A core-sheath rope can include an outer sheath provided in the form of a hollow braid and an inner sheath provided in the form of a hollow braid, wherein thread changes between threads of the inner sheath and threads of the outer sheath and/or enlacements between threads of the inner sheath and threads of the outer sheath are provided in certain places. The rope can be characterized in that bridge threads extending in the longitudinal direction of the rope are provided in the places of the thread changes and/or enlacements, with the threads of the outer sheath and the inner sheath, respectively, which change from the inside to the outside and from the outside to the inside, respectively, being guided around those bridge threads.

A core-sheath rope, comprising a textile core with one or several stationary threads extending in the longitudinal direction of the rope, an outer sheath provided in the form of a hollow braid, and an inner sheath provided in the form of a hollow braid and surrounding the textile core. The rope is characterized in that at least part of the stationary threads of the textile core are braided individually into the hollow braid of the inner sheath.

Disclosed herein are methods for producing core-sheath structures by shaping at least one filament bundle containing a plurality of filaments to form at least one shaped strand of filaments, and braiding a plurality of strands, including the at least one shaped strand of filaments, over a core to form the core-sheath structure containing a braided sheath of the strands surrounding the core, wherein the shaped strand of filaments is an untwisted strand having a twist level of less than 1 turn per meter, a cross-sectional aspect ratio of the shaped strand of filaments is at least 3:1, as measured in the braided sheath, a thickness of at least a portion of the braided sheath ranges from about 10 to about 200 μm, and the braided sheath comprises a synthetic fiber having a tensile strength of greater than 12 cN/dtex. Also disclosed herein are core-sheath structures formed by such methods.

This application relates to cable assemblies with an outer (exterior) layer formed from braiding materials together. To achieve a desired pattern, a machine tool forming the outer layer undergoes several modifications. For a machine tool with two tracks (e.g., inner and outer track) with multiple carriers of material to be braided, each carrier position may include multiple bobbins, with each bobbin carrying a spool/coil of the material. During a braiding operation performed by the machine tool, each track rotates in opposite directions. Moreover, some bobbins include an arm that guides the material in a particular manner. For example, during rotation of the track, the arm provides a swinging motion, causing the material carried by the arm to move in a periodic (e.g., sinusoidal) motion. An additional track may be used to guide the arms.

The invention relates to a rope (1) made of textile fibre material, which is characterized by the combination of features whereby

a) the load-bearing fibre material of the rope (1) consists of high-strength synthetic fibres

b) the rope (1) is in the form of a spiral strand rope

c) the rope (1) has at least two, preferably at least three concentric load-bearing strand layers (3,4,5)

d) the individual strands (7,8,9,10,11,12) of the strand layers (3,4,5) are movable with respect to one another

e) the degree of filling of the rope (1) with textile fibre material is ≧75%, preferably ≧85%

f) the outermost ply (5,6) of the rope has a coefficient of frictionμ with respect to steel of μ<0.15.

This application describes a braided cord containing a braided sheath and optionally a core surrounded by the braided sheath. The braided cord has changing cross-sectional area ranging from 0.0004 mm.sup.2 to 30 mm.sup.2 and contains one or more sections having a tapering angle ranging from 1° to 60° when observed in one direction along the cord axis. The change in the cross-sectional area of the cord can be achieved by changing the thickness of the braided sheath and/or changing the cross-sectional area of the core when the core is present. The thickness of the braided sheath can be adjusted by changing the size and/or twist level of one or more sheath strands, changing the pick count of the braided sheath, and/or using one or more shaped sheath strands. This application also describes a process of producing the braided cord with changing cross-sectional area.

A tow cable for a decoy on a fast jet aircraft is described. The tow cable has a composite structure with a high friction fibre outer containment braiding, and low friction fibre internal strength members. Additional to these internal fibres may be electrical conductors and optical fibres. The whole composite providing a tow cable with high towing endurance and reliable in-flight performance, for flight profiles including high performance manoeuvres and in-flight refuelling.

A coupling device comprising a flexible elongate member of at least one length of an at least twice wound rope and a pin configured to be removably engaged with the flexible elongate member, wherein the flexible elongate member is formed as a loop or a part loop completing the loop with the pin, wherein at least one winding of rope is of disparate length to at least one other winding.

A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a plurality of basalt fibers to enhance temperature resistance of the tension member. A jacket material at least partially encapsulates the plurality of tension members. An elevator system includes a hoistway, an elevator car located in the hoistway and movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a plurality of basalt fibers to enhance temperature resistance of the tension member. A jacket material at least partially encapsulates the plurality of tension members.

A hoisting member for an elevator system includes a core having strength components embedded in a matrix material. A coating can surround the core to protect the core and control the coefficient of friction of the outer surface based on a range of desired friction properties to prevent or inhibit slippage of the hoisting member when used in a traction elevator system. The strength components may be made from carbon nanotube material with the matrix material made from a polymer material. The hoisting member may also include other conductive material or fiber optic material. The hoisting member may also serve as the trailing cable in an elevator system. In doing so the hosting member transmits power and data between the elevator car and the elevator controller thereby eliminating the need for a traditional trailing cable.
