Open end spinning assembly with an opener roll

摘要

Open-end spinning assembly apparatus including an opener roll disposed in and rotatably supported in a bearing carried by an opener roll housing, with the opener roll and roll housing being constructed together as a detachable structural unit so as to accommodate simple exchange of the opener roll and bearing assembly. In preferred embodiments, the opener roll housing is thrust onto a support shaft and held in position by means of a spring supported and carried by a cover plate for the spinning assembly. A supplementary spring is provided for rotatably biasing the opener roll housing toward a position away from driving engagement with a tangential belt whenever said cover plate for the spinning assembly is opened or removed.
