Abstract (en)
[origin: EP0445554A2] In an open-end spinning machine, there is a yarn draw-off nozzle which is so designed that it has an especially high heat dissipation capacity. The yarn draw-off nozzle therefore has a basic body consisting of a thermally conductive material, to which the yarn-guiding surfaces made of wear-resistant material are attached. Various alloys are provided for the basic body.
