Abstract
A method of making and shaping tires, by means of a drum consisting of two rotating, coaxial and sliding discs relative to each other, each disc being provided with a radially expandable annular seat capable of housing one of the tire beads, comprising the following phases: - apply frame fabrics to the drum while the discs are at the distance corresponding to the longitudinal development of the frame between rim and rim on the finished tire, - application of the rings around the frame fabrics in correspondence of said annular seats of the discs, sealing of the rings to the frame fabrics by radial expansion of said ring seats, - free shaping of the frame by the reciprocal approximation of the two discs and the simultaneous introduction of a fluid directly into the frame fabrics in the space delimited by the two movable discs. - application of the eventual sealing intermediate and of the tread on the shaped frame; - bending of the edges of the framework fabrics around the hoops, essentially characterized by the fact that said bending is carried out by exerting on the lateral portions of the frame a force, directed towards the interior of the frame, which remains while the reciprocal distance of the rings, which are solidly housed in said seats, is carried at the value of the tire at the end of its vulcanization, said force also remains until the knee of the eventual sealing intermediate and the tread are completed.
