Plant for building tyres for vehicle wheels

A plant for building tyres for vehicle wheels, comprising:

• a crown structure building line for building crown structures on respective second stage forming drums, said crown structure building line comprising
• a first path, which starts in a first initial location and ends in a first final location, for building a first part of components of the crown structure, the first part comprising at least one belt layer, and
• a second path, which starts in a second initial location and ends in a second final location, passing through a first intermediate location and a second intermediate location, for building a second part of components of the crown structure, the second part comprising at least a tread band;
• a carcass structure building line for building carcass structures on respective first stage forming drums from a third initial location to a third final location, passing through a third intermediate location;
• a shaping and assembly station comprising a first loading/unloading device, a second loading/unloading device and a shaping and assembly machine with a shaping drum;
• a first manipulator having a working area inside which the second initial location, the second final location, the first intermediate location and the second intermediate location of the second path of the crown structure building line and the first loading/unloading device are located;
• and
• a second manipulator having a working area inside which the third final location and the third intermediate location of the carcass structure building line and the second loading/unloading device are located,
• wherein:
• the first manipulator is configured to
• transfer the second stage forming drums, carrying respective crown structures being processed, from the second initial location to the first intermediate location of the second path of the crown structure building line, and
• manage the second stage forming drums arriving into the second intermediate location, carrying the respective crown structures, by delivering the crown structures to the first loading/unloading device and the respective second stage forming drums to the second final location;
• and
• the second manipulator is configured to manage the first stage forming drums arriving into the third intermediate location, carrying the respective carcass structures, by delivering the carcass structures to the second loading/unloading device and by bringing the respective first stage forming drums to the third final location.
