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:
The invention relates to a method for producing a metal cord having three concentric layers (C1, C2, C3), of the type that is rubberized in situ, i.e. during the production thereof. The cord comprises a first inner layer or core (C1), around which N strands of diameter d 2 are wound together in the form of a helix with a pitch p 2 to form an intermediate layer (C2), N varying between 3 and 12. In addition, P strands of diameter d 3 are wound together around this second layer in the form of a helix with a pitch p 3 to form a third outer layer (C3), P varying between 8 and 20. The method includes the following steps: a first step in which the core (C1) is coated with a rubber composition known as "filling rubber" in the non-crosslinked state; a step in which the N strands of the second layer (C2) are assembled and twisted around the thus coated core (C1), so as to form an intermediate cord, known as the "core strand" (C1+C2), at a point known as the "assembly point"; a step in which the P strands of the third layer (C3) are assembled and twisted around the core strand (C1+C2); and a final twist value balancing step. The invention also relates to the device used to implement one such method.
Abstract:
Drahtseil (1), insbesondere Seilbahn-Tragseil, mit einem Kern, der von zumindest einer äußeren Lage (8, 10-13) von Seilelementen (9) umgeben ist, und der zumindest einen zur Datenübertragung vorgesehenen Lichtwellenleiter (3) aufweist, der in einem Metallröhrchen (5) eingebettete Glasfasern (6) enthält und der mit zumindest einem Draht (4, 4') zu einem Spiralseil (2) verseilt ist; dabei ist das Kern-Spiralseil (2) von einem Kunststoffmantel (7) umgeben, der eine Schutzhülle gegenüber der zumindest einen äußeren Seilelemente-Lage (8, 10-13) bildet.
Abstract:
The invention concerns a metal cord for use in a tyre carcass reinforcement, such as a heavy vehicle tyre, a composite fabric for use as layer of such a carcass reinforcement, a carcass reinforcement comprising said fabric and a tyre incorporating said carcass reinforcement. The inventive metal cord comprises a textile band, and is characterized that the band consists of a polyester or thermotropic aromatic polyester-amide. The inventive composite fabric is characterized in that it comprises a rubber composition which is reinforced by said cords. The inventive tyre is characterized in that its carcass reinforcement comprises said composite fabric.
