Method, process and plant for controlling the manufacture of tyres for vehicle wheels

A plant for controlling building of a tyre for vehicle wheels, comprising:

• a building line for building a carcass structure on a forming drum;
• and
• a station for assembling the carcass structure to a crown structure, wherein the building line for building the carcass structure comprises:
• an intermediate forming line for manufacturing an intermediate portion of the carcass structure on a respective forming drum, wherein the respective forming drum is configured to move in opposite rectilinear directions along a shuttle guide within the intermediate forming line, said intermediate forming line comprising a first transfer location, and wherein the shuttle guide is rectilinear along an entire length of the shuttle guide;
• n completion locations with n>1 for completing the intermediate portion of the carcass structure;
• a second transfer location in which the carcass structure is made available for subsequent assembling to the crown structure by unloading the carcass structure from the respective forming drum;
• and
• a handling device movable along a first trajectory for receiving the respective forming drum from a first shuttle and transferring the respective forming drum to each completion location by moving along the first trajectory;
• the first shuttle movable between the handling device and the first transfer location;
• and
• a second shuttle for transferring the respective forming drum from the handling device to the second transfer location, the second shuttle being movable between the handling device and the second transfer location along a second trajectory, wherein the first and second shuttles are configured to carry the respective forming drum to the first transfer location and second transfer location, respectively, in cantilevered fashion by holding a terminal end of a central shaft of the respective forming drum,
• wherein, when the first transfer location is occupied by a forming drum coming from the intermediate forming line or intended for the intermediate forming line, there are one to n locations selected from the n completion locations and the second transfer location that are occupied by respective forming drums,
• wherein the second trajectory intersects the first trajectory, and
• wherein the first trajectory and the second trajectory are rectilinear.
