<p>Upon determining the movement of a thread supply boundary on the storage surface of a storage body 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, said thread signals originating from the same sensors and being formed on the basis of the scanning property of the thread windings when the thread supply is present in the scanning zone. A thread storage and feed device (F) which is suitable for carrying out said method has provided thereon first and second circumferential sections (8, 9) of the storage surface which differ from one another with respect to their scanning properties (A, B) and a plurality of sensors (SA, SB, S) which are spaced approximately in the circumferential direction of the storage body (1) in such a way that at least a first circumferential section (8) of the storage surface can be scanned by one sensor and that, simultaneously, a second circumferential section (9) of the storage surface can be scanned by at least one additional sensor.</p> |
