Embodiment Construction

[0016] figure 1 Shows a perspective view of a workstation 1 of an open-end rotor textile machine, which is only shown schematically because it is known, with an open-end spinning mechanism 2 and a winding mechanism 3 for producing a yarn 9 , the winding mechanism is connected downstream in the yarn running direction F. Yarn 9 is wound onto said winding mechanism 3 to form a cross-wound bobbin 8 .

[0017] As shown, the yarn 9 produced in the open-end spinning mechanism 2 is drawn out from the open-end spinning mechanism 2 by means of a yarn drafting device 27 which has a yarn draft driven by a single motor. A pulling roll 10, and a pressure roll 14, which may be positioned on the yarn pulling roll 10 and driven by frictional engagement.

[0018] In addition if figure 1 As shown, the yarn 9 leaves the free-end spinning mechanism 2 through a so-called yarn drafting tube 21, in the region of which a pivotally mounted auxiliary joint member 16 is also provided, after the yarn h...

Abstract

Method for spooling a thread (9) on a textile machine which produces crosswound bobbins (8) and has a multiplicity of work stations (1) of the same kind, wherein each work station (1) comprises a thread traversing device (24) for laying the thread (9) during the normal operation of the textile machine with a nominal stroke on a crosswound bobbin (8) which is driven by a winding shaft (23), and anapparatus (2) for eliminating the interruption of the thread (9), wherein, after the thread interruption has been eliminated, first of all a defined thread length is stored in a thread storage device(12), wherein the nominal stroke of the thread traversing device (24) of the work station (1) is shortened after the elimination of the thread interruption for the duration of spooling of a defined thread length onto the crosswound bobbin (8).

Description

technical field [0001] The invention relates to a method for winding yarn on a textile machine for producing cross-wound bobbins, and a textile machine for producing cross-wound bobbins. Background technique [0002] A textile machine for producing cross-wound bobbins is known from DE 10352819 A1, which has several workstations. Yarn is produced at the workstation with an open-end spinning unit, which is moved on cross-wound bobbins by a yarn traverse device driven by a single motor. When a yarn break occurs, a spinning process is started to eliminate it. While the movement of the yarn on the cross-wound bobbin continues, a temporary overlength of the yarn occurs. This is due to the different actuation speeds of the workstation's individual motor-driven components. Therefore, the lag of the winding shaft for driving the cross-winding bobbins relative to the yarn take-off rollers for drawing the yarn from the spinning mechanism leads to overlong yarns, which are temporaril...
