  • Publication number: 20240158964
    Abstract: Disclosed are a tension adjustment method of a warp knitting variable-speed and uniform-tension yarn feeding device, and a weaving method. The device includes warp beams, connecting rod frames, a guide bar, a looping mechanism and a drawing and rolling-up mechanism, where the connecting rod frames are connected to yarn winding wheels and yarn guide plates, yarns are wound on the warp beams, and the yarn winding wheels are positioned between the warp beams and the guide bar; each of the yarn winding wheels includes a yarn inlet, a yarn winding shaft and a yarn outlet. According to the present disclosure, the tension produced in a yarn feeding process is actively adjusted by the variable-speed tension yarn winding wheels to make up tension error caused by looping; and the present disclosure is capable of compensating in time, does not easily break the yarns, is high in knitting efficiency and quality.

  • Publication number: 20230383445
    Abstract: A tubular double-needle bed warp knitting machine includes a let-off mechanism, a knitting element, and a take-up and batching device. The knitting element includes guide needles in a circular pattern, two circular needle beds arranged internally and externally, knitting needles in a circular pattern along the internal and external needle beds, and knitting components that move in coordination with the knitting needles. Some of the guide needles form loops on the internal and external circular needle beds, while other guide needles alternately form loops on the internal and external circular needle beds to connect sections of the two fabric pieces to create a three-dimensional tubular fabric. The formed three-dimensional tubular fabric exits the knitting area through the traction of the take-up and batching device.
