Abstract (en)
[origin: EP1318219A2] In a spinning process fibre runs at high-speed through a rotor housing maintained at low pressure and closed by a cap. The incoming staple fibres collect within the rotor groove, combine and twist in the binding-in-zone, and discharge as a yarn section (44) extending between the rotor groove and thread withdrawal jet. The yarn section is subject esp. to a pneumatic force (F) opposite to its direction of rotation (U). <??>The curved yarn section (44) is exposed to numerous surrounding array of tangential incoming air jets applying a twist force at an angle of between 10 and 30 to the yarn section (44). The yarn section (44) rotates at a distance of 0.5 to 1.5 mm from the surrounding air jets. Also claimed is a commensurate open-end spinning assembly.
