Electronic control data transmission for knitting machines

摘要

A knitting machine comprises a stationary part and a rotary part, a data transmitter associated with the stationary part and a data receiver associated with the rotary part. The rotary part carries a photo-receiver either on its axis of rotation or arranged to follow a predetermined path as the rotary part rotates, said photo-receiver being connected to the data receiver. The stationary part carries a photo-emitter or a configuration of photo-emitters located so as to illuminate the photo-receiver or the path of the photo-receiver, the photo-emitter or photo-emitter configuration being connected to the data transmitter to illuminate the photo-receiver or the path of the photo-receiver with a train of light pulses corresponding to the data transmitted so that the photo-receiver produces a train of electrical pulses corresponding to the data transmitted.
