  • Patent number: 6672113
    Abstract: In order to seamlessly knit knitwear, such as a sweater, having a widened neckline 10a of a front body 2a and a front drop formed in the neckline 10a in a relatively simple method, stitches at a right side of the front neckline 10a and stitches at a left side of the front neckline 10a, retained on the first needle bed FB, are shifted from inside to outside, with gradually increasing distances, so that the stitches can be retained on the first needle bed FB, with empty needles inserted in the spaces between those stitches; at least one of the shifted stitches 31, 32 at and outer side end portion of the right side of the front neckline 10a and at least one of the shifted stitches at an outer side end portion of the left side of the front neckline 10a are fed to the second needle bed BB so as to be situated next to the stitch at each side end of the back neckline 10b retained on the second needle bed BB, whereby the neckline 10 is increased in diameter, followed by formation of widening stitches on the empty nee

  • Patent number: 6308536
    Abstract: The present invention relates to a method of producing three-dimensional knits. In accordance with the invention narrowing the loops is done by loops covering a partial area of the needle bed being transferred to needles arranged nearer to the middle of the knit and subsequently knitting further continued, and widening the loops is done by loops covering a partial area of the needle bed being transferred to needles arranged remote from the middle of the knit and subsequently knitting further continued. As an alternative to this, needles may be rendered inactive in a partial area of the needle bed over at least one course and subsequently reactivated.

  • Patent number: 6176105
    Abstract: For preventing holes from occurrence at an internally widened area of a rib knitted fabric, at the area, two needles, one on the front needle bed, the other on the back needle bed, are made empty. Then, a stitch held by an adjacent needle to one of the two empty needles is transferred to the other of the two empty needles so that two continuous needles on one needle bed are made empty and that the former empty needle on the other needle bed is provided with the transferred stitch. A yarn feeder is made to move over the area while feeding yarn till one needle before the two empty needles, then back above the area while feeding the two empty needles and an intermediate opposing bed needle, and move over the area while feeding yarn from the subsequent needles after the two former empty needles.

  • Patent number: 6122937
    Abstract: The present invention relates to a method of producing a three-dimensional knit, i.e. a knit whose area is shaped spatially. In accordance with the invention a homogeneously tough three-dimensional knit structure is achieved when loops in specific portions are widened and/or narrowed, this widening/narrowing of the loops being done at many locations arranged distributed homogeneously over the area to be formed three-dimensionally. In the same way a three-dimensional knit may be produced in which the knitting needles are inactivated at least in part over at least one course in the portion to be shaped and later reactivated whilst in the other portions full knitting is continued.

  • Patent number: 6079232
    Abstract: A widened loop is formed by using a flat knitting machine which has at least a pair of needle beds and one of the needle beds can be moved sideways. A widening needle is made to be empty, and yarn is fed from one end of the knitting range to a needle short of the widening needle. Next, yarn is not fed to the widening needle but to a needle next to the widening needle. The yarn feeder is reversed and yarn is fed to the widening needle. Then the yarn feeder is reversed again and yarn is fed to a needle next to the needle to which yarn has been fed. According to the method loops 21, 23 on both sides of the widened loop 11 are connected together by a cross-over yarn 25, and the widened loop 11 is held by a loop 13 of the previous course. Therefore it will not be pulled up. Because of these arrangements, an open gap will be hardly generated around the widened loop 11.

  • Patent number: 5701766
    Abstract: A tubular knitted fabric is broadened while fully preventing generation of open gap. Yarn is hooked on a needle of a second needle bed and twisted to form a loop, and this loop is transferred onto a first needle bed to become a broadening loop. A subsequent stitch is formed on the broadening loop and transferred back to the second needle bed. Yarn is hooked again on a needle of the second needle bed and twisted to form a loop, and this loop is transferred to the first needle bed to become a broadening loop.

    Abstract: A fabric manipulating device for use with a knitting machine of the type having a flat needle bed containing a plurality of equi-spaced knitting needles tricked into the bed includes a carrier that is mounted on the bed for sliding, needle-by-needle movement along the bed to effect loop manipulation. A cam-controlled linking needle is mounted on the carrier in the plane of the knitting needle in opposing relationship thereto for movement to and from the knitting needles to effect the intended knitted loop linking manipulation. A cam-controlled positioning member and loop restricting member, operating in timed relationship with a cam-controlled loop expanding mechanism and stationary loop contacting surfaces, orients and expands a knitted loop retained on the stem of a knitting needle opposing the linking needle to permit the linking needle to enter the expanded loop while a cam-controlled actuator causes the knitting needle to knock-over the loop onto the linking needle.
