  • Publication number: 20030110606
    Abstract: When winding individual warp strip sections, the ends of the warp strips are fixed onto the surface of the same section at least at two adjacent warp strip sections. At each second warp strip section, a base element is attached to the warp strip, onto which the ends of the warp strip, by means of connecting elements mounted thereon, can be adhered. The time required for attaching the base elements is thus reduced.

  • Patent number: 6401314
    Abstract: For inserting a dividing cord loop into the opened shed warp on a sectional warping machine, a dividing device has at its disposal an introduction element (28) with a first, preferably movable guide arm (26) and a second, preferably stationary guide arm (27). The free ends (29, 31) of the two guide arms may preferably be led together in a pincer-like movement. The guide arms are preferably designed as tubes which in the led-together condition form a flow channel. With the help of an air conveyor (35), from a bobbin chamber (28) a dividing cord may be drawn off and as a loop be layed around a divided shed warp lying between the two guide arms and by way of a knotting means be connected to a cord loop. The connected cord loop is thereafter by way of a suction device or a blower device positioned and tensioned in a manner such that the cord loop bears at least on one side on the divided shed warp or on the warp web.
