Description

Technical Field

[0001] The present invention relates to the technical field of flat knitting machines, and particularly to a needle bed component for knitting ready-to-wear on a flat knitting machine. Background Art

[0002] Constrained by factors such as the pattern making of sweater knitting technology, the mechanical motion control system, and the pioneering design of main components, the knitting of sweaters has always remained at the stage of knitting separate pieces such as the front and back pieces, two sleeve pieces, and the collar. It becomes a complete sweater only after being sewn by hand on a dedicated sweater sewing machine. The sewing process is a labor-intensive process that is time-consuming and laborious.

[0003] With the improvement of knitting pattern making, the enhancement of the control system, and the gradual maturity of the industry's pioneering design, wide-width computerized knitting flat knitting machines with medium-thick 7 - 9 needles / 25.4 mm (number of latch needles per inch) and medium-thick needle gauge with alternate needle knitting (such as: 7 needles for a 14-needle plate with a large width to achieve the actual number of needles required for a sweater) have been introduced to the market. However, for medium-fine needle gauges such as 11 - 14 needles, restricted by equipment such as latch needles, when using and installing latch needles in the traditional way, the thickness of the latch needle is below 0.5, the needle hook is too small, and the yarn content is not up to standard. The suspended loop tightened unilaterally bends the extension rod of the needle hook, making it impossible to use alternate needle ready-to-wear knitting.

[0004] After 2000, internationally famous brands in the industry launched multi-needle bed flat knitting machines - a main knitting four-needle bed flat knitting machine with an overlapping front and back needle bed, and configured with a needle selection type pressure-assisted needle bed, which perfectly achieved ready-to-wear knitting with a fine needle gauge of more than 12 needles. It uses complex dedicated composite latch needles, needle beds, and composite three-dimensional triangular tracks, and the single unit price is as high as over one million, which is about 20 times the price of existing domestic computerized knitting machines. Sweater enterprises simply cannot afford it, but the demand for the localization of ready-to-wear knitting computerized knitting machines with medium-fine needle gauges is extremely urgent. Summary of the Invention

[0005] In view of the above problems, the invention provides a needle bed component for knitting ready-to-wear on a flat knitting machine, so that the thickness of the latch needle and the yarn content of the needle hook meet the requirements for knitting medium-fine gauge sweater ready-to-wear, without changing the movement trajectory and needle selection method of the latch needles of the existing flat knitting machine.
