Abstract
In an arrangement for application in open-end rotor spinning, an opening roller is housed in a swivel housing. The swivel housing can, together with the assembled opening roller, be removed from the arrangement for open-end rotor spinning when the machine is in operation. The opening roller, due to its mass, continues to rotate after it has been separated from the tangential belt which drives it. A locking device is provided which prevents the removal of the swivel housing when the opening roller is rotating. This results in the opening roller being at a standstill when the swivel housing is removed. The risk of injury caused by a still rotating opening roller is eliminated.
