Embodiment Construction

[0080] figure 1 The front view schematically shows a textile machine, in the exemplary embodiment a winding machine, generally denoted by the reference number 1 for producing winding bobbins.

[0081] Such a winding machine 1 usually has a plurality of identical stations 2 between its (not shown) end frames, in which, as is known and therefore not described in detail, it will be produced, for example, on a ring spinning machine The spinning bobbin 9 is rewound into a large package cross-winding bobbin 15.

[0082] After production, the cross-wound bobbins 15 are handed over to a cross-wound bobbin conveyor 21 along the machine length by means of an automatically operating service unit, preferably (not shown) a cross-wound bobbin changer and sent to The bobbin loading station at the end side of the machine, etc.

[0083] Such a winding machine 1 usually also has a logistics device in the form of a bobbin conveying system 3 , in which spinning bobbins 9 or empty bobbins circul...

Abstract

The invention relates to a friction disc for a yarn connecting device for the knot-less connection of two thread ends, the friction discs being mounted rotatably relative to one another in order to exert a mechanical action on the thread ends to be connected and each comprising a support and a friction lining friction disc mounted on the support. According to the invention, one of the friction discs is formed in a multi-part manner and has an intermediate part, an inner ring and an outer ring which are mounted in an axially displace-able manner, the other friction discs are designed to have atleast one intermediate part and one ring, and at least one friction disc is associated with a friction lining which has at least two friction regions.

Description

technical field [0001] The invention relates to a friction disk for a yarn connecting device, a yarn connecting device comprising such a friction disk and a textile machine for producing winding bobbins comprising such a yarn connecting device. The invention also relates to a method of manufacturing such a friction disk for a yarn connecting device. Background technique [0002] In the textile industry, yarn joining devices have long been in the state of the art and are clearly described in numerous patent applications. The yarn joining device produces an almost yarn-like joining of the yarns by swirling or rotating the two yarn heads. Such a yarn connection is an important criterion for the yarn quality and should not only have a yarn-like strength, but should also have as far as possible a yarn-like appearance. [0003] When a yarn break occurs during processing on a textile machine for winding bobbins or when a prescribed cleaning and cutting is carried out at one of th...
