Abstract (en)
[origin: WO2015124497A1] The invention relates to a device for crimping multifilament threads, comprising an injecting apparatus and a compressing apparatus. The injecting apparatus has a conveying channel having a thread inlet, wherein the conveying channel of the injecting apparatus leads into a compression chamber of the compressing apparatus. The compression chamber has a plurality of slot-shaped air outlet openings between a plurality of wall segments. According to the invention, in particular in order to prevent filaments from being drawn into the air outlet openings, the wall segments of the compression chamber each have a flow edge oriented tangentially to a chamber circle in order to form the air outlet openings.
