ABSTRACT:
A channel plate adapter24is provided for an open-end spinning arrangement1having a spinning rotor3which turns at a high number of revolutions inside a rotor housing2chargable with an underpressure. The channel plate adapter24is made of a plastic material, defines the orifice area of a fiber guide conduit and a center through-bore26for a yarn withdrawal nozzle27, and is adapted to be exchangeably arranged in a receiver22of a fiber channel plate10for closing the rotor housing during a spinning operation. The channel plate adapter (24) has a unitary one-piece clip-on closure (37) at inlet area of the through-bore (26) for centering and fixing the yarn withdrawal nozzle (27) in place.
