A circular knitting machine for knitting a pile fabric with short stitch length, the circular knitting machine includes a needle dial, a needle bed, a gap formed by the needle dial and the needle bed, knitting needles on the needle dial, crochet needles on the needle bed, a cutter holder, and cutters on the cutter holder and facing the gap. Movement tracks of the crochet needles are crisscrossed with movement tracks of the knitting needles and movement tracks of the cutters. Each of the crochet needles has a butt portion, a hook portion, and a protruding shoulder portion between the butt portion and the hook portion, the protruding shoulder portion forms an eyelet, and the protruding shoulder portion is configured to be capable of expanding a yarn loop on the crochet needles to facilitate the cutters to cut the yarn loop at the eyelet to form a pile.

A knitting tool (10), preferably a latch needle, intended for fast-running knitting machines has a meandering shaft with reduced-thickness regions. The meandering shaft is adjoined by a straight shaft extension (16) which likewise has a reduced-thickness portion (32). The shaft extension (16) is distinguished from the shaft (15) by way of its height H2, which is less than the height H1 of the shaft (15). The reduced-thickness region (32) of the shaft extension (16) has a length which is at least much greater than the length of the stitch-forming structure (28) carried by the shaft extension (16). Preferably, the reduced-thickness region (32) is longer overall than the non-reduced-thickness region of the shaft extension (16). With this configuration, a surprisingly efficient high-speed-compatible knitting tool (10) is created.

A knitting action parts structure comprises a channel space, a needle walls assembly, a cams assembly, and knitting tools. The knitting tools are positioned within the needle walls assembly, facing the cams assembly to form the channel space. At least one cams assembly part faces a needle walls assembly part and a knitting tools part to form a gradually expanding channel spaces part. During the manufacturing of these parts, product quality is improved without the requirement for additional equipment or complex procedures. When producing fabrics with knitting machines, it prevents fabric contamination and optimizes heat dissipation performance without the requirement for additional energy-consuming devices, thus reducing waste caused by defective products and extending the lifespan of related parts.

Aspects herein are directed to a tensioning device for a strand on a knitting machine. The tensioning device includes a mounting plate that may be positioned between a strand source and a feeder bar. The mounting plate supports a first pulley, a second pulley and a weighted third pulley that is movable with respect to the first pulley and the second pulley. By routing a strand over the first pulley, under the third pulley and over the second pulley, additional tension may be added to the strand through the weight of the third pulley.
