  • Patent number: 3973742
    Abstract: Self-centering holder for hollow textile coils of varied lengths and diameters includes at least two rod-shaped substantially parallel-extending centering and clamping members, and means includes support and adjusting members for the centering and clamping members, the at least two centering and clamping members being mounted on the support and adjusting members and being respectively pivotable into a position wherein a hollow textile coil of given diameter is receivable over the centering and clamping members collectively and wherein the latter are in pressing engagement with the inner surface of the hollow textile coil, the support and adjusting members being located outside the hollow textile coil when the latter is received on the centering and clamping members.

  • Patent number: 3952550
    Abstract: A knit fabric is provided in which warp knit stitch chains are formed at spaces between inlaid warp ends and have loops thereof sinuously interlaced with filling ends laid at opposite sides of the warp ends so that the filling ends are held against the warp ends and both warp and filling ends are caused to interact in a manner producing an appearance approaching that of a woven structure. The method of forming this fabric and means for doing so are also disclosed.

  • Patent number: 3949570
    Abstract: A knit fabric is provided in which a woven structure is simulated by feeding spaced warp ends while laying filling ends at opposite sides of the warp ends and causing weft stitch courses to be knit so that needle loops thereof form wales running in the space between the warp ends and passing outside of filling ends at both sides of the warp ends while intervening sinker loop portions pass to one side of the warp ends. Such fabric can be formed on any type of weft knitting means that has been adapted properly.

  • Patent number: 3943731
    Abstract: A knit fabric is made to simulate a woven structure by arranging fancy warp stitch chains at spacings between inlaid warp ends so that filling ends laid at one side of the warp ends are knit-in while filling ends laid at the other side remain simply laid-in and are held in place by interaction of the warp ends and warp stitch chains thereat.

  • Patent number: 3941320
    Abstract: In a coil support frame of a winding machine having a pair of centering discs mounted in a position opposing one another and mutually spaced-apart so as to clamp a coil core therebetween, there is included a braking device operatively connected to at least one of the centering discs and actuable to brake rotation of the one centering disc and to apply pressure to the one centering disc in direction toward the other centering disc so as to reinforce the clamping force exerted by the pair of opposing centering discs on a coil core clamped therebetween.
