Patent number: 6857294Abstract: An object of the invention is to obtain an intarsia pattern fabric which is not likely to cause yarn entanglement, eliminates the need for divided knitting, and provides good productivity even when a cylindrical knitting fabric is to be knitted. in a double bed flat knitting machine, a carriage and an intarsia carrier capable of knitting with two sets of cams are used to knit two courses of knitting fabric by moving a carriage six courses. An intarsia pattern is knitted at a front needle bed FB, and a knitting yarn between the intarsia carrier halted near a boundary and a knitting needle F is used to perform kick-back of the intarsia carrier by the third-course movement of the carriage. A back body is knitted while the yarn is hooked on an unused knitting needle F in a back needle bed BB. The sixth-course movement of the carriage releases a knitting yarn from the knitting beed F in the back needle bed BB while the back body is being knitted.Type: GrantFiled: May 23, 2002Date of Patent: February 22, 2005Assignee: Shima Seiki Manufacturing LimitedInventor: Kazuyoshi Okamoto

Patent number: 6796149Abstract: 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.Type: GrantFiled: August 14, 2003Date of Patent: September 28, 2004Assignee: Shima Seiki Mfg., Ltd.Inventors: Kazuyoshi Okamoto, Yukihide Maeda

Patent number: 6761048Abstract: A loop of a row of binding-off loops is formed with finer yarn than yarn used in a rib knitted fabric part. Also, a binding-off loop of the row of binding-off loops formed following a final loop of an odd wale of a knitted fabric at an end thereof and the binding-off loop of the row of binding-off loops formed following a final loop of an even wale of the knitted fabric are overlapped with the adjacent final loops on the underside thereof and also the binding-off loop formed following the final loop of the odd wale and the binding-off loop formed following the final loop of the even wale are intersected with each other. This can prevent the binding-off loops different in orientation from coming out in the bound off part, thus enabling the bound off part to be formed in a similar appearance to the set-up part.Type: GrantFiled: September 26, 2003Date of Patent: July 13, 2004Assignee: Shima Seiki Mfg., Ltd.Inventor: Kazuyoshi Okamoto

Patent number: 6748770Abstract: 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.Type: GrantFiled: July 24, 2003Date of Patent: June 15, 2004Assignee: Shima Seiki Mfg., Ltd.Inventor: Kazuyoshi Okamoto
