METHOD, PROCESS AND APPARATUS FOR MANUFACTURING TYRES FOR VEHICLE WHEELS

摘要

In an apparatus for building tyres for vehicle wheels, a forming drum (13) is loaded on a shuttle (17) movable on a guide (16) along a deposition line (L). The shuttle (17) is moved on the guide (16) in the two running directions (SI, S2) to bring it to dispensing stations (19, 20, 21; 22, 23, 24, 25, 26) of semifinished products (4a, 4b, 5; 22a, 23a, 24a, 25a, 26a) disposed in at least some deposition locations (18i, 18ii, 18iii, 18iv, 18v, 18vi) positioned in space succession along the deposition line (L). At each of the dispensing stations (19, 20, 21; 22, 23, 24, 25, 26), at least one semifinished product (4a, 4b, 5; 22a, 23a, 24a, 25a, 26a) is laid on a radially external surface (13a) to the forming drum (13) carried by the shuttle (17) for forming at least one component of a tyre (2). The shuttle (17) is moved on the guide (16) in a different sequence from the space succession of the depositions locations (18i, 18ii, 18iii, 18iv, 18v, 18vi) along the deposition line (L).
