Problems solved by technology

The method described above is not only relatively laborious, but also requires the operator to have certain skills because three operations must be performed simultaneously.
In addition, when using such brake plates, as already explained in connection with the actuating mechanism according to DE-OS 1 560 581, there is always the fact that during the braking process the outer winding layers of the cross-wound bobbins are subjected to great stresses and thus the risk of being damaged

Embodiment Construction

[0022] figure 1 One half of a semi-automatic open-end spinning machine known per se and designated with reference number 1 is shown schematically.

[0023] This open-end spinning machine, whose workstations are manually operated by the operator to start spinning, has a large number of similar workstations 2 between the end frames (not shown) in which the individual components of the textile machine are arranged. central drive. The workstations 2 are each equipped with an open-end spinning device, a so-called spinning pot 3 and a winding mechanism 4 .

[0024] In the spinning pot 3 , the fiber strips 6 supplied in the spinning bobbins 5 are respectively spun into yarns 7 , which are then wound up on the winding mechanism 4 to form cross-wound bobbins 8 . as from figure 2 and 3 Specifically, it can be seen that the winding mechanism 4 has a creel 9 for rotatably holding the cross-winding bobbin tube 10 of the cross-winding bobbin 8, drives the winding drive roller 11 of the...

Abstract

The invention relates to a winding device for free-end spinning machine work station; the winding device comprises a pivotably movably supported spool frame for rotatably holding a cross-wound spool; a drivable spool drum provided for rotating the cross-wound spool; a device provided for lifting the cross-wound spool from the spool drum and for breaking the cross-wound spool in a standstill condition, wherein the device engages at the cross-wound spool. The invention provides a cross-wound spool brake device (13) having a brake roller (15) that is engagable at a surface (16) of the cross-wound spool (8) such that the cross-wound spool is lifted and is broken.

Description

technical field [0001] The invention relates to a winding device for a workstation of an open-end spinning machine. Background technique [0002] For textile machines producing cross-wound bobbins, such as open-end spinning machines or winders, various cross-wound bobbin braking mechanisms, as well as their winding devices, are known and described in the patent literature. If necessary, with such a braking mechanism it should be possible to decelerate the cross-wound bobbin rotatably mounted in the creel of the winding device to a standstill as quickly as possible. Such braking is necessary in the winder, for example if a yarn break occurs during the winding process, or if a controlled cleaner cut is to be triggered due to a yarn defect. [0003] As described in EP 0 846 640 B1, a workstation of such a textile machine is for example equipped with a bobbin brake which can be actuated pneumatically, is incorporated into the creel and makes it possible to be lifted from its gu...
