Abstract
A method for controlling the discharge of fluids during a process for vulcanization and molding of a green tire includes the steps of: building at least one portion of a radially internal surface of a green tire by winding of a continuous elongated element of elastomeric material into a plurality of coils confining circumferential grooves along the rolling direction of the tire; disposing the circumferential grooves into fluid communication with discharge channels present in the radially external surface of a pressing bladder disposed in a radially internal cavity bounded by the green tire.
