ABSTRACT:
A method of separating fibers from a fibrous sliver and conveying them in this condition to a twist forming element of an open-end spinning unit. The fibers traverse a fiber separating zone which is formed by the annular space between a combing-out cylinder and the bore of a housing. Ambient air is sucked into this fiber separating zone as well as into a sliver feeding zone. The air being sucked in is the resultant of air flowing in planes perpendicular to the axis of the combing-out cylinder, in planes passing through said axis and in planes parallel to said axis.
The apparatus for carrying out the aforedescribed method which includes a housing with a bore, a combing-out cylinder coaxially mounted in the bore, a sliver feeding device mounted in a cavity of the housing adjacent to the combing-out cylinder, and a lid covering the housing, but at least the region of the sliver feeding device being at least partially exposed to permit ambient air to be sucked into the sliver feeding and fiber separating zones.
