ABSTRACT:
A fiber sliver opening roll of an open-end spinning device is equipped with needles, wherein the needle shaft of each needle is mounted in a bore. The surface of the opening roll is provided with outer, wide recesses which clear or leave free the needles at all sides. Below the bases of the recesses there are located the aforementioned bores which are smaller than the recesses. Between each needle and the side wall of the related recess there is left free a clearance or space. The depth of each recess is greater than the distance at the recess base between the outer surface of the needle and the inner wall of the recess, and which depth amounts to from 1 to 10 times the aforementioned distance. Owing to the provision of each such recess the related needle extends free on all sides between the roll surface and the bore in such a manner that there are prevented fiber jamming and fiber accumulations on the needles.
