Method for manufacturing cross winding bobbin

Abstract

To produce a cross wound bobbin (11), at the workstation (2) of a bobbin winder (1), the yarn (30) is wound at the start of a winding cycle at a crossing angle to increase the density of the bobbin core. The crossing angle is increased significantly during the winding cycle, so that the density of the wound bobbin is reduced progressively outwards. The increased crossing angle acts against the yarn laying width, and the stroke movement of the reciprocating yarn guide (29) has a defined increase.

Description

Technical field [0001] The invention relates to a method of manufacturing a cross-wound bobbin as described in the preamble of claim 1. Background technique [0002] Such a cross-wound bobbin is formed on a cross-wound automatic device, for example. That is, in the station of the spinning machine, a relatively small small bobbin is wound into a large cross-wound bobbin, and the small bobbin is preferably spun on a ring spinning machine. In addition, the unevenness of the yarn is also detected during the winding process, so as to remove the bad yarn. [0003] In order to enable this kind of cross-wound bobbin to be processed in an orderly manner in the subsequent process, the cross-wound bobbin should have good unwinding properties. The unwinding properties of cross-wound bobbins may be affected by, for example, the way in which the yarn layers shift during manufacturing. There are two types of yarn displacement modes, the so-called "rough winding" and "fine winding". [0004] The...
