Abstract
A process for building tyres employing a forming drum having circumferentially consecutive sectors that are radially movable between a contracted condition and an expanded condition in which the sectors are radially moved away from a geometric axis in order to define a radially external abutment surface. Each sector has circumferentially opposite coupling portions each having circumferential projections alternated with circumferential cavities. The projections of each sector are slidably engaged in the respective cavities of circumferentially adjacent sectors. From at least one of the projections, at least one support wing is extended having a first side and a second side that are respectively opposite. The first side coincides with a portion of the abutment surface and the second side at least partially overlaps one of the projections belonging to an adjacent sector.
