ABSTRACT:
The method for monitoring the operative position data of each of a plurality of independent separately operable knitting machines and transferring such information to the address input of a common memory control system for controlling the patterning of each machine, is obtained by generating a pick-up pulse at each machine indicative of the passage of its needles and of the completion of each course past a given point. A continuous cycle of timing pulses each of which corresponds to a selected knitting machine for which data is to be monitored is provided. In response to each of the individual timing pulses the respective generated pick-up pulses are fed to a logic control sweep circuit, the output of which is fed to one input of an adding circuit. Simultaneously a second input is fed to the adding circuit comprising the position data information of the immediately preceding needle and course, which had been stored in a random access memory unit corresponding to the particularly monitored machine. The combined output of the adding circuit is simultaneously fed to the address input of the common memory control system for operation of the monitored knitting machine and to the input of the random access memory for storage therein for use in the next monitoring cycle.
