Abstract:
Metallic load-carrying elements (3,23) are helically spun around a central member (1,21) comprising a supporting member or members (9,24) constituting a structure (4,24) which defines at least one passage (6,26) wholly accommodating at least one electrical or optical transmission element (7,27). The transmission element is thereby protected against stresses applied to the load-carrying elements. The central structure is radially and longitudinally self-supporting. The central member (1,21) is formed by causing the supporting member or members (9,24) and the transmission element or elements (7,27) to converge to a point from which the central member (1,21) is withdrawn continuously. The load-carrying elements (3,23) are subsequently applied to the central member (1,21). Cables of practically unlimited length can be produced.
Abstract:
In a built-up core for the bead of a pneumatic tire, the wires (A,B,C) of each lay (8) of the built-up core (4) are of a trapezoidal cross section. Between the wires (A,B,C) of each lay (8) of wire and the wires (A,B,C) of the next, overlying lay (8) of wire, there are wedge-shaped clearances (9). As a result, the wires (A,B,C) of each lay (8) of wire find a support on the edges of the wire of the underlying lay of wires so that they cannot be displaced against each other during the production of the tire.
Abstract:
An operating wire has a multi-twisted structure constituted by twisting side strands, each formed by twisting element wires together around a core strand. A side element wire of the side strand faces the outside of the operating wire in the radial direction at a site located on the outer circumference of the operating wire and has a flattened surface where a flat portion provided in a portion of the side element wire in the circumferential direction extends in the X axis direction, the length in the X axis direction of the flattened surface being 4.8-11.0 times the diameter of the side element wire, and the pitch magnification of the side strand being 7.0-12.0 times the diameter.
Abstract:
A steel cord for tire reinforcement according to the present invention is elongated in one direction and comprises a plurality of strands twisted periodically on one another, and the steel cord for tire reinforcement is characterized in that the steel cord is formed to have a first waveform having a first waveform surface and a second waveform having a second waveform surface, the first and second waveforms are formed to overlap each other, and a predetermined inclined angle is defined between the normal of the first waveform surface of the first waveform and the normal of the second waveform surface of the second waveform.
Abstract:
A metal cord has cylindrical layers formed of an internal layer, an intermediate layer, and an external layer. The in internal layer includes M threads. The intermediate layer includes N threads wound in a helix around the internal layer. The external layer includes P threads wound in a helix around the intermediate layer. An inter-thread distance, D2, between the threads of the intermediate layer is greater than or equal to 25 μm. An inter-thread distance, D3, between the threads of the external layer is greater than or equal to 25 μm.
Abstract:
A hybrid rope constructed of a plurality of strands, wherein each strand is constructed of a fiber center, a jacket surrounding the fiber center, and a plurality of wires surrounding the jacket. The fiber center can be constructed of one or more high-strength synthetic fibers or yarns. The jacket can be constructed of polypropylene, thermoplastic polyurethane, high-density polyethylene, linear low-density polyethylene, nylon or other similar materials. The jacket can have a braided or woven design and adds a protective layer between the fiber center and the wires. The wires can be constructed of high-strength steel wires, galvanized steel or stainless steel. The fibers or yarns that make of the fiber center are twisted to lay right and then covered with the jacket. The wires then surround the jacket and are twisted to lay to the left. This creates a torque-balanced condition of the hybrid rope.
Abstract:
A bicycle control cable is provided with a central wire and a radial protrusion. The central wire includes at least one metallic strand defining a radially outermost surface of the central wire. The radial protrusion extends along the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire. The radial protrusion reduces a sliding resistance of the central wire. The central wire and the radial protrusion are configured and arranged to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.
