ABSTRACT:
A knitting machine provided with patterning mechanisms responsive to pattern-control signals is caused to produce a non-repeating pattern by generating the pattern-control signals randomly, using a random signal generator not operating in synchronism with machine operation and generating potential pattern-control signals, from which actual pattern-control signals are derived in synchronism with machine operation. Although the pattern-control pulses are randomly generated, the overall character of the pattern produced can be altered by adjustment of the random signal generator to thereby alter the probabilities in the random generation of potential pattern-control signals. Also, pattern restraints are imposed upon the randomly produced pattern-control signals in both the horizontal and vertical directions, involving the number of consecutive stitches of a certain type that are to be permitted to adjoin in one course and in one wale, this being selectable in a manner not detracting from randomness.
