Abstract
In order to permit an open-end spinning unit to be opened with a relatively small amount of force, there is a swivel lid which covers all parts, without these parts being attached thereto. However in order to enable the opener roller to be stopped when the open-end spinning unit is opened, the opener roller is located in a swivel housing, which swivels when the lid is opened, thereby interrupting the drive of the opener roller, as a wharve of the opener roller lifts away from a tangential belt.
