ABSTRACT:
In order to prevent the dispersion of knitting patterns which otherwise might result from backward motion when a circular knitting machine stops, a phase condition memory unit is provided for storing the phase condition of a sine-wave signal from a needle track detector of the circular knitting machine before the sine-wave signal passes the zero level. On condition that an output is produced from the phase condition memory unit, a synchronizing signal obtained from a synchronizing signal detector is made effective.
