Abstract

A process and an apparatus for building tyres and a tyre for vehicle wheels are described. A substantially cylindrical carcass sleeve, having at least one carcass ply, is formed by laying consecutively adjacent strip-like elements one after the other around the circumferential extension of a substantially cylindrical deposition surface. Circumferentially consecutive strip-like elements are laid one after the other to form overlap zones along respective longitudinal edges superimposed on each other. Each overlap zone has, along a longitudinal extension thereof, terminal sections that are laterally opposite with respect to an intermediate section. The intermediate section of each overlap zone has greater width than the width of the terminal sections.
