  • Patent number: 7582048
    Abstract: A fabric folding machine structure is used for receiving and folding a fabric woven by a circular knitting machine. A fabric folding machine is added to the circular knitting machine without changing the length, width, and height of the fabric rolling machine. The fabric folding machine has a carrying base for carrying the fabric, and both ends of the carrying base are fixed to the bottom of two side seats, and a plurality of fabric rolling rods disposed between the two side seats define a carrying space, and the two side seats include a fabric folding unit for driving the fabric on the carrying base, and the fabric folding unit can drive the fabric back and forth in the carrying space to fold the fabric on the carrying base, so as to provide a larger carrying space and a higher fabric storing capacity than a prior art fabric folding machine.

  • Patent number: 5515697
    Abstract: A rib jacquard knitting machine including dial needles arranged on the dial, cylinder needles arranged on the needle cylinder to knit loops with the dial needles, transfer needles and pelerine needles respectively arranged on the needle cylinder to make transfer stitches and eyelet stitches. A knit selector selectively drives the pelerine needles and the transfer needles into operative positions.

  • Patent number: 5501085
    Abstract: A fabric holding-down sinker for a double knit machine to stop the knitted fabric from being lifted during the raising stitch of the cylinder needles. A series of such presser sinkers are reciprocated radially relative to the cylinder needles, each presser sinker having a projecting sinker head horizontally disposed at a front end. The projecting sinker head is moved to a front limit position spaced above a topmost edge of a fabric formation surface of the knitting machine at a distance equal to the thickness of the fabric being knitted during the raising stitch of the respective cylinder needle, preventing the knitted fabric from being lifted by the cylinder needles.

  • Patent number: 5386711
    Abstract: A double knit machine which includes a series of sinker assemblies disposed corresponding to the cylinder needles of the machine for holding down the knitted fabric during the raising stitch of the cylinder needles, each sinker assembly comprised of a fixed sinker having a sinker rib for guiding out the knitted fabric, and a presser sinker reciprocated by the cam drive of the machine, the presser sinker being moved forward to press the knitted fabric against the sinker rib of the respective fixed sinker as the respective cylinder needle is extended out, or moved backward to release from the knitted fabric as the respective cylinder needle is received back.
