A rotary sinker enabling stitch formation by a knitting machine using a rotor for forming a stitch, a knitting machine including the rotary sinker, and a stitch forming method are provided. The ring sinkers as rotating bodies are capable of rotating about a rotation axis independently of each other. The rotation times of the ring sinkers are set to be different from each other. Thus, the rotation times are adjusted to be different between the ring sinker that holds an old loop and the ring sinker that holds a new loop. Adjustment of the rotation times prevents application of a large tension to the knitting yarn made of low stretch fiber, and a stitch can be formed even with a knitting yarn made of non-stretch or low-stretch fiber.

Rotary sinker, knitting machine, and stitch forming method

The present invention provides a rotary sinker capable of suppressing energy loss and achieving reduction in the driving load, a knitting machine provided with the rotary sinker, and a knitting machine control apparatus. The sinkercomprises a rotating bodythat can rotate about an axis, and supporting memberswhich rotatably support the rotating body. A circumference edge portion of the rotating bodyis provided with sinker teethformed of a plurality of projecting sections to which rotational drive force is transmitted and with which a knitting yarn can be engaged.

Rotary sinker, knitting machine and knitting machine control apparatus

The knitting element has a rotor capable of rotating about an axis and makes a knit stitch by using rotational motion of the rotor. The rotor is formed in a circular disk shape. A pair of bearing plates is separated from each other in a radial direction of the rotor. The rotor is supported rotatably by bearing plates support slidably the circumferential surface of the rotor. A plurality of teeth to which rotational drive force is transmitted is formed in a circumference edge portion of the rotor. An engagement recess capable of engaging knitting yarn is formed in the circumferential face of the rotor.

Knitting element comprising rotor and knitting machine

The knitting element has a rotor capable of rotating about an axis and makes a stitch by using rotational motion of the rotor. The knitting element has a rotor having a rotating shaft which protrudes in the direction of the axis and a bearing which slidably supports the circumferential face of the rotating shaft. An engagement recess capable of engaging knitting yarn is formed in the circumferential face of the rotor.
