<p>The system for inducing unwanned carrier comprises an inducing lines (1,1a,1b) having inducing marks (M) at intervals (d,d1,d2). The carrier (2) counts the inducing marks (M) to find it present position. The running speed of the carrier (2) is found find by calculating the present position in relation to counting of pulses generated from a clock.</p> |
