  • Patent number: 5425251
    Abstract: A fabric take-off roller arrangement for flat bed knitting machines is provided with a driven fabric take-off roller that has roller elements disposed next to each other in the axial direction. To ensure that, even with irregular thickenings of the fabric to be taken off, engagement of the fabric take-off roller arrangement is provided both in the region of the thickening and in the adjacent region(s) of the fabric to be taken off, it is provided that the roller elements engage one another in a co-rotational manner at their ends facing one another and are rotatably held on respectively one support carrier, that the support carriers are pivotably held in a direction perpendicular to the orientation of the roller elements that the ends of the roller elements facing each other are flexibly seated against each other as well as in the support carrier, and that the fabric take-off roller is pressed against a counter-roller, between which rollers the fabric run is taken off.

  • Patent number: 5388430
    Abstract: A method of producing a fashioned, one-piece flat knitted article for a garment includes knitting several knitted article parts having a front part, a rear part and two sleeves separately and sequentially so that in each knitted article part always several loop rows are knitted in accordance with a pattern for said each knitted article part before transferring to a next knitted article part, knitting the front part and a shoulder region of any shape and pattern after finishing the sleeves with the formation of an arbitrarily shaped neck opening between the front part and the rear part, transferring connecting rows of the sleeves in a loop-like manner inwardly in a direction of the shoulder region and the front and rear parts until sleeve connecting edges are completely turned inwardly relative to the front part and rear part, and subsequently finally knitting a last knitted article part in correspondence with a pattern for said last knitted article part.

  • Patent number: 5379612
    Abstract: A method of knitting a multi-dimensional fabric for use in upholstery is accomplished by simultaneously knitting rib and jersey wales. The resultant fabric creates a layered or convex pocket appearance similar to that of pleated fabric formed by sewing. The method uses movement of the rib forming carriage to form pockets that are connected by the jersey stitches on the rear face and rib stitches on the face of the fabric.

  • Patent number: 5284030
    Abstract: In a flat knitting machine equipped with a manually movable handlebar (11) which is oriented parallel to a needle bed, the eccentrically mounted handlebar (11) is connected to a pivoting lever (15) which is the carrier of an armature (19) for a stationarily arranged electromagnet which can be excited via a control device and which, in the excited state, keeps the handlebar in an end position. The arrangement is such that, when the handlebar (11) is struck from above, the magnetic coupling can be released and it is also thereby possible to switch off the machine drive by hand in the quickest way possible.

  • Patent number: 5241841
    Abstract: In a knitting take-off device provided with gripping elements (14) movable through the comb gap of a flat bed knitting machine, the plane of the gripping elements (14) is directed perpendicular to the hooking planes of the knitting needles (13) mounted in the needle beds. As a result, the dimensions of the gripping elements are no longer limited by the width of the comb gap, and the gripping elements (14) can be coupled to additional elements, such as a cover stop rod (16). By means of the cover stop rod (16), the opening (14.2) of the gripping element (14) can be closed and a thread take-up space (20), closable by the head (14.1) of the gripping element (14), can be formed.

  • Patent number: 5214941
    Abstract: In the process for producing a fully fashioned flat fabric for a garment equipped with sleeves, first one of two body part, for example front parts (10), and additionally the two sleeves (11, 12) are knitted with separate yarn guides (A, B, C) to the completion of the sleeves. Subsequently, further knitting is carried out only with the yarn guide (A) for the front part (10), the end edges (11a, 12a) of the sleeves (11, 12) being tied stitch by stitch, by transfer, to the further formed body parts of the fabric. Thus the two sleeves (11, 12) are brought out of their original position parallel to the front part (10) into a desired transverse position in the finished flat fabric.
