Definitions

  • the present invention relates to a stitch increasing method for increasing the number of stitches in the course of knitting a fabric.
  • a known weft knitting machine including at least a pair of front and rear needle beds having a plurality of latch needles each having a hook configured to be opened and closed along with a pivotal movement of a latch and being capable of advancing and retracting in a sliding movement, the pair of front and rear needle beds being provided in a state in which teeth are positioned in proximity, and being capable of moving relatively in the lateral direction.
  • weft knitting machine of a type having a plurality of compound needles each having a hook configured to be opened and closed along with a sliding movement of a slide In the weft knitting machine of this type, increase of the number of stitches is achieved without a supply of yarn by allowing a stitch yarned over a hook of a compound needle on one of the front and rear needle beds to be yarned over a hook of a compound needle on the other needle bed by operating a slider of the compound needle on the other needle bed simultaneously with the advancement of the compound needle on the other needle bed (for example see Japanese Unexamined Patent Application Publication No. 3 ⁇ 279448 ).
  • the present invention is based on a stitch increasing method configured to increase the number of stitches by allowing a stitch yarned over a latch needle on one of front and rear needle beds to be yarned over a hook of the latch needle by advancing a latch needle on the other needle bed using a weft knitting machine including at least a pair of front and rear needle beds having a plurality of latch needles each having a hook configured to be opened and closed along with a pivotal movement of a latch and being capable of advancing and retracting in a sliding movement, the front and rear needle beds being provided in a state in which teeth are positioned in proximity, and being capable of moving relatively in the lateral direction.
  • the method includes advancing the latch needle on the one of the needle beds over which the stitch is yarned in the hook until the stitch moves out of the hook beyond the latch, and advancing the latch needle on the other needle bed to yarn the stitch moved out of the hook of the latch needle on the one of the needle beds over the hook of the latch needle.
  • the method includes subsequently, retracting the latch needle to a retracted position in a state in which the stitch is yarned over the hook of the latch needle on the other needle bed when retracting the latch needles on the front and rear needle beds while stopping the retraction of the latch needle at its mid position so that the stitch moving in association with retraction of the latch needle of the one needle bed is maintained in a state of being yarned over the latch needle on the outside of the hook without moving beyond the latch, thereby yarning the stitch over the latch needles on the front and rear needle beds respectively and increasing the number of the stitch.
  • the method subsequently includes advancing the latch needle on the one needle bed from its mid position and continuing a knitting operation for the stitch yarned over the latch needle on the outside of the hook.
  • the knitting operation may include an operation of transferring the stitch yarned over the latch needle on the one needle bed on the outside of the hook to the free needle on the other needle bed by advancing a free needle on the other needle bed when advancing the latch needle on the one needle bed from its mid position.
  • the knitting operation may include an operation of newly supplying a knitting yarn when the latch needle on the one needle bed is advanced from its mid position, then retracting the latch needle to yarn the knitting yarn over the hook, knocking over the stitch yarned over the latch needle on the outside of the hook, and forming a new stitch on the hook continuing from the knocked over stitch.
  • the stitch increasing method in the invention by stopping the retraction of the latch needle on one of the needle beds at its mid position so as to maintain the stitch doubled on the hook of the latch needle on the one needle bed to increase the number of stitches and yarned over the latch needle on the other needle bed on the outside of the hook to be kept in a state of being yarned over the outside of the hook without moving beyond the latch even when moving toward the advancing side relatively in associate of the retraction of the latch needle on the one needle bed, the number of the stitches can be increased without being accompanied with the supply of yarn using the latch needle in the same manner as a compound needle.
  • the operation of transferring a stitch yarned over the latch needle on the one needle bed on the outside of the hook to the free needle on the other needle bed by advancing the free needle on the other needle bed when advancing the latch needle on the one needle bed from its mid position can be performed continuously subsequent to the increasing operation.
  • the operation of newly supplying a knitting yarn from the yarn supply port when the latch needle on the one needle bed is advanced from its mid position, then retracting the latch needle to yarn the newly supplied knitting yarn over the hook of the latch needle, knocking over the stitch yarned over the latch needle on the outside of the hook, and forming a new stitch on the hook continuing from the knocked over stitch can be performed subsequently to the increasing operation.
