ANTIABRASION CURVED SECTION AND METHOD OF MANUFACTURE

摘要

Antiabrasion curved section (1) made of reinforced curved plastic material and comprising only in its lower portion (4) and/or its upper portion (6) and antiabrasion material. A plurality of antiabrasion sections are produced inside a profiled mould (5) with a plurality of grooves wherein there is arranged the antiabrasion material of the lower faces (4), then the reinforced filaments impregnated with stabilizable resin and finally the antiabrasion material of the upper faces (6). The mould is wound about a mandrel and the plastic material is stabilized before removing from the mould the sections which form a unitary assembly dividable particularly during the stranding of the armourings. The invention applies particularly to the fabrication of antiabrasion sections intended to be used in sheaving for flexible pipes.
