Abstract
A plurality of knitting machines are controlled from a central control device and a common patterning memory. Each knitting machine is provided with its own needle and course counters in which the needle position is determined. The single control device provides separate clock signals to the counters of each machine so that they may be individually switched to the patterning memory. Simutlaneously, the control device provides means by which the output from the memory is switched to the electromagnet controlling needle operation in synchronism with the needle counter.

Apparatus for individually controlling a plurality of knitting machines, each of which has needle selectors, means for actuating said needle selectors and means for counting both needles and courses for determining the needle position of each of said machines comprising a common patterning memory adapted to be read by a pulse from each of said needle and course counters and to provide a signal for operating each of said needle selector actuating means, a central control device, said central control device having means for providing pulses for the successive switching of said needle and course counters in each machine to said common patterning memory and for simultaneously switching the output of the common patterning memory to the associated needle selector actuating means of each selector at a speed synchronous with a signal from the needle counter corresponding to the passage of the needles in the associated machine.
A method for individually controlling a plurality of knitting machines, each of which has needle selectors, means for actuating said needle selectors and needle and course counters for determining the needle position of said machine, comprising furnishing a common patterning memory adapted to be read by pulses from each of said needle and course counters and to provide a signal for operating each of said needle selector activating means and a central control device providing pulse signals for the successive switching of each of said needle and course counters to said common memory and simultaneously switching the output of the patterning memory to associated needle selector actuating means at a speed synchronous with a pulse signal from the needle counter corresponding to the passage of the needles.
