发明名称 Yarn draw-off nozzle with a funnel-like yarn entry for an open-end spinning machine and process for producing the yarn draw-off nozzle
摘要 To achieve better spinning results, in a yarn draw-off nozzle (1'), of the parts coming in contact with the yarn (15), at least the funnel-like yarn entry (12') is provided with a multiplicity of erosion craters. This is carried out by means of a spark-erosion machine or by means of a periodically interrupted blast (26) of high-energy particles. In addition, the yarn draw-off nozzle (1') can have a surface coating or a surface layer (18). <IMAGE>
