Patent number: 6658898Abstract: 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.Type: GrantFiled: May 29, 2002Date of Patent: December 9, 2003Assignee: Shima Seiki Mfg., Ltd.Inventor: Kazuyoshi Okamoto

Patent number: 6647749Abstract: A yarn carrier comprises a carrier base, a reciprocator, a feeder, and a movement converter. The reciprocator is supported on the carrier base to move in reciprocation with a traveling direction of the carrier base. An engaging surface is temporarily engageable with an accompanying member of a carrier accompanying device. The feeder, has a main-yarn feeding hole and a plating-yarn feeding hole, and supports at least one of the yarn feeding holes to freely rotate about an axis in a longitudinal direction of the feeder. The movement converter converts reciprocating movement of the reciprocator into rotation movement of the yarn feeding holes provided in the feeder, such that when the reciprocator is moved with its engaging surface engaged with the accompanying member, the yarn feeding holes can be rotationally displaced to change a positional relationship between the main-yarn feeding hole and the plating-yarn feeding hole.Type: GrantFiled: August 27, 2002Date of Patent: November 18, 2003Assignee: Shima Seiki Mfg., Ltd.Inventor: Kenji Ikoma

Patent number: 6598430Abstract: A compound needle (1) is provided with a slider (8) having two slider springs (11, 12). These are arched away from each other in a section immediately adjoining their insertion funnel (28). The compound needle has a slider slit (4), which initially is relatively narrow at its inlet (15), so that a guide section (4a) has been established there. Thereafter the slider slit (4) widens, so that a running section (4b) is established. The lateral bulge of the slider springs (11, 12) is of such a dimension that the slider (8) runs free in the running section (4b), and is guided without lateral play in the guide section (4a). The compound needle (1) also operates precisely in case of tension forces acting laterally on the slider (8) and requires only a small opening width of its funnel (28).Type: GrantFiled: June 21, 2002Date of Patent: July 29, 2003Assignees: Groz-Beckert KG, Shima Seiki Mfg., Ltd.Inventors: Klaus Ruoff, Norbert Gomeringer, Andreas Dietz

Patent number: 6578389Abstract: 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.Type: GrantFiled: February 14, 2002Date of Patent: June 17, 2003Assignee: Shima Seiki Mfg., Ltd.Inventors: Kazuyoshi Okamoto, Hideyuki Okawa

Patent number: 6571584Abstract: When binding off loops are formed in the process of a binding off process, intermediate wale loops, which are formed with the needles located between downstream wale loops and upstream wale loops of the binding off loops, are formed with the number of courses twice as much as wale loops between the downstream wale loops and those between the upstream wale loops. This can provide the result that when a force acts on the knitted fabric, the yarn is drawn out from the intermediate wale loops to enlarge the downstream wale loops and the upstream wale loops. This can allow the bound off part of the knitted fabric to have an excellent stretchability.Type: GrantFiled: January 11, 2002Date of Patent: June 3, 2003Assignee: Shima Seiki Mfg., Ltd.Inventor: Yasutaka Okayama

Patent number: 6568222Abstract: A sinker device comprises a sinker jack 50 which can be freely advanced and retracted with respect to a needle bed gap 4 and a sinker 30 supported on an upper surface of the sinker jack formed as a supporting surface in a freely swingable manner. The sinker 30 and the sinker jack 50 have sliding contact surfaces sidably contactable with each other which are each formed at a front side thereof with respect to a swinging pivot point. When the sinker jack 50 is advanced toward the needle bed gap 4 to move relative to the sinker 30, the sinker 30 takes the swinging attitude controlled by the sliding contact relation between the respective sliding contact surfaces of the sinker and the sinker jack, so that the sinker 30 is controllably swung to at least a knitted loop pushing level, a knitted loop releasing level and a stitch forming level.Type: GrantFiled: April 24, 2002Date of Patent: May 27, 2003Assignee: Shima Seiki Mfg., Ltd.Inventor: Toshiaki Morita

Patent number: 6550284Abstract: 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.Type: GrantFiled: June 5, 2002Date of Patent: April 22, 2003Assignee: Shima Seiki Mfg. Ltd.Inventor: Kazuyoshi Okamoto

Patent number: 6546761Abstract: A compound needle (1) is provided with a slider (8) having two slider springs (11, 12), whose ends constitute an open funnel pointing toward the hook (3). The ends, or legs (21, 22), constituting the funnel, are flattened. Therefore, starting at a starting point, the thickness of the material is reduced in the tapered area (29) toward the ends of the slider springs (11, 12). By means of this a correct functioning of the compound needle is also provided if the slider (8) is not completely centered. Moreover, it is possible to improve the easy movement of the slider (8) in the slider slit in that the funnel, formed by the legs (21, 22), can be embodied to be narrower at a constant width, than without the taper of the slider springs (11, 12).Type: GrantFiled: June 21, 2002Date of Patent: April 15, 2003Assignees: Groz-Beckert KG, Shima Seiki Mfg., Ltd.Inventors: Klaus Ruoff, Jürgen Schneider, Andreas Dietz
