Beschreibung
Zusammenfassung:	FIELD: magnetic thread recognition means. ^ SUBSTANCE: method provides for relative movement between thread and matrix of magnetic heads; each head generates a signal in case of detection of a portion of thread. Approach of thread to one of heads is detected, while this head is marked as main head, and heads on each side of the latter - as secondary heads. Output signals from main and secondary heads are controlled for forming of an image of thread signals amplitudes from main and secondary heads are compared, so that if amplitude of output signal from secondary head exceeds amplitude of signal from main head, then secondary and primary heads are appropriately reassigned. ^ EFFECT: higher speed of operation, higher efficiency. ^ 6 cl, 17 dwg
