[origin: US5765399A] PCT No. PCT/EP94/03616 Sec. 371 Date Aug. 16, 1996 Sec. 102(e) Date Aug. 16, 1996 PCT Filed Nov. 3, 1994 PCT Pub. No. WO95/16628 PCT Pub. Date Jun. 22, 1995For determining the movement of a thread supply boundary on the storage surface of a thread storage and feed device, different scanning properties of at least two circumferentially offset circumferential sections of the storage surface are scanned simultaneously and converted into storage surface signals which are nonidentical among themselves and which are discriminated from thread signals which are identical among themselves. The thread signals are generated by sensors which scan a scanning zone on the storage surface and formed on the basis of a scanning property of the thread windings when the thread supply is present in the scanning zone. The thread storage and feed device is provided with first and second circumferential sections on the storage surface differing from one another with respect to their scanning properties, and a plurality of sensors. The sensors are spaced approximately in the circumferential direction of the storage body in such a way that at least a first circumferential section of the storage surface can be scanned by one sensor and, simultaneously, a second circumferential section of the storage surface can be scanned by at least one additional sensor.
