ABSTRACT:
The control arrangement is used in conjunction with a textile machine at which a thread or a filament, respectively, supplied from a creel package is guided via a roll, around which it forms a plurality of windings, to a thread guide eyelet and to a ring spindle system. The invention aims at the reliable elimination of any danger of lap-up formation on the roll including the danger of lap-up formation caused by unwinding the thread from a take-up bobbin (unwinding "overhead" from the take-up bobbin). The control arrangement comprises a first thread severing element which severs the thread upstream from the roll, and a second thread severing element which severs the thread along the unwinding path between the roll and the take-up bobbin. The control arrangement further comprises a thread feeler which is designed with a slot and which can release the thread in a plane at substantially right angles to the roll axis of the roll, and a control device for activating the thread severing elements and the thread feeler.
