ABSTRACT:
A sinker cam ring for a circular knitting machine comprises a plurality of sinker cam segments arranged edge-to-edge to form the sinker cam ring, each sinker cam segment defining a portion of a sinker cam track that defines sinker-advancing and sinker-retracting surfaces. Breaks between adjacent sinker cam segments are located in linear portions of at least one of the sinker-advancing surfaces and sinker-retracting surfaces where substantially only frictional forces act on the sinkers, and thus where radial acceleration of the sinkers caused by the cam surfaces is substantially zero. The breaks for a given sinker cam segment can be circumferentially staggered relative to each other.
