    Abstract: A rope including polyethylene elongate elements oriented in the length direction of the rope, where for at least part of the elongate elements the distance of the element to a central longitudinal rope axis varies over the length of the rope. The polyethylene elongate elements including tapes of ultra-high molecular weight polyethylene, the tapes having a width to thickness ratio of at least 10 and a polymer solvent content below 0.05 wt. %. The distance of at least part of the elements to the central longitudinal rope axis varies over the length of the rope between a longitudinal line which is at most 30% from the outside of the rope and a longitudinal line which is at most 30% from the central longitudinal axis of the rope. Such a rope shows a high strength-strength ratio (the ratio between the strength under use conditions and the fresh strength of the rope).

    Abstract: A reinforcement cable is formed of an assembly of strands. Each strand is formed of two wires wound around each other in the same direction, with a constant pitch whose length is less than 300 mm. The two wires have linear contact with each other in the form of a helix. These helices have the same direction and the same constant pitch length. The assembly is formed of two strands of the same length of pitch and wound in opposite directions and/or it is formed of two to four strands such that the assembly has the same length of pitch and wound in the same direction as one strand and, with respect to another strand, a different length of pitch and/or wound in an opposite direction.

    Abstract: A coreless glass fiber cable is made of a plurality of individual substantially untwisted glass fiber rovings twisted together. Certain of the rovings are impregnated with one component of an elastomeric resin with the remainder of the rovings impregnated with the second component of the elastomeric resin. The impregnated rovings are spirally twisted together in the same direction at substantially the same helical angle, the two components of the elastomeric resin impregnating the rovings mixing with each other at the junction of the intertwining of the rovings to form a cured elastomer spacing the glass fiber rovings and filaments making up the rovings from each other. The layed up glass fiber cable is fed back on itself and subsequent layers of impregnated rovings plied together over the initial layers. The subsequently applied layers are applied at the same helical angle as the initial layer. The cable, although useful for other purposes, is particularly useful in the manufacture of endless track for track vehicles, the endless track comprising a plurality of individual track sections strung along a cable of the type mentioned.
