The cable coiling device automatically coils heavy-duty electrical cable into a coiled bundle having a predetermined coil diameter. This device matches the over/under coiling method used to manually coil cables that eliminate unnecessary twists and knots in cables. The cable coiling device has a first roller and a second roller that is angularly offset from the first roller. The angular offset adds a twist to the cable as it passes between the rollers. The device maintains the first and second rollers at a predetermined distance away from each other so that the cable does not slip out of the opening between the rollers. When the coil exits the rollers, the resulting cable is coil bundled and has a specific predetermined coil bundle diameter. Guide wheels positioned at specific locations guide the cable through the device, which prevents cable looping before and after the cable passes through the rollers.

A layer of wires is preliminarily stranded by a layer of strand-through holes, and a first strand cylinder is used for the second pressing and stranding. The next layer of special-shaped single wires is stranded through a second pre-stranding assembly, and then the last layer of wires is stranded through a main stranding mold, thus stranding a plurality of layers at the same time with a compact structure. The outer circumference of the guide roller matches that of the special-shaped single wire, avoiding the reduced quality of stranded cable. The first rotating connector is bowl-shaped and is provided with a layer of strand-through holes together with a structure in which a first pull rod is in fit with the rotating connector and a structure in which a second pull rod is in fit with the rotating connector.

A sling manufacturing apparatus for constructing a synthetic sling having a cover and a core, includes a frame defining a longitudinal frame axis, a yarn feeder assembly associated with the frame, a drive roller connected to the frame, a tailstock movably mounted to the frame, an idler roller movably mounted to the tailstock, and an idler actuator secured to the tailstock. The drive roller is drivable to draw yarn from the yarn feeder assembly and the tailstock is movable relative to the frame substantially parallel to the longitudinal frame axis. The idler roller is movable relative to the tailstock parallel to the longitudinal frame axis. The idler actuator is configured to move the idler roller from a loading position spaced a first distance from the tailstock to a tensioned position spaced a second distance from the tailstock, wherein the first distance is greater than the second distance.

Systems and methods are provided for forming a cable. In one embodiment, a system for forming a cable comprises a non-driven roll station having a plurality of rolls for forming a shape of one or more strands associated with a first layer of the cable. Movement of the plurality of rolls of the non-driven roll station occurs passively during travel of the one or more strands associated with the first layer of the cable. The system further comprises a driven roll station having a plurality of rolls for forming a shape of one or more strands associated with a second layer of the cable. The plurality of rolls of the driven roll station are actively driven to effect movement and speed of the one or more strands associated with the second layer of the cable.

A power paying-off cradle consisting of power paying-off component and framework. In the framework is a cavity with an upper opening; a wire tension balance mechanism is installed in the cavity; a displacement wheel is installed on the wire tension balance mechanism, and a position detector of the displacement wheel is installed on the inner side wall of the framework; a turning wheel is installed on the front top of the framework; a thread hole is installed in the front of the framework; wire on the paying-off spool enwinds the turning wheel and the displacement wheel successively and passes through the thread hole. The wire tension balance mechanism has damping effect on the displacement wheel. When the tension of the displacement wheel is greater than or less than the damping force, the displacement wheel moves in order to ensure consistency of the tension or the strain of wire.

The invention relates to a rope made of a textile fibre material for applications in which a diagonal pull may occur, characterized in that the rope is a core/sheath rope the core (1) of which and the sheath of which are composed essentially of a textile fibre material the core (1) of which is stranded and which exhibits a force-fitting winding with a tensile element (2, 2, 2) between the core (1) and the sheath.

In a tire the strength of steel cord and the resilience of rubber are a successful combination. However, in some specific areas of a tire, more elongation is expected from the steel cord, while still a sufficient degree of stiffness is expected. A steel cord is presented that has these properties. The steel cord comprises two or more steel elements that are twisted together. The steel elements comprise one or more steel filaments. In total the steel cord comprises N filaments, each with a cross sectional area A. When the steel elements are individualised out of the steel cord they show a helix pitch length of L.sub.o, while a single pitch has a centre line length of S. The inventive steel cord shows a P value of at least 50 newton, wherein P=NE (A/S).sup.2. Further methods are presented to produce this steel cord.

The present disclosure relates to a twisting system for twisting multiple conductors together. In one implementation, the twisting system may include a rotatable twisting head having multiple holders for individual conductors of a cable to be twisted, and a loading device for sequentially loading the holders with the individual conductors. The loading device may be configured to be displaced into a transfer position identical for all individual conductors for loading the twisting head, and the twisting head may be configured to rotate a free holder of the twisting head into a suitable receiving position for being loaded with an individual conductor. The present disclosure also relates to a method for loading a twisting head with individual conductors.
