Abstract
A plurality of abrasive sleeves (3) surround a wire rope (2) and are spaced at predetermined intervals longitudinally of the wire rope. An elastic material (4) of rubber such as natural rubber is formed between the abrasive sleeves in such a manner as to surround the wire rope. A rubber/metal bonding agent (7) such as chlorinated rubber type bonding agent is used to effect vulcanization bonding between the opposite end surfaces of each abrasive sleeve and the elastic material and between the wire rope and the elastic material. The ends (19) of the wire rope are connected together by a combination of end connecting members (5, 6a) provided with male threads (17, 17a) and fixed to the ends of the wire rope and on internally threaded connecting sleeve (30), whereby a closed loop is formed.
