ABSTRACT:
A cam mechanism for a circular knitting machine includes stitch cams each of which is provided with main cam wall sections adapted to control the position of each descending needle after its operating butt has come into contact on its upper side with the one of the main cam wall sections. The stitch cam is also formed with auxiliary cam wall sections of substantially the same contours as the main ones for guiding the needle on the underside of either the same or another operating butt to permit smooth movement of the needle while the operating butt is being controlled by the main cam wall sections. The two cam wall sections cooperate to guide the needles without irregular motion of their butts or needle points.
