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.

Knitting element with rotor and knitting machine

To provide a sock with a performance that matches its purpose of use and seasonal requirements. To change the thickness and strength of different parts of the sock according to the load distribution on the sole and the impact that the different parts of the sock are subjected to when walking and running. Knitting structures of different thicknesses and airspace ratios, e.g., flat stitches P, short-terry stitches SP, long-terry stitches LP, mesh stitches M, short-terry stitches based on mesh stitches M-SP, long-terry stitches based on mesh stitches M-LP, short-terry stitches based on reinforced mesh stitches M-R-SP, long-terry stitches based on reinforced mesh stitches M-R-LP, short-terry stitches with reinforcement yarn R-SP and long-terry stitches with reinforcement yarn R-LP are distributed in different parts of the sock.

Socks of multi-stage pile structure

A circular knitting machine includes a cylinder spacedly provided with vertical slits on its overall circumference, and sinkers and knitting needles alternately mounted in every other slit of the cylinder. Each one of the sinkers is formed on its bottom side with a cutout so that a sinker selection jack moving up and down within the slit pushes the slant front edge of the cutout to move the sinker horizontally, or towards the center of the cylinder. With the structure, the movements of the sinker can be individually controlled to form a pile patterning and reversed patterning.
