Embodiment Construction

[0028] In essence obtained from EP0399243B1 and there as figure 2 and shown in Figure 5 figure 1 and figure 2 In , the winding position 1 of the winding machine set up according to the invention is shown simplified in a schematic front view and a side view.

[0029] In the winding position 1 , the cross-wound bobbin 8 mounted in the bobbin holder 9 is driven by means of friction by the drive drum 2 . At this time, the yarn 7 drawn out from the bobbin 28 is wound onto the cross winding bobbin 8 . The yarn 7 is laid parallel to the axis of the cross-winding bobbin 8 by means of the reverse thread groove 2" of the drive drum 2. The desired cross-winding then takes place.

[0030] The drive drum 2 is mounted in the frame 3 of the winder via a drum shaft 2'. The drive of the drum shaft 2' is achieved by means of pulleys 4 and 4' connected with a V-belt 4", wherein the pulley 4' is driven by an electric motor 6'. However, instead of using the belt drive mechanism 4, 4', 4", it...

Abstract

The present invention relates to a method and an apparatus to avoid ribbon winding when winding a cross-wound bobbin, the driving drum provided with one having spiraled grooves for the thread guide is driven, wherein the drive drum comprises acceleration phase, each by a deceleration phase be immediately followed, characterized in - that the drive roller during the acceleration (BP) and deceleration phases a higher peripheral speed than the cheese, - that the deceleration phases be completed in the time in which the peripheral speed of the drive pulley to the cheese has fallen, - and that the deceleration phases are each followed by a synchronous phase, in which the peripheral speeds drive of the drum and cross-wound bobbin are equal.

Description

technical field [0001] The present invention relates to a method of avoiding pattern winding when winding cross-wound bobbins and a device for carrying out such a method. [0002] The cross-wound bobbins are produced by a corresponding textile machine, which generally consists of a number of identical stations, each of which produces the cross-wound bobbins, which are powered by a central device of the textile machine, for example a power supply. Such a textile machine may especially be an automatic winder, which rewinds a plurality of relatively small packages into cross-wound bobbins with much more yarn material, or it may also be a spinning machine . Background technique [0003] In cross-wound bobbins, the yarn is wound obliquely with respect to the longitudinal axis of the cross-wound bobbin. At this point, the yarn first moves from the left end side of the cross-wound bobbin to its right end side, for example with an inclination to the right, so that it then changes ...
