Winding cross wound bobbins, at a bobbin winder, starts the yarn at a given crossing angle at the start of the winding cycle, with an increased angle during winding for consistent bobbins

摘要

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.
