Embodiment Construction

[0030] figure 1 A winding device 1 for carrying out the method according to the invention is shown. The winding device 1 comprises a creel 2 for rotatably supporting cross-wound bobbins 3 . This means that between the creel arms of the creel 2 there is rotatably mounted a cross-wound bobbin 3 , the surface of which bears on a drive roller 5 and is driven by it by frictional contact.

[0031] To this end, said drive roller 5 is connected to a motor-only drive 6 , which in turn is connected via a control line 21 to the control device 10 .

[0032] Of course, different types of drive means for rotating the cross-wound bobbin 3 are also possible, in addition to frictionally driving the shown drive roller 5 of the cross-wound bobbin 3 . The cross-wound bobbin 3 can likewise be directly driven, for example by means of a spindle drive (not shown), ie a drive acting on one of the sleeves 21 supporting said cross-wound bobbin. Such a spindle drive is therefore preferably arranged on...

Abstract

The invention relates to a method of manufacturing cross-wound bobbins. In the method, the wiring device (12) performs a first wiring run (41, 51) with a first run length (h1) and a second wiring run (44, 54) with a different second run length (h2) . According to the invention, the length (h1, h2) of the inversion region (41.1, 44.1, 51.1, 54.1, 41.2, 44.2, 51.2, 54.2) of said first and second wiring runs (41, 51, 44, 54) Can be adjusted relative to each other so that in an intermediate region (45, 55) between inversion regions (41.1, 44.1, 51.1, 54.1, 41.2, 44.2, 51.2, 54.2) said first and second wiring runs (41 , 51, 44, 54) have the same wiring speed, and the wiring frequencies of the first and second wiring runs (41, 51, 44, 54) are consistent.

Description

technical field [0001] The invention relates to a method of manufacturing a cross-wound bobbin, wherein a thread is wound on a rotating cross-wound bobbin, wherein the thread is wound on the cross-wound bobbin by means of a routing device located on the cross-wound bobbin, wherein The routing device performs a routing run in which the routing device is accelerated to routing speed in an inversion region starting from a reversal point at one end of the routing run and to another reversal in the other reversal region at the opposite end of the routing run The point decelerates again, and wherein the wiring device performs a first wiring stroke of a first stroke length and a second wiring stroke of a different second stroke length. Background technique [0002] Cross wound bobbins can be manufactured by random winding, precision winding or step precision winding. The term "cross-wound bobbin" as used herein also includes bobbins accumulated during winding of cross-wound bobbin...
