Abstract (en)
[origin: EP0712947A2] An open-end spinner has a rotor (11) with a rim (113) which extends from the opening (111) to the fibre collecting groove (112). An extension (3) which projects into the rotor has a yarn draw-off hole (33) and a fibre feed channel (31) with an impact surface (32) essentially at right angles to the feed channel. The impact surface (32) is arranged so that the fibres pass along it to the fibre collecting groove (112) or the rim (113) with a distance of less than 5.5 mm from the fibre collecting groove. Also claimed is a spinning rotor with a distance of less than 7 mm between the fibre collecting groove (112) and the opening (111), a fibre groove (112) dia. of less than 35 mm. and an opening (111) at least 84% of the fibre groove dia..
