Antiabrasion curved shape and process for its manufacture

摘要

Antiabrasion curved section made of reinforced curved plastic material and comprising in at least one of a lower portion and an upper portion an antiabrasion material. A plurality of antiabrasion sections are produced inside a profiled mold having a plurality of grooves in which is arranged the antiabrasion material of the lower faces. Reinforced filaments impregnated with a stabilizable resin are supplied to the mold and, finally, the antiabrasion material of the upper faces is applied. The mold is wound on a mandrel and the plastic material is stabilized before removing the mold sections which form a unitary assembly dividable particularly during the stranding of arm rings.
