Problems solved by technology

[0012] However, the above-mentioned lap prevention method or lap prevention mechanism has the disadvantage of being relatively complicated or expensive.
[0013] In other words, either high mechanical and control expenditures are required to implement these known methods, or these lap prevention methods give unsatisfactory results during the winding of cross-wound bobbins

Embodiment Construction

[0028] figure 1 A side view of one half of a textile machine 1 producing cross-wound bobbins is schematically shown in an embodiment of an open-end rotor spinning machine. As is known, a textile machine of this type has between its end frames (not shown) a large number of similar workstations 2 which, among other things, each have a spinning unit 3 and a winding device 4 . The fiber strip 6 stored in the spinning container 5 is processed in the spinning unit 3 into yarns 7, which are then wound on the winding device 4 to form cross-wound bobbins. The completed cross-wound bobbin 8 is conveyed, for example, by means of a cross-wound bobbin transport mechanism 12 to a loading station (not shown) arranged at the end of the machine.

[0029] as in figure 1 As shown in , each workstation 2 has other processing mechanisms besides the spinning unit 3 and the winding device 4 , such as a thread take-off mechanism 10 , a suction nozzle 17 or a waxing device 14 . The function of the...

Abstract

The invention relates to a method for avoiding ribbon windings in the production of winding-on bobbins which are wound as a 'randomly wound package' type on the workstations of textile machines which manufacture crosswound bobbins, by changing the crosswinding, with which the thread is wound onto the winding-on bobbin, wherein the workstations have in each case a single-motor drive which can be actuated in a defined manner for rotating the crosswound bobbin and a single-motor drive which can be actuated in a defined manner for an oscillating thread guide. According to the invention, there is provision for the diameters (DSP

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for avoiding lap windings during the manufacture of winding bobbins. Background technique [0002] During the manufacture of wound bobbins at a workstation of a textile machine for the manufacture of cross-wound bobbins, the yarn produced, for example in an open-end spinning device and supplied to the winding device at a substantially constant speed while running onto the bobbin is in the yarn The displacement under the action of the traversing guide so that it runs onto the bobbin in cross-layers to form a so-called cross-wound bobbin. However, during the manufacture of cross-wound bobbins in this "random winding" type of winding, there is the problem that, if no special measures are taken, the so-called double-coil winding occurs repeatedly during the bobbin travel. . Such lap winding tends to occur if there is an integer number of winding ratios, in other words if the cross-win...
