METHOD FOR MANUFACTURING A TYRE ON A RIGID SUPPORT USING RUBBERY PRODUCTS, APPLYING APPARATUS ACCORDING TO SUCH A METHOD AND MACHINE USING SUCH AN APPARATUS

摘要

The rubber products forming a part of the structure of a tire are laid onto a rigid core by means of a volumetric extruder having an outlet orifice of small size positioned close to the surface on which the rubber is to be applied. The rubber products are built up by a meridian displacement of the orifice relative to the receiving surface with the extrusion of a controlled volume of rubber.
