Problems solved by technology

[0006] Since the dyed bobbin is first partially rewound into an A-quality bobbin at the first winder and then transferred to the second winder, the yarn layer remaining on the dyed bobbin is wound at the second winder. Rewinding into a B-quality bobbin, so the disadvanta

Embodiment Construction

[0022] Fig. 1 schematically shows a front view of a textile machine that produces cross-wound bobbins, that is, an automatic cross-wound machine in this embodiment, which is denoted by reference numeral 1 as a whole. The automatic cross-winding machine 1 has a large number of workstations between its end frames 35, 36, so-called winding heads 2.

[0023] As can be specifically seen from FIG. 2, the dyeing bobbin 4 is rewinded on the winding head 2 to form a cross-winding bobbin 11. The completed dyeing bobbin 4 newly rewinded to form the cross-wound bobbin 11 is transported to the conveying device 21 by the automatic operation service unit, for example, by the cross-wound bobbin changer 23, which transfers the cross-wound bobbin 11 Transport to a bobbin loading station (not shown) etc. arranged at the end of the machine.

[0024] Such an automatic cross-winding machine 1 generally also has a central control unit 37, which is connected to each winding head computer 39 of the windin...

Abstract

This invention relates to a method for rewinding the dyeing bobbin (4) onto a cross winding bobbin (11), wherein at the time of rewinding beginning and/or ending, the yarn (30) to unwrap from the dyeing bobbin (4) is unwrapped a defined length at a winding speed which is less than the winding speed arranged for the yarn (30) to rewind.

Description

Technical field [0001] The present invention relates to a method for rewinding dyed bobbins onto cross-wound bobbins according to the preamble of claim 1, and a textile for the production of cross-wound bobbins according to the preamble of claim 8 machine. Background technique [0002] From EP 0 787 674 A2, a method for rewinding a dyed bobbin onto a cross-wound bobbin is known, in which, after rewinding, a pre-set yarn length is removed from the cross-wound bobbin again. This is done against the background that the innermost and outermost layers of the dyeing bobbin may be unevenly dyed or have other unfavorable properties caused by the dyeing process. In order to prevent the innermost and outermost yarn layers wound on the dyeing bobbin from being left on the cross-winding bobbin to be produced, unwinding from the winding bobbin can be wound from the previous dyeing bobbin to the cross-winding with a preset length The innermost yarn layer on the bobbin and the outermost yarn la...
