Process for making a reinforcing cord for tyres for vehicle wheels

Abstract

A process for making a reinforcing cord for tyres for vehicle wheels comprises providing at least one semi-finished product (15) comprising at least one sacrificial elongated element (20) and at least two elongated elements (11a, 11b) made of non-metallic material, wherein said at least one first elongated element (11a) of said at least two elongated elements (11a, 11b) and said at least one sacrificial elongated element (20) extend along a helical path with a predetermined helix pitch (E), and removing the at least one sacrificial elongated element (20) from the at least one semi-finished product (15). A reinforcing cord (10) is thus obtained having an empty space (10a) previously occupied by the at least one sacrificial elongated element (20) and wherein said at least one first elongated element (11a) extends together with said empty space (10a) along said helical path with said predetermined helix pitch (E).
