Embodiment Construction

[0045] figure 1 A side view of a winding spindle of a textile machine for producing cross-wound bobbins, generally designated by the reference numeral 22, is shown.

[0046] Such textile machines, above all automatic winders, usually have a number of working spindle positions 1 arranged in a row.

[0047] Yarn feed bobbins 2, usually bobbins produced, for example, by a ring spinning machine (not shown), are wound on these working spindles 1 into high-capacity cross-wound bobbins 13 .

[0048] For this purpose, the working position 1 is equipped with various known, and therefore only schematically represented, yarn handling devices and detection devices, which are each defined by the working position's own control device, a so-called winding position computer 5. control.

[0049] The yarn 3 unwound from the yarn feeding bobbin 2 is at first passed through the yarn unwinding device 4 according to the present invention, runs to the cross-winding bobbin 13 according to its yarn ...

Abstract

A cross-wound bobbin rests on an upright spindle and surrenders its thread as this is drawn off horizontally to a textile machine. The thread discharges first horizontally to a pulley wheel (23) that is spring-mounted on a horizontal arm. The arm rises and falls to maintain horizontal discharge of the thread from the bobbin. The pulley wheel is maintained at all times below the highest point of the bobbin. Thread discharge speed variations are minimized by horizontal variation of the gap (a) between the pulley and bobbin axis (33). The pulley arm (24) end rises and falls (29) in a groove (31) under power.

Description

technical field [0001] The invention relates to a winding spindle for producing cross-wound bobbin textile machines. Background technique [0002] On the winding spindle of this textile machine, many yarn feed bobbins, especially cops with less yarn capacity produced by ring spinning machines, are wound into cross-wound bobbins of large packages. [0003] In addition, during the winding process, a yarn defect in the sliver is detected, which is promptly cut off and spliced ​​almost the same as a normal yarn. During this winding process, the yarn can achieve varying degrees of yarn tensile strength. [0004] That is, during the unwinding process of a cop, if there are no effective measures, especially in the last third of the cop, the yarn tension can increase to many times the initial tension, which significantly increases the risk of yarn breakage. [0005] Yarn breaks not only negatively affect the quality of the cross-winding package, but also reduce the efficiency of t...
