  • Patent number: 10851493
    Abstract: A wire rope formed from a resin core and six strands, the resin core having an inner core with a circular cross section and an outer layer built up on the periphery thereof. The outer layer has a melting temperature lower than that of the inner core. The six strands are twisted together helically on the periphery of the resin core in an intertwining die in such a state that gaps are assured between the strands. The resulting wire rope is heated in a heating unit at a temperature higher than the melting temperature of the outer layer but lower than the melting temperature of the inner core. The wire rope is formed by subsequently compressing the six strands from the periphery thereof in a compressing die. The molten outer layer is hardened by natural cooling, after which the wire rope is taken up.

  • Publication number: 20150000242
    Abstract: With a wire rope comprising at least one plastic core (11) and a number of wire strands (15) twisted around the latter a helical groove (20) is respectively produced by machining around the periphery of the plastic core (11) for each wire strand (15). The cross section of these helical grooves (20) is respectively matched to the outside diameter of the wire strands (15). The plastic core (11) is provided with the helical grooves (20) for receiving the wire strands (15) by this machining directly before the wire strands (15) are wound onto said core. By thus forming the wire rope by means of this machining in order to produce helical grooves of the plastic core, optimal guiding of the wire strands in the twisted state is achieved, and so overall there are improvements to the properties of the wire rope.

  • Publication number: 20140248461
    Abstract: A process is described wherein pile yarn is woven with cotton weft and warp yarns to produce terry fabrics, such as towels. The fabric is then washed in warm water to dissolve the PVA fiber. The amount of fibers dissolved, depends upon the count of the yarn or yarns used. By dissolving the PVA fibers, a hollow air space is produced throughout the pile yarn, corresponding to an increase in the air space in the pile yarn. By increasing the in space in the pile yarn, the resulting towels are softer and bulkier than standard cotton towels. The present invention further relates to pile yarn in terry woven fabric (warp yarn), or weft yarn, in the case of flat fabrics.

    Abstract: An automatic lacer wraps bundles of polymeric fibers with thread, before the bundles are woven into a fabric mat and placed in a housing to form a gas-separation membrane module. A fiber bundle passes through a spool which is previously wound with thread on its outer surface. The thread is attached to the fiber bundle, so that when the bundle is moved through the spool, the thread is pulled from the spool, and automatically becomes wound around the bundle. Threads from two or more spools may be wrapped around the fiber bundle simultaneously. Lacing of the fiber bundles reduces the amount of tangling in the loom feeder, and improves the quality of modules made from the fiber bundles.

  • Patent number: 7000295
    Abstract: A method for forming a metallic fabric includes forming a composite yarn having a metallic wire core, and a cover yarn including a fluid-soluble strand such as co-nylon or polylactic acid. The composite yarn can be knitted into an intermediate fabric product. The soluble element is dissolved to leave a use fabric suitable for other processing, such as coating with materials such as latex. The non-fluid-soluble strand may be either a single strand or multi-filaments of steel wire.

  • Patent number: 6945026
    Abstract: An unspun yarn including a longitudinal main rope body formed from a least one fibre assembly of substantially untwisted and parallel fibres, and a least one reinforcing thread helically wound around the rope body and extending therealong in a single longitudinal direction. The direction in which the reinforcing thread is wound around the rope is reversed at predetermined intervals. A method of forming an unspun yarn, including providing a fibre assembly of substantially untwisted and parallel fibres and reinforcing thread, forming a longitudinal main rope body; intermittently imparting opposing twists to alternate sections of the rope body while drawing the reinforcing thread longitudinally into surface contact with a twisted section of the rope body, allowing the twisted section to engage the adjacent section of the reinforcing thread, releasing the opposing twists of the rope body causing the engaged reinforcing thread to wrap the rope body.

  • Patent number: 6840031
    Abstract: In an apparatus for cable manufacture, a cage strander rotates about a line axis at a chosen rotational speed. Bobbins supported by the strander dispense round conductors downstream of the cage strander. A forming apparatus downstream of the strander receives the conductors and forms them into many complementary segmented preshaped wires each having the desired cross-sectional profile in a final compact conductor. The conductors are positioned in a way that substantially corresponds to the orientations among wires in the final conductor. A first drive rotates the forming apparatus about the line axis substantially at the rotational speed of the strander. A second drive drives the forming apparatus. The drives are synchronized so that the conductors close about the core and cause the sides of adjacent wires to abut against each other to produce both the desired lay and a cable substantially without interstices between the wires forming the twisted conductor.

  • Patent number: 6789380
    Abstract: A bundle of conduit ducts is supplied by reels to a tandem arrangement of a pattern unit, a supply roller unit, an applicator unit and a delivery roller unit all supported by a wheeled base. The pattern unit has rows of discrete apertures for delivering conduit ducts at spatial positions. The supply roller unit and delivery roller unit each have spaced apart rollers supported by carriers in a frame to define a predetermined geometric passageway. The supply roller unit organizes the conduit ducts and the delivery roller unit supports a wrapped conduit ducts passed from the applicator unit. The applicator unit has a frame to support a rotator driven by a motor for rotation about a central axis extending perpendicular to the plane of rotation by the rotator. The rotator supports two reels one containing adhesive tape and the other metal wire on arbors at diametrically opposed locations.

  • Patent number: 6615571
    Abstract: An apparatus for assembling an optical cable comprises a spacer paying-out portion 7, a stationary ribbon supply unit 9, a gathering portion 14 and a taking-up portion 21. The spacer paying-out portion 7 supplies a spacer 2 having a spiral groove in the surface of a long spacer body from a supply reel 1 while revolving around a line axis X-X. The stationary ribbon supply unit 9 supplies a plurality of optical fiber ribbons 11. The gathering portion 14 forms the optical fiber ribbons 11 sent out of the stationary ribbon supply unit 9 into a cable core 15 by holding the optical fiber ribbons 11 within the spiral groove of the spacer 2 sent out of the spacer paying-out portion 7 and running forward while rotating on its center axis. The taking-up portion 21 winds the cable core 15 on a taking-up reel 20 while revolving around the line axis.
