kept on the spool frame (8) and the spool driving roller (9) for rotating the cross wound spool (5).

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 ...
