Problems solved by technology

[0022] The overall rather cumbersome and cost-effective arrangement of an additional underlayment, which has to be deducted as a consumable after the dyeing process, has not been possible until now in the practice of producing dyeing cylinders

Embodiment Construction

[0040] exist figure 1 A textile machine for the production of cross-wound bobbins, in this embodiment an automatic winder, is schematically shown in side view, generally designated by the reference number 1 .

[0041] This form of automatic winder usually has a number of identical stations 2 between its end frames (not shown) where it is known but not specified in detail that the ring spinning Cops 9 produced by the machine are rewound into bulky cross-wound bobbins 11, which in this embodiment are rewound into dyeing bobbins.

[0042] After finishing the production of the cross-wound bobbins 11, for example, by rotating the creel 18 around the axis of rotation 19, they are transferred to a cross-wound bobbin-transfer device 21 as long as the machine and delivered to the An end (not shown) bobbin handling station or similar, from where it is handed over to the dyeing station.

[0043] Such an automatic winder 1 often has a logistics device in the form of a bobbin and bobbin tr...

Abstract

The invention relates to a method for manufacturing a dye bobbin in the form of a cross-wound spool. According to the method, the cross-wound spool is supported in a bobbin creel of a coil winder of an automatic winder by utilization of a spool. The coil winder is provided with a device for rotating the cross-wound spool, and a device for allowing transverse movement of the yarn wound on the surface of the cross-wound spool. A random winding manner is adopted at the beginning of the dye bobbin (11) for winding, wherein inner yarn layers are wound with a large first cross angle (alpha) for producing good dye liquor, and the spool is switched to a small second cross angle (alpha 1) when reaching of a predetermined diameter (d) of the dye bobbin (11) and rewound in a random winding manner.

Description

technical field [0001] The invention relates to a method of manufacturing a dyeing cylinder formed as a cross-wound bobbin. Background technique [0002] It is known that cross-wound bobbins are often produced using so-called automatic winders. This means that at the stations of this type of textile machine very small volume bobbins, for example bobbins produced on ring spinning machines, are rewound into large volume cross-wound bobbins in which, During the rewinding of the yarn, yarn irregularities are also checked and yarn faults are removed. [0003] In order to be able to further process such cross-wound bobbins in an orderly manner in the subsequent work process, in addition, the cross-wound bobbins must also have good unwinding characteristics, for example, when producing cross-wound bobbins The way in which the yarn is moved affects the unwinding characteristics. [0004] In the manner in which the yarn is moved, a distinction must be made between two types of win...
