ABSTRACT:
A spinning unit of an open-end spinning machine comprising a spinning rotor to which separated fibers are supplied to be formed into a yarn which is withdrawn through a take-off duct and wound onto a bobbin. At its inlet end portion, the yarn take-off duct is rounded and embodied as an exchangeable funnel around which the yarn sweeps while it is given a false twist. In accordance with the invention the funnel and the body of the yarn take-off duct constitute a pair of members, the funnel being coupled with the body of said duct by magnetic coupling means so that funnels may readily be changed in accordance with the requirements of various fibrous materials to be processed by the spinning unit.
