  • Patent number: 7640770
    Abstract: In one embodiment of the present application, a knitting method is disclosed for a knitting fabric capable of eliminating the need of stitch transfer during knitting and easily knitting even a thick and less stretchable knitting fabric. Three types of stitching including knits marked with “O,” tacks marked with “V,” and missings marked with “-” are knitted repeatedly in a course direction and a wale direction. The thickness of the clothing fabric of a knitted product is 1.5 times that by plain knitting or thicker which is equal to a thickness obtained by rib knitting. The elongation of the knitted product in the course direction is approximately 1.5 times that by the other methods which is approximately half an elongation obtained by plain knitting which is approximately three times that by the other methods. The elongation of the knitted product in the wale direction is approximately 1.7 to 1.8 times that obtained by the other methods which is equal to an elongation obtained by plain knitting.

  • Patent number: 7269975
    Abstract: On each of carriages are disposed a group of transfer cams and a group of receiving cams. A leftward movement of the carriages makes it possible to transfer a knitted loop from a front needle bed provided with one carnage to a rear needle bed provided with another carriage. A rightward movement of the carriages makes it possible to transfer the knitted loop from the rear needle bed provided with the other carriage to the front needle bed provided with one carriage. The transferring can be freely carried out between the needle beds, and it is possible to temporarily place a knitted loop from one needle bed to another needle bed and keep a holding, and further retain the knitted loop separately from a fabric being knitted on the other needle bed and when needed, return the knitted loop from the other needle bed to the one needle bed.

  • Patent number: 7269976
    Abstract: A yarn feeder can be stopped at a stopping mechanism and attached to and detached from a holder. The holder is fitted to a front end of a holding arm. The carriage-side holding arm is held by a moving member holding mechanism. The moving member holding mechanism includes a bringing state switching mechanism to switch the bringing state of the moving member by the carriage. The bringing state switching mechanism acts on a coupling portion on the carriage side, and can shift the bringing position of the moving member holding mechanism relative to the carriage and perform the switching to a position where the moving member holding mechanism is not brought. A rail is provided such that the yarn feeder's position does not change even when the moving member holding mechanism is separated from the carriage. The rail is installed to be parallel with a needle bed's longitudinal direction.

  • Patent number: 7216513
    Abstract: A permanent magnet applies first sliding resistance in-between a holding arm and a guide rail. A carriage is provided with an electromagnet for magnetically applying second sliding resistance in-between the holding arm and the carriage. Although the holding arm persists in moving through inertia when the carriage stops movement, a sliding resistance that is the sum of the first sliding resistance and the second sliding resistance acts on the holding arm, and it is possible to promptly stop. Since the second sliding resistance does not act when the carriage brings the holding member, it is possible to reduce a load. When the carriage starts bringing the holding arm, a difference between the first sliding resistance and the second sliding resistance becomes the sliding resistance, and it is possible to decrease sliding resistance that acts when bringing is started, and reduce occurrence of an impact and a noise.

  • Patent number: 7047768
    Abstract: A knitting method of a tubular knit fabric uses a flat-knitting machine comprising at least one pair of facing needle beds that extend in the sideways direction and face each other front to back. At least one of the facing needle beds is capable of racking in the sideways direction, and the flat-knitting machine is capable of transferring stitches between facing needle beds. The tubular portion with directionality toward (oriented with respect to) another tubular portion is turned by a predetermined amount by transferring of stitches of the tubular portion with directionality and by racking of the needle bed. Knitting is performed so as to link the tubular portion with directionality to the other tubular portion in a state wherein the state of being turned is sustained.

  • Patent number: 6883352
    Abstract: An object of the invention is to improve yarn feeding conditions to a knitting needle and improve a loop pressing function and a yarn holding function for end stitches in a flat knitting machine provided with a compound needle. In a top portion 12 of a loop presser 11 advancing to a tooth mouth 10, a knitting yarn holding portion for end stitches 13 and a loop presser portion 14 are formed. The knitting yarn holding portion for end stitches 13 hides a tongue 25a from the yarn 22 at a wall portion 15 above the knitting yarn holding portion for end stitches 13 so that the problem of yarn entanglement that the yarn 22 fed to a hook 24a of the compound needle 23 from a yarn feeding port 20 is surmounted on the tongue 25a may be solved. A pressing portion 16 below the knitting yarn holding portion for end stitches 13 presses the yarn 22. The knitting yarn holding portion for end stitches 13 holds the yarn 22 outside the end stitch by winding it around it.
