Abstract
A sinker includes a sliding segment with a sliding portion slidably located in a sinker groove, a loop forming and loosening ancillary segment extended upwards from one side of the sliding portion and then extended outwards, a passive segment located above the sliding segment and driven by a cam, and an indented abrasion-reducing space located at a lateral side of the sliding portion and below the loop forming and loosening ancillary segment. Through the abrasion-reducing space, the loop forming and loosening ancillary segment can move directly and horizontally above a needle cylinder. The loop forming and loosening mechanism for circular knitting machines of the invention can simplify fabrication of the needle cylinder, reduce labor and material costs, improve quality and production yield of the needle cylinder, and also reduce abrasion of the sinker, thus can improve performance of the mechanism and enhance lifespan of the sinker.
