in which: each R1, R2 and R3 group represents, independently of one another, an alkylene, arylene, arylalkylene, alkylarylene or cycloalkylene group, each X.sub.1 and X.sub.2 group represents, independently of each other, COOH, CONHOH, SOOH, PO(OR)(R) or PO(OR)(OR) with R and R representing, independently of each other, hydrogen or an alkyl group, and X.sub.3 comprises at least one COOH, CONHOH, SOOH, PO(OR)(R) or PO(OR)(OR) group with R and R representing, independently of each other, hydrogen or an alkyl group.

The present invention provides a production method for a closed-loop cable. The method includes the steps of providing a cable including a core and metal strands helically wound around the core, connecting two ends of the cable in splice areas via splice knots formed by ends of each metal strand, inserting the metal strand ends inside the cable after locally removing the core and subsequently overmolding each splice area using a polymer.

A wire rope formed from a resin core and six strands, the resin core having an inner core with a circular cross section and an outer layer built up on the periphery thereof. The outer layer has a melting temperature lower than that of the inner core. The six strands are twisted together helically on the periphery of the resin core in an intertwining die in such a state that gaps are assured between the strands. The resulting wire rope is heated in a heating unit at a temperature higher than the melting temperature of the outer layer but lower than the melting temperature of the inner core. The wire rope is formed by subsequently compressing the six strands from the periphery thereof in a compressing die. The molten outer layer is hardened by natural cooling, after which the wire rope is taken up.
