  • Publication number: 20040083766
    Abstract: In a process of knitting a fabric during which at least a part of loops in the flechage knitting region are transferred between the front and back needle beds to move the loops laterally, loops in a stitch move region which are moved laterally whenever an adequate number of courses of the flechage knitting region are knitted are transferred to an opposite needle bed and then the front and back needle beds are moved relative to each other. Then, loops of wale which are put in the rest state in a process of the flechage knitting are held on the needle bed opposite to the needle bed on which loops of a next course are formed in a sequent flechage knitting until the stitch move is completed. Only the loops of the wale in which the loops of the next course are formed in the sequent knitting are transferred back to their originally retained needle bed prior to the forming of the loops of the next course. This knitting is repeatedly performed.

  • Publication number: 20040065123
    Abstract: A knitting method of joining together adjacent fabrics (3, 5), which are arranged side by side and knitted in a tubular form, at ends thereof on the sides adjacent to each other by using a flat knitting machine so that the joining portion of knitwear, such as a side part of sweater or at a crotch of pants, is prevented from being holed and is also increased in pull strength. The knitting progresses from one of the tubular knitted fabrics (3) to the other tubular knitted fabric (5) to join together the tubular fabrics, during which a yarn is fed to needles holding loops formed one stitch backward with respect to a join processing direction to provide a tubular knitting for the needles, followed by shifting the yarn to needles holding loops formed two stitches forward with respect to the join processing direction, to provide the same tubular knitting as above for the needles, the knitting steps being repeatedly performed.

  • Patent number: 6658898
    Abstract: At least three bind-off courses are formed starting at not less than three loops, i.e., loops of the first and second knitted fabrics at side ends thereof on the side on which the knitting of a tubular fabric is finished in the region of the binding-off process, and a loop adjoining to the loop of at least either of the first and second knitted fabrics at the side end. The loop of the bind-off course formed is laid over the loop of the last course of the opposite knitted fabric in such a manner that while being formed, the respective bind-off courses can be allowed to extend in zigzag from the first knitted fabric to the second knitted fabric and vice versa, ranging over the region of the binding-off process, to be crossed with each other. As a result of this knitting, no undesirable gap is produced between the joined knitted fabrics and also an undesirable stretch of the fabric at the joints is suppressed.

  • Patent number: 6578389
    Abstract: A knitting method for disposing an unused yarn edge produced in yarn-in or a yarn-out operation. The knitting method includes forming that two or more unused-yarn-edge disposal loops are from the knitting yarn introduced in and/or drawn out in knitting a knitted fabric by using an empty needle around an end side of a knitted fabric body; and moving the unused-yarn-edge disposal loops thus formed and laying each disposal loop over loops of different courses of the knitted fabric body located at an end side thereof in knitting the next course of the knitted fabric body. This knitting method allows the unused yarn edge to be held in the knitted fabric by the loops of the knitted fabric, and as such can allow the unused yarn edge to be disposed by simply cutting it at its portion close to the knitted fabric, without the need of the linking.

  • Patent number: 6550284
    Abstract: Knitting of a knitted fabric having a forked portion which is forked into a first knitting region and a second knitting region at a certain point of its knitting width by using a flat knitting machine including at least two yarn feeders arranged over needle beds. Prior to the knitted fabric being forked, a pair of right and left widening stitch loops that confront each other across the forked portion are formed at the back side of the knitted fabric during a course knitting of the knitted fabric, first, and, then, two groups of stitch loops, consisting of a pair of right and left stitch loops that are formed at a front side of the knitted fabric and confront each other across the forked portion and a pair of right and left widening stitch loops that are newly formed, are crossed to each other across a boundary of the forked portion. This can provide enhanced strength for the forked portion without impairing the appearance of the knitted fabric.
