ABSTRACT:
In the recess of a housing (4) of an open-end spinning device containing a driven opener roller (40), an insertion piece (32) is provided which contains the first channel part (30) of a fiber feeding channel. The insertion piece (32) is installed in housing (4) by an elastic retaining element in such a manner as to be replaceable. The retaining element may be part of a catch and be formed for this purpose by a ring or pot-like insert (43) which lines the interior of the housing (4) containing the opener roller (40) and which has technologically necessary openings (430, 432, 431) in its circumferential wall. The edges of the lateral walls of the first channel part (30) towards the ring or pot-shaped insert are adapted to the curvature of the insert (43). These lateral walls extend, relative to a perpendicular dropped from the center of the insert (43) on the longitudinal axis of the insertion piece (32), up to the side of the perpendicular (323) away from the spinning element (10).
