Problems solved by technology

[0009] This means that the major disadvantage of these known waxing devices is that only one type of wax body can always be processed by means of these devices—either small or large wax bodies, these wax bodies are especially in their receiving area. The cross-sectional aspects of the openings are different from each other
When it is desired or necessary to change the size of the wax body, at present it is always only possible to replace the entire waxing unit

Embodiment Construction

[0033] figure 1 A station 1 of an open-end rotor spinning machine is shown schematically in which a waxing device 5 is used. As is known per se, such a station 1 in each case has an open-end rotor spinning unit 2 for producing yarn 3 and a winding device 12 for producing cross-wound bobbins 8 . The yarn 3 produced here in the open-end rotor spinning group 2 is drawn off from the same by means of a yarn take-off device 4 , which can be driven by a separate motor, for example, from which the yarn 3 is on its way to the winding device 12 . The path also passes through a waxing device 5 constructed according to the invention.

[0034] As is also known, the winding device 12 has a creel 9 , a yarn traversing device 6 and a cross-winding bobbin drive roller 7 .

[0035] The present exemplary embodiment shows a conical cross-wound bobbin 8 , which is rotatably supported in a creel 9 , which itself is connected to the station housing 11 at least via a pivot axis 10 . .

Abstract

The invention relates to a paraffin-treatment device (5) for a workstation (1) on a textile machine producing cross-wound bobbins, having a drive and bearing shaft (13) that can be rotationally movedand on which a paraffin body (14) is supported in a rotationally fixed, but axially displaceable manner, having a receiving opening (23) in the region of the central longitudinal axis (35) thereof. According to the invention, in a first embodiment, the drive and bearing shaft (13) has a bearing region (27) designed such that a paraffin body (14) of a first type can be slid onto it, having a receiving opening (23) having a first cross section (A1), and that the bearing region (27) of the drive and bearing shaft (13) is expandable in the dimension thereof such that the expanded bearing region (27) can support a paraffin body (14A) of a second type, the receiving opening (23A) thereof having a second cross section (A2).

Description

technical field [0001] The present invention relates to a waxing device according to claim 1 or the preamble of claim 7 . Background technique [0002] Waxing devices have been known for a long time in connection with spinning machines for producing cross-wound bobbins, such as open-end rotor spinning machines, and are well described in numerous patent documents. [0003] This waxing device is mainly used to reduce the friction coefficient of the yarn. That is to say, the movement and sliding properties of the yarn can be significantly improved by the wax particles applied to the yarn, which are very important for subsequent processes such as weaving or knitting. [0004] In order to consume the wax body as uniformly as possible during wax application, in known waxing devices, the wax body is generally rotated slowly about its central longitudinal axis, with the moving yarn against the end faces of the wax body. [0005] In German patent DE 40 10 469 A1, for example, a wax...
