ABSTRACT:
An open end spinning machine includes a plurality of spinning units, in each of which a sliver is opened by a carding roller and transported, in the form of individually opened fibers, into a spinning rotor through a fiber supply channel provided in a housing for the carding roller. The supply channel has a mouth opening towards the carding roller with a fiber separating edge, which is greatly subject to wear during operation of the spinning unit. A portion of the carding roller housing, which defines at least the fiber separating edge, is detachable from another portion of the housing and is urged in a predetermined direction by a biassing spring so that any undesirable clearance, which would be produced between the portions of the housing by structurally separating them from each other, can substantially removed.
