Suction nozzle for a workstation of a textile machine which produces crosswound bobbins

摘要

The suction nozzle has a suction port for the pneumatic picking of a yarn breakage or a controlled thread cut accumulated on the surface of a cross-wound bobbin end. The suction port is provided with a comb strip for fixing the bobbin end. The comb strip is produced by a photo-chemical etching process and formed with large and small teeth (20,21) of different heights. The distance between the large teeth is 0.5-1.0 mm.
