A process for manufacturing a tyre which has at least one structural element including at least one first portion made of a first crude elastomeric material, and at least one second portion made of the first crude elastomeric material, the second portion being axially spaced apart from the first portion. The process includes the steps of forming a crude tyre on a supporting device and moulding and curing the crude tyre, wherein the step of forming the crude tyre includes the step of providing the structural element. The step of providing the structural element includes: a) forming the first portion by winding at least one continuous elongate element made of the first crude elastomeric material by means of a roto-translational movement between the supporting device and an erogating device for supplying the continuous elongate element; b) starting to apply the continuous elongate element in a position axially spaced apart from the first portion while continuing supplying the continuous elongate element so as to form the second portion; and c) forming the second portion by winding the continuous elongate element made of the first crude elastomeric material by means a roto-translational movement between the supporting device and the erogating device. |
