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 disadvantages in this method are the costs necessary for implementation and the decrease in productivity
In other words, this method reduces the number of winders available for rewinding the dyeing bobbin, while the control and operation of the textile machine becomes more expensive

Embodiment Construction

[0021] figure 1 Schematically represents a front view of a textile machine for producing cross-wound bobbins, namely an automatic cross-winder in this embodiment, which is generally designated by reference numeral 1 . The automatic cross-winder 1 has between its end frames 35 , 36 a number of work stations, so-called winders 2 .

[0022] as from figure 2 As can be seen in particular, the dyeing bobbin 4 is rewound on the winder 2 to form a cross-wound bobbin 11 . The finished dyeing bobbins 4 newly rewound to form cross-wound bobbins 11 are conveyed by an automated service unit, for example by means of a cross-wound bobbin changer 23, onto a conveying device 21 which takes the cross-wound bobbins 11 to a bobbin loading station (not shown) or the like arranged at the end of the machine.

[0023] Such an automatic crosswinder 1 generally also has a central control unit 37 which is connected, for example via a machine bus 40 , not only to the individual winder computers 39 of...

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 invention relates to a method for rewinding dye bobbins onto cross-wound bobbins on a textile machine with several winders; of textile machines. Background technique [0002] From EP 0 787 674 A2 a method is known for rewinding a dyeing bobbin onto a cross-winding bobbin, in which, after rewinding, a predeterminable yarn length is again removed from the cross-winding bobbin. This is done against the background that the innermost and outermost layers of the dyeing bobbin may be dyed unevenly or have other unfavorable properties due to the dyeing process. In order to avoid that the innermost and outermost yarn layers wound on the dyed bobbin remain on the cross-wound bobbin to be produced, a pre-set length of winding from the previous dyed bobbin to the cross-wound bobbin is unwound from the winding bobbin The innermost yarn layer on a bobbin and the outermost yarn layer subsequently wound from the next dyed bobbin. In this case, the unwound yarn ...
