Abstract:
A rope structure is made by compacting a bundle of synthetic filaments by passing the bundle through a compacting die, further compacting the bundle by subjecting it to a reduced atmospheric pressure and, while the bundle is compacted, extruding a plastic sheath around the bundle.
Abstract:
Die Erfindung betrifft ein Seil aus textilem Fasermaterial für Anwendungen, in denen Schrägzug auftreten kann, dadurch gekennzeichnet, dass das Seil ein Kern/Mantel-Seil ist, dessen Kern (1) und dessen Mantel im wesentlichen aus textilem Fasermaterial bestehen, dessen Kern (1) verseilt ist und welches zwischen Kern (1) und Mantel eine kraftschlüssige Umwindung mit einem Zugelement (2, 2', 2'') aufweist.
Abstract:
A security device has a flexible strap (26) with a lock unit (28) attached at each end. The strap (26) comprises a plurality of longitudinally extending multi-filament cables or ropes (2) arranged in a substantially planar array embedded in an elastomeric material (4). The cables or ropes (2) have a coating of primer for creating a bond with the elastomeric material (4). The primer may be restricted to the external surface of the cables or ropes (2), or some of the surfaces of the filaments may be free of primer. This facilitates relative movement of the filaments during flexure or compression of the strap (26). Moreover, an extrusion process for manufacturing the strap (26) including a priming station (12) is disclosed.
Abstract:
A high traction synthetic rope comprising a braided sheath (8) adhered to a synthetic strength member (7) by means of a first synthetic portion (9) and portions of material (23) adhered to the outside surface of the braided sheath by means of a second synthetic portion (21), where the portions of material (23) are formed of a substance that differs from a substance mainly forming the second synthetic portion (21) and exhibits greater friction when wet or with greasy conditions and measured on an iron surface than does the substance mainly forming the second synthetic portion. Also methods of manufacturing such a high traction synthetic rope are disclosed. The rope shows reliable traction on driven rotating elements during wet / greasy conditions.
Abstract:
There is disclosed a method of forming an eye end termination on a rope having a core comprising a plurality of multi-strand subropes, and a rope having a core comprising a plurality of multi-strand subropes and at least one eye end termination. In one embodiment, a method of forming an eye end termination (16) on a rope (10) having a core (12) is disclosed. The rope comprises a plurality of multi-strand subropes (14) each of a first strength, and the method comprising the steps of: coupling a pair of subropes ( 14) in the rope core ( 12) together using a multi-strand coupling rope ( 18) of a second strength which is greater than said first strength, to thereby form at least part of the eye end termination (16). The step of coupling the pair of subropes (14) together comprises splicing a first portion of a coupling rope (18) to one of the subropes in the pair of subropes, and splicing a second portion of the coupling rope to the other one of the subropes in the pair of subropes.
Abstract:
본 발명은, 가교결합된 실리콘 중합체의 코팅을 포함하는 고강도 섬유, 및 상기 섬유로 제조된 로프에 관한 것이다. 상기 섬유는 바람직하게는 고성능 폴리에틸렌(HPPE) 섬유이다. 가교결합된 실리콘 중합체를 포함하는 코팅은, 가교결합성 실리콘 중합체를 포함하는 코팅 조성물로부터 제조된다. 상기 로프는, 굽힘 용도(예컨대, 사이클릭 벤드-오버-시브 용도)에서 상당히 개선된 서비스 수명 성능을 나타낸다. 본 발명은 또한, 굽힘 피로 내성의 개선을 위한, 로프 중의 가교결합된 실리콘 중합체의 용도에 관한 것이다.
