The process comprises providing at least one elongated element (15) comprising at least one metallic wire (11) twisted together with at least one textile yarn (20) and removing said at least one textile yarn (20) from said at least one elongated element (15) to form the aforementioned metallic reinforcing cord (10). Such a metallic reinforcing cord (10) has a helical geometry, consisting only of said at least one metallic wire (11) that extends along a helical path. The invention also relates to an apparatus (1) for manufacturing the aforementioned metallic reinforcing cord (10).
Process for manufacturing a metallic reinforcing cord for tyres for vehicle wheels, comprising:
Process according to any one of the previous claims, wherein said at least one textile yarn (20) is made of a water-soluble material.
Process according to any one of the previous claims, wherein said at least one elongated element (15) comprises at least two metallic wires (11) twisted together with said at least one textile yarn (20).
Apparatus (1) for manufacturing a metallic reinforcing cord for tyres (100) for vehicle wheels from at least one elongated element (15) comprising at least one metallic wire (11) twisted together with at least one textile yarn (20), the apparatus (1) comprising a removal device (70) configured to remove said at least one textile yarn (20) from said at least one elongated element (15) to form a metallic reinforcing cord (10) in which said at least one metallic wire (11) extends along a helical path.
