ABSTRACT:
To reduce elongation of a stranded wire rope or cable (1), particularly when running over sheaves, or pulleys, and decrease vibration as well as operating noise while increasing operating speed, insert elements (4) are placed between adjacent rope elements (2). The insert elements, in cross-section, have an intermediate portion part (7) with oppositely positioned concave recesses (9), a head portion (6) which can be widened to the circumferential diameter of the rope or cable (1) and a widened base portion (8). The base portions (8) are not interconnected. The insert ribbons or tapes are preferably formed along their length with slits (11) extending from the head portion (6) to about the middle of the ribbon or tape to allow for bending of the rope, and the inserts about circular pulleys. The insert elements (64, 74, 94), preferably, are reinforced with a fabric material (16, 96), which is integrated into the material of the inserts, and located, for example adjacent the concave recesses, or in a central plane of symmetry, or with longitudinal reinforcements (84), such as reinforcement fibers, glass fibers, monofilaments or the like. Preferably, the fabric is a woven fabric of fibrous or monofilamentary material, yarns or threads.
