ABSTRACT:
A circular knitting machine having tiltable pattern jacks, intermediate jacks thereon and needles over the intermediate jacks, the pattern jacks having lower butts for being raised and lowered by substantially triangular cams rigid with a cam ring. The lowering portion of the cams has a curvilinear portion joining the lowering portion and having a radius of curvature which is smaller than the ideal radius of connection between the lowering portion and the horizontal portion of the cam ring between the cams. The curvilinear portion remains at a distance from a base plane of the cam ring substantially corresponding to the distance between the lower face of the lower butt of the pattern jacks and the lower face of the pattern jacks. The curvilinear portion is followed by a further descending portion. There is therefore provided a cam lowering portion having a rounded step which causes the pattern jacks to approach progressively to the base plane, thus avoiding a kick back of the pattern jacks which in known machines operating at high speed causes breakage of the butts of the intermediate jacks.
