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.

Abstract: The invention refers to a method and a device for the manufacture of flexible tubular bodies in which one or more profiled strands are deformed spirally in a permanent manner before proceeding to winding it or them spirally in order to form a cylindrical carcass, by making the profiled strand pass over two pulleys in succession.The profiled strand is wound on the flat round each of the pulleys, the axes of the two pulleys being angularly offset so as to cause a permanent twist in the length of profiled strand situated between the said two pulleys.

Abstract: In the manufacture of bundles of at least ten twisted pairs or quads of electric wires, a compact design of the first twisting stage and a servicable guiding system for guiding the pairs from the first twisting stage to the twisting closer of the second twisting stage is obtained by having at least two groups of SZ-twisting devices in the first twisting stage, the rotating twisting heads of the two stages radially staggered and the guide pulleys of the respective inner twisting head which are arranged at the transition from the first to the second twisting stage provided with several guiding grooves for the twisting units so that they can guide twisted units from both the inner and outer twisting heads.

The wire braid includes a plurality of interwoven strands of wires, and each strand includes a plurality of wires having a uniform tension and a twist of from approximately one turn for each two and one-half to three inches. Further, each of the wires of the strand is preformed to produce a helical tension spring configuration, and the strands are braided under a relatively high tension. The hose is made by a method including the steps of preformng wires to produce the helical tension spring configuration, combining a plurality of such wires under a uniform tension and twisting such wires to form strands, and braiding a plurality of such strands under high tension.

Abstract: A metallic cable (10) suitable for reinforcing elastomeric articles comprises two or more substantially identical, helically disposed filaments (11, 12, 13) nested together and twisted together, such that the cable has a lay length (L) that is at least two times greater than the pitch length (P) of the filaments. The cable is manufactured by drawing metallic filaments from a bobbin means (31, 32, 33) and then guiding them through a means for deforming (34) that shapes the filaments into helixes. The filaments are positioned beside and against each other such that each filament is in contact with at least one other filament. After a sunken rotating pulley (37) guides the filaments through the hollow bearing (23) of a first flyer (21), first and second rotating flyers (21, 22) twist the helically disposed filaments together to form a cable.

Abstract: In such a device, with a rotor support frame and a drafting wheel mounted transversely of its axis of rotation, the effects of the gyroscopic and centrifugal forces on the rotor support frame should be avoided so far as possible. For this, an oppositely-driven rotary member (13) is mounted on the axis of rotation (12) of the drafting wheel (10). The shape, dimensions, masses and/or velocities of rotation of the drafting wheel (10) and the rotary member (13), as well as the parts (26,25,14,27,28; 34,33,15,35,36) rotating with them, are selected so that the product of the mass moment of inertia and the angular velocity of the counter-rotating components is at least approximately uniform in magnitude. The drafting wheel (10) and the rotary member (13) are each mounted upon the common axis of rotation (12) by means of a hollow shaft (28,36).

Abstract: A metallic cable comprises a strand of identical helical shaped filaments positioned beside and against each other such that each filament of the strand is in line contact with at least one other filament of the strand. The helixes of the filaments of the strand are sloped in a first direction. A single filament is twisted with the strand in a direction opposite to said first direction. An apparatus and a method for manufacturing the metallic cable are also disclosed.

Abstract: To provide a predetermined pre-set twist or rotation about an angle corresponding at least approximately through the spiraling angle of strands (8) wrapped about a core wire or strand (48), the individual surrounding strands are passed through directionally orienting dies (20, 28) which may receive circular strands and impart an approximately truncated wedge-shape thereto, or directly receive pre-shaped strands. The orienting dies are angularly adjustable in a holder (26) which, in turn, is rotatable about an axis transverse to the axis of the die opening, all the dies being secured to a carrier plate which is axially adjustable with respect to the stranding die (7) of the apparatus.

Abstract: The deformation of corrugations in a corrugated conductive tape, utilized as a screened layer for screened cables or as an outer conductor for coaxial cables, due to pulling tension of the screened cable is prevented by an apparatus for manufacturing screened cables such that the corrugated conductive tape is transferred at the same rate as a cable core which is covered by the corrugated conductive tape by a forming device.

Abstract: An apparatus for cabling wires into a predetermined stranded configuration has at least one first pay-off bobbin rotatably supported inside a carrier, in its turn freely rotating inside a cage-type device and coaxial with it.The cage is supported to rotate about its own axis.Part of the wires constituting the produced cord can be drawn through the apparatus coming from a second, external to the apparatus, pay-off bobbin.The carrier comprises means for guiding the wires along a path developed from one extremity and/or from the first pay-off bobbins to the other extremity of said carrier, said path being not coincident with the axis of the apparatus, and means, disposed along said path, for permanently deforming the wires by bending.

Abstract: Wires are wound and simultaneously laid directly on the core of the product to form a wound layer between the adjacent wires of which there are peripheral spaces constituting from 15 to 70 percent of the wire diameter. The partly finished twisted wire product made in this manner is subjected to compression so as to cause its plastic deformation in order to obtain the desired shape and size. The wires of the wound layer of the finished product have a contact with the core substantially along the surface thereof as a result of compression applied to the product so as to cause its plastic deformation to produce the desired shape and size.A twisted product made by applying this method has uniform mechanical properties over its whole cross section.

Abstract: A method and apparatus for making a cord to be used for reinforcing an elastomeric article such as a tire for a motor vehicle are disclosed. The cord has a core formed by twisting together a group of wires and a series of radially disposed crown layers of wires wound helically about the core or next innermost crown layer side by side and parallel to each other. The apparatus has two machines each having a cage and a shuttle disposed in the cage for winding crown layers from bunches of wires. A device for flexing the wires used to form the crown layers to deform them before winding is included. The two machines are coupled together by a device which determines the relative speeds of rotation of the first and second cages at a 2:1 ratio, respectively.

Abstract: The disclosed method of making a shape-stranded rope includes twisting large wires into strands by twining them in at least one layer about a core with a sheathing of a soft deformable material, plastic drawing of the strands, forming the strands into a shaped profile and twisting the strands into the rope. The plastic drawing is effected until every round wire of the strand acquires a wedge-like profile, with the wires adjoining the sheathing becoming partly embedded in this sheathing, and the strand acquires a substantially smooth peripheral surface. The method enables, while using round wires, to increase the structural density of the strands, and also to enhance the flexibility, strength and wear resistance of the shape-stranded rope, the rope manufactured by the disclosed method being usable by various industries.

Abstract: A method is provided for making metal cords to be used as reinforcing elements in elastomeric structures which comprises arranging the wires in groups with the wires of each group being arranged coplanar and side by side, permanently deforming the wires by bending to wind the wires in a regular and uniform helical arrangement, with the helexes of all the wires having the same geometrical characteristics. The resulting cord is free from residual tensions which might loosen the mutual strand.

Abstract: A wire construction is provided in which five fine filaments of stainless steel wire are helically overwound about a center filament, also formed of stainless steel. The diameter of the central filament is slightly larger than the diameter of the helically wound filaments, which are of uniform diameter. The wire so constructed retains a high degree of elasticity following manufacture, and is especially suitable for application as an orthodontic wire for use in bracework for straightening teeth, especially the teeth of adolescent children. The wire is formed on a multi-bobbin tubular strander, and during manufacture all of the wire strands are maintained under tension, although the center strand is maintained under greater tension than the helically overwound filaments.
