ABSTRACT:
An arrangement for producing synchronization pulses for pattern control of the knitting needles of a circular knitting machine. The arrangement includes a plurality of control units mounted on, for example, the cam housing, which units coact with the butts of the knitting needles mounted on the needle cylinder. The number of control units per knitting system is equal to (n) which corresponds to the number of different types of selector elements. A raster system, forming part of a ring which rotates with the needle cylinder, coacts with a pick-up unit mounted on the cam housing. The pick-up unit includes a plurality of pick elements which emit signals in accordance with the scanning of the raster system. When the needle cylinder rotates normally, a series of code signals are cyclically produced and logically combined in the sense of a logic AND circuit by means of a read out control unit which ensures this cyclic sequence of signals even if the needle cylinder comes to a standstill or rotates slighly in a reverse direction.
