  • Patent number: 4784341
    Abstract: A textile yarn winding apparatus for winding a continuously produced yarn, said apparatus being of the type having spindles carrying two axially aligned flanged bobbins and a yarn guide which is reciprocated along the length of one or other of the flanged bobbins so as to lay yarn wherein the yarn guide may be moved from its path along the length of one bobbin to a corresponding path along the length of a second bobbin when it is desired to transfer the winding from one bobbin to another, whereby the take-up of the yarn continues without interruption, the yarn being led from the surface of the completed bobbin over the adjacent flanges of the completed and empty bobbins to the barrel of the empty bobbin thus connecting the two.

  • Patent number: 4427037
    Abstract: The invention relates to shuttleless looms in which weft is carried through the warp shed by means of at least one weft carrier which is reciprocated into and out from the shed to cause the weft to be carried through the shed. In order to vary the speed of the weft carrier during its passage through the warp shed, a mechanism is provided including both a drive member connected to the weft carrier and a guide member, the drive member being connected to a reciprocating drive which also engages the guide member, the arrangement being such that during each loom cycle the guide member acts to cause the point of connection of the drive to the drive member to be altered so as to vary the speed of the drive transmitted to the weft carrier.
