Delivery Twist Type Patents (Class 57/59)
  • Patent number: 4519197
    Abstract: In the laying-up of the cores of a multiple core cable in which the cores travel from a plurality of auxiliary platforms rotatably mounted on a main, rotatable platform to a laying-up member, the platforms are rotatable by separate motor drives, one for each platform, and the cores operate position sensors intermediate the auxiliary platforms and the laying-up member so as to speed up or slow down the motor drives for the auxiliary platforms dependent upon the positions of the cores as they pass from the auxiliary platforms to the laying-up member thereby eliminating residual torsion in the cores of the cable.

  • Patent number: 4457129
    Abstract: An electromagnetic disc type tension control in which the yarn guiding post is slotted off-center between the discs so that the yarn being tensioned is received between the discs and exerts a torsional force on the tension discs to cause the tension discs to rotate in order to enhance the dissipation and self-cleaning of the yarn finish accummulated therebetween.

  • Patent number: 4454710
    Abstract: Method and apparatus to produce a continuous filament textured yarn with unusually low crimp contractions and intermittent crimp along its length. This is accomplished by the use of an electromagnetic tension device to control the draw in the yarn being supplied to a false twist device driven at a speed to provide low false twist in the yarn being twisted. The apparatus includes a control between the electromagnetic tension control and the yarn supply package to prevent the yarn coming off the package from rotating in a full balloon path and consequently prevent entanglement of the yarn in the yarn guides to a yarn consuming machine.

  • Patent number: 4407116
    Abstract: An apparatus for stranding wire, cables, ropes or the like, has one or more rotatable supports and a plurality of receptacles are non-rotatably mounted on each of the supports. A bundle of wound wire which is to be stranded is contained in each one of the receptacles which are positioned so that the axis of each bundle of wire is substantially parallel to the axis of rotation of the support. The wires from each of the bundles in a receptacle are then guided to a stranding point.

  • Patent number: 4320619
    Abstract: An improved wire or fiber strand payoff neutralizer adapted for multi-position application is described, which permits numerous individual strands of wire or fiber that will be formed into a cable to be payed out linearly and uniformly under controlled and regulated tension to the other components of a cabling machine. The present invention utilizes a split shaft, the reel containing the wire or fiber strand being mounted on an arbor portion of the split shaft, and a flyer being mounted on the driven portion of the rotor shaft. The wire or fiber strands then travel from the product supply reel to the flyer and then back to the hollow core of the rotor shaft and thence to the other components of the cabling system. The flyer and the rotor shaft rotate at the same speed as the other components of the cabling system, as well as in the same direction.

  • Patent number: 4317328
    Abstract: A continuous process of drawing a plurality of strands from a supply and neuturalizing the twist as taken from supply reels, twisting the various strands into a cable and then passing the cable over capstans and an accumulator to maintain proper tension in the cable and then on to a closer where the cable is packaged, all units being driven from a common shaft in time with each other and in a one-to-one relationship with the elimination of back twist in individual strands and the maintenance of uniform tension on the individual strands and a minimum tension on the cable.

  • Patent number: 4164840
    Abstract: Yarns or filaments from producers packages, having little or no twist therein and mounted upon two-for-one spindle units, are uptwisted, directed to a ply twisting unit where the twisted filaments are plied and downtwisted onto a takeup bobbin of a spindle unit. A selected percentage of the required twist is inserted as the plied, cabled filaments are wound upon the takeup bobbin and the remainder of the required twist inserted as the filaments are unwound from the takeup bobbin and directed to a winder unit. Alternatively, the rate of twist applied to the plied filaments may be increased by driving the traveler ring, thus increasing the life or the speed of the traveler which directs plied filaments to the driven takeup bobbin. Occasionally, when two-for-one spindle units are applying extremely high twist, which slows down the delivery of twisted plied filaments, the driven downtwist takeup spindle unit may employ a super high speed stationary traveler ring.

  • Patent number: 4157006
    Abstract: The invention concerns a device for up-twisting directly a spinning package having the shape of the cake. According to the invention, the device comprises a vertical spindle driven in rotation at constant or variable speed. Centering and positioning means are provided for the cake on the spindle, said means preferably comprising two cones placed in opposition and fitted at each extremity of the cake. The cones are characterized by the lower cone being secured to the spindle axle and the package being positioned between the two cones by means of a locking element which connects the lower cone to the upper cone. Preferably, the upper cone is associated with a cap flyer which projects beyond the outer edge of the package. The invention applies itself particularly well to up-twisting.

  • Patent number: 4129979
    Abstract: A yarn-twisting apparatus comprises a spindle receiving the supply spool or bobbin, a rotating can or sleeve surrounding the spool and the bobbin, a yarn takeup arrangement for drawing the yarn from the upper end of the can, and a housing surrounding the can. According to the invention, the stationary housing and the upper and lower ends of the spindle are provided with closures which reach close to the spindle at the bottom and form an opening traversed by the yarn at the top. Means is provided for enabling the upper closure to be removed or displaced for ready access to the interior of the housing. The system reduces the power consumption required for twisting the yarn.

  • Patent number: 4102117
    Abstract: A twisted pair of wires is produced by drawing two insulated wires from two supply reels while rotating one wire supply reel about the other. A capstan and tachometer measure the linear rate at which the twisted pair is being drawn. The output of the tachometer is controllably and variably divided and used to control a power inverter that drives a motor which rotates the one wire supply reel about the other. The variable ratio between the linear wire movement and the rotary or twisting movement is controlled by a random generator producing a series of numbers representing length per twist of the twisted pair, between fixed limits.
