Embodiment Construction

[0035] figure 1 A station 2 of a textile machine 1 for producing cross-wound bobbins, which in this exemplary embodiment is a so-called automatic cross-winding device, is shown schematically in side view. As is known, such automatic cross-winding devices 1 each have a plurality of identically constructed stations 2 between their (not shown) end frames. Also as known without further explanation, at these stations 2 the spinning bobbins 3 produced on the ring spinning machine are rewound into large package cross-wound bobbins 5, which are After it has been produced, it is transferred by means of a service unit (not shown) such as a cross-wound bobbin changer to a cross-wound bobbin conveyor 7 arranged in the longitudinal direction of the machine and then to a bobbin delivery station arranged at the end of the machine Wait.

[0036] Furthermore, such an automatic crosswinder 1 usually also has a supply device in the form of a bobbin and sleeve transport system 6 . In this bobb...

Abstract

The finger thread guide unit (13) comprises an elongated base body (17) made of plastic with abrasion resistant thread guide elements (42,43) at its free end that traverse a thread running on the surface of a cross-wound spool during the winding operation. The carbon fiber rods (44,45) extending along the length of the base body(17) and a fastening and locking element (19) are molded in the base body, where the abrasion resistant protective units are oxide-ceramic tubes or chrome-plated steel tubes, which are partially molded in the base body.

Description

technical field [0001] The invention relates to a finger guide according to the preamble of claim 1 . Background technique [0002] Finger guides for yarn traversing devices of stations of textile machines producing cross-wound bobbins are known, for example in WO 00 / 24663, DE 102005059028A1 or DE 102008053261A1, which have been described in relative detail. [0003] For example, WO 00 / 24663 describes a finger-shaped thread guide which has a relatively small overall thickness in order to keep the mass as low as possible. Here, the yarn guide has at its free end a yarn guide for picking up and guiding the yarn to be laid, wherein the rounding and chamfering of the yarn guide are additionally processed to reduce the Abrasion that occurs between the yarn and the finger guides during the process. In addition, the guide forks have a surface coating whose coating material is characterized by relatively low friction and high wear resistance. [0004] However, the known finger gu...
