  • Patent number: 4548057
    Abstract: This invention relates to a single- or double-Jersey knitted fabric which not only has a closed starting seam, but also a closed terminal seam (24, 24', 24") which can follow a line of any shape, and a method of making the same on a machine having stitch-forming elements and having an arrangement for transferring and racking the formed stitches. The closed terminal seam (24) of the fabric may for example be formed by transferring the last terminal seam stitch (16), then racking the same, and finally transferring it to the next seam stitch and then knitting the two transferred stitches with a thread (25, 22) which may be either a separate thread or one used to form the remainder of the fabric. The linking stitch so formed (31) is then racked again and the next-succeeding selvedge stitch transferred thereto before being knitted with the thread into a further linking stitch.

  • Patent number: 4516412
    Abstract: The invention is concerned with a knitting cambox system for a flat knitting machine with front and rear needle beds arranged gable-fashion and adapted for the production of multicolor knitted fabric a single pass of the machine carriage.An improvement is achieved in this invention by the interassociation of a plurality of independently-operable needle sinkers at the two sides of the knitting cambox so as to provide a timewise-staggered drawing-down of the stitches and increased stitch production.

  • Patent number: 4505134
    Abstract: A flat knitting machine, particularly one electronically operated and controlled and having two needle beds (17, 18), is provided with knitting assemblies (19-22) having cam parts for needle control, while the needle beds (17, 18) are mounted on the machine frame for reciprocating movement past the knitting assemblies. These can be coupled to a flat knitting machine which is provided with needle bed driving means, further flat knitting machines without an intrinsic drive, the needle beds of the latter being rigidly connected with the driven needle beds (17, 18) of the driven flat knitting machine (A). The flat knitting machine may be provided with a mechanism for adjusting the width of the comb gap and for each knitting assembly (19-21) with a special takedown mechanism (78-81) and with a thread change device (97-108).

  • Patent number: 4490994
    Abstract: In a flat knitting machine having a needle selector device and selector jacks (50), which can be acted on by press cam parts, and needles (42) with a butt (47) which can be disconnected from the cam parts, there are arranged, in the direction of movement of the machine at each side of each needle selection locality (21) of the needle selector device, a cam part (23, 24). Both cam parts (23, 24) serve to move selected selector jacks (50) longitudinally and to effect a longitudinal movement into different positions (O, I, II) of the selector jacks. Furthermore, each knitting system is provided, for both directions of movement, each with a pair of adjustable draw-off cam parts (15, 17) of different draw-off length, the one of which parts acts on a fixed butt (44) of the needles (42) and the other on the butt (47) which can be disconnected by means of the selector jack (50).
