Abstract:
A linear member for medical use having stretchability and flexibility while maintaining sufficient strength is developed. The linear member for medical use includes: an inner helical body including a plurality of helically wound wires, the inner helical body including a space portion inside, gap portions being provided in an axial direction between each wire; and an outer helical body provided outside of the inner helical body including a plurality of wires helically wound in such a manner to form a layer along an axis of the helical body and a helical direction of the outer helical body is opposite to that of the inner helical body with gap portions being provided between each of the wires, the outer helical body being disposed to provide a multilayer structure. Consequently, a linear member for medical use maintaining stretchability and flexibility while having strength that enables application of sufficient fastening force, which prevents a bone from being damaged, can be provided.
Abstract:
Hybrid rope (20) comprising a core element (22) containing high modulus fibers surrounded by at least one outer layer (24) containing wirelike metallic members (26). The core element (22) is coated (23) with a thermoplastic polyurethane or a copolyester elastomer, preferably the copolyester elastomer containing soft blocks in the range of 10 to 70 wt %. The coated material (23) on the inner core element (22) is inhibited to be pressed out in-between the wirelike members (26) of the hybrid rope (20) and the hybrid rope (20) has decreased elongation and diameter reduction after being in use.
Abstract:
A tire includes a carcass structure including at least one carcass ply, a belt structure applied in a radially outer position with respect to the carcass structure and a tread band applied in a radially outer position with respect to the belt structure. The belt structure includes at least one reinforcing strip incorporating a plurality of reinforcing elements arranged substantially in the circumferential direction. The reinforcing elements include at least one high-elongation metal cord. The metal cord includes a plurality of intertwined strands and each strand includes a plurality of filaments. Advantageously all the filaments of each strand have a diameter not greater than 0.175 mm.
Abstract:
The invention relates to a combined cable having a core cable made of high-strength plastic fibers present as a twisted monofilament bundle (1) or a plurality of twisted monofilament bundles (6), and having an external layer (2, 7) of steel wire strands (4, 5), characterized in that the monofilament bundle or bundles (1, 6) is or are stretched to reduce the diameter and held in a cladding (2, 7), particularly braided cladding, in this state. The strain of the core cable under load is thus reduced, so that the load distribution between the steel cross-section and the plastic cross-section of the cable is improved. In the same sense, in reverse, in order to have the strain behavior of the strand layer approach that of the core cable, the cable has an intermediate layer (3) made of an elastic plastic, in which the steel wire strands are pressed at a distance from each other, such that the external layer stretches under load and contracts radially.
Abstract:
A fine steel cord for the reinforcement of synchronous belts is presented. The fine cord has a distinct load elongation curve characterized by a very low structural elongation (below 0.09% preferably below 0.06%), and a high equivalent modulus between 0.2 and 20% of the breaking ', load. The favorable results are maintained when the cords are coated with an elastomer coating. Such a fine steel cord reduces the geometrical spread on the tooth pitch of the synchronous belts during use. A method to produce such a fine steel cord is also presented.
Abstract:
A cable (11) is provided comprising a steel cord (12) and a polymer material (15).The steel cord (12) has a diameter less than 2.5mm, and is coated with the polymer material (15). The cable (11) has a permanent elongation of less than 0.05 % at a permanent force of 50N, after being subjected to a force of 450N. Further, a window elevator system (300) comprising such a cable (11) is provided.
Abstract:
A cable (211) is provided comprising a steel cord (212) and a polymer material (215). The steel filaments (213) of the steel cord (212) are coated with an adhesive before the penetration of the polymer material (215). The cable (211) has a structural elongation less than 0.025% and an E module 4% greater than the E module of the steel cord (212). These two improvements further decrease the total elongation of the cable at certain load.
