Abstract

An opening arrangement for an open-end spinning device with a rotating opening roller having opening elements stationarily arranged on its circumference for opening a delivered sliver into individual fibers and for combing out the fibers at a comb-out point. The opening roller has a mechanical stripping arrangement that rotates along with it. The stripping arrangement includes ejectors that are pivotably fastened on the opening roller. Each ejector is arranged between the opening elements and extends over the opening roller transversely in relation to the direction of rotation. The ejector strips combed-out fibers off the opening elements and improves the opening of the opening roller as well as the transfer of the fibers from the opening roller. The opening arrangement is advantageously employed with an open-end spinning frame.
