Abstract
Input pulses generated by rotation of a knitting machine are used to produce output pulses that energize needle selection mechanisms therein. A control system operates in such a fashion as to advance the output pulses with respect to the input pulses, while keeping pulse frequency constant. The control system is clocked, and a forward counter is programmed with a number which is dependent upon knitting machine speed, and which number is derived from the number of clock pulses intervening between subsequent input pulses. After the forward counter has been so programmed, it is clocked by the clock until the appropriate number of clock pulses has been counted. At that time, a pulse is generated by reverse counter and a monostable multivibrator, which is used to produce an output pulse according to a program stored in a PROM. Provision is made to bypass the counter when the knitting machine is operated at low speeds.
