I have a Toyota KS901 knitting machine and a KR501 ribber. Is it possible to do tubular knitting on these machines to include punch card patterning. I understand that the ribber has no pattern facility but thought maybe it is possible to do patterning on the main bed so that I get a tube with patterning on one side. Trouble is, I seem to have tried every combination of the cam set levers on the main bed but always the knitting reverts to a single knitted piece. Am I missing something or is it not possible. Any help would be greatly appreciated.
