ABSTRACT:
With channels for the conveying of fibers, fiber slivers or yarns on spinning machines, problems are encountered in their manufacture. The channels must be made with a certain inside contour, where at the same time the quality of the surface inside the channel must be very good. The high surface quality is required in order to ensure trouble-free conveying. A channel is therefore proposed which is made as a tubular component, consisting of a metallic material and which has been produced by forming its interior by a medium under pressure. It is proposed for an open-end rotor spinning device to form the conveying channel separately from the other components of the lid of the rotor housing and to insert the channel into the lid. It is proposed in that case to use a channel according to the design shown above.
