    Abstract: A concentric strander has an elongate concentric shaft that defines a shaft axis and supports for rotatably supporting the concentric shaft. A number of wire bobbins are spaced at substantially equal intervals along the shaft to form spaces between the bobbins. Each bobbin has an axis substantially coextensive with the shaft axis for rotation about the shaft, and each bobbin has a maximum radial diameter. The strander has take-off sheaves, mounted on the shaft, that are associated with a wire bobbin and that take the wires from the bobbins and guide them to a point radially outwardly beyond the maximum predetermined radial bobbin diameter. The take-off sheaves subsequently guide the wires in a direction substantially parallel to the shaft axis and define, on rotation of the concentric shaft, a cylindrical envelope. At a downstream end of the shaft, the strander has a closing device that receives the wires from the bobbins and applies them on a core.

  • Patent number: 4709542
    Abstract: A method and apparatus for making a twisted cable of unlimited length. The apparatus which is operative for performing the method includes a rotating reel having a group of wires or filaments wound thereon, a flyer which rotates around the reel for unwinding the group of wires or filaments therefrom, and a gathering assembly rotating with the flyer for gathering the individual filaments or wires from the group and twisting them to form a cable. The apparatus further includes a take-up assembly for drawing the cable from the gathering assembly and winding it on a take-up reel, and a control assembly for controlling the rotational speed of the flyer relative to the rotational speed of the reel to achieve a substantially uniform length of twist in the cable throughout its extent.

  • Patent number: 4693069
    Abstract: A heat-insulating jacket extends around each rotating can of a doubling machine. Half way up the height of the can envelope surface, an extraction line for extracting the air heated by friction as the can rotates extends into the interior between the jacket and the can. The end-face boundaries of the rotating can and/or top and bottom closure members of the jacket are such that the pressures of the air drawn into the jacket are at least substantially equal at the top and at the bottom.

  • Patent number: 4607481
    Abstract: There is disclosed an improved feedstock package for a spiraling machine. The package comprises filamentary yarn having a twist of less than 5 tpi wound around a king spool. In contrast to prior art cone packages, the invention significantly reduces package distortion and threadline breakage in high speed spiraling operations employed in, for example, making reinforced plastic hose. Preferred embodiments include the yarn being greige yarn and the package rotational speeds on the spiraling machine being at least 1,400 rpm.

  • Patent number: 4599853
    Abstract: An apparatus and method are described for producing compact stranded conductors on single and double twist machines. This is achieved by preshaping and metering the preshaped wires to have generally sectored cross-sectional profiled complementary configurations and positioning and orienting the preshaped wires to substantially correspond to their positions and orientations in relation to the core wire in the final compact twisted conductor. The wires are metered to a double twist strander which is used to initially twist the preshaped wires about the core wire in a generally loose construction, and these wires are subsequently locked into abutment against each other when imparted a second twist to form the compact composite conductor.

  • Patent number: 4581885
    Abstract: Changing relative positions of conductor pairs along a telecommunications cable core by passing the unstranded pairs, as they approach the core unit forming means, through individual guides which are reciprocally moved across a feedpath for the pairs, the guides being disposed in series along the feedpath with each guide aligned for unobstructed passage of its conductor unit along the feedpath. In this construction, means to reciprocate each guide overlaps those of other guides, thereby reducing the total height of the apparatus.

  • Patent number: 4574574
    Abstract: A stranding machine including a plurality of reels on which filament to be stranded is wound; a separate, rpm-controllable motor connected with each reel; rpm control devices connected to each reel motor for controlling the reel rpm with respect to the stranding speed to determine the tension of the filament running from the reel; a separate compensating roller associated with each reel; and a separate support component carrying a respective compensating roller and being displaceable in opposite first and second directions. Each support component is coupled to the respective rpm control means for controlling the rpm of the respective reel drive motor as a function of displacement of the support component. The filament, as it runs about the compensating roller, exerts a force on the support component in the first direction. A force exerting assembly is connected with each support component for exerting a force on the support component in the second direction.
