METHOD FOR MANAGING A PROCESS FOR BUILDING TYRES FOR VEHICLE WHEELS AND BUILDING LINE

A method of managing a process for building tyres (2) for vehicle wheels between a steady-state operating condition and a drum change operating condition. During the steady state operating condition, it is provided to sequentially and cyclically move N drums (100) configured for a first size along a building path (30) comprising a first path (110), with N being an integer greater than or equal to 1. The movement along the first path (110) is carried out by moving, with a moving device (170), one of the N drums (100) configured for the first size at a time, coupled with a first pair of axially opposite support elements (101), said first pair of support elements (101) being coupled with the moving device (170) and being configured for said first size. During the drum change operating condition to a second size, it is provided to replace said first pair of support elements (101) with a second pair of support elements (201) configured for said second size. The invention also relates to a line for building tyres (2) for vehicle wheels operating according to a steady-state operating condition and a drum change operating condition.
