Abstract
A method of manufacturing road vehicle tires, whereby a toroidal forming mold, housing a finished green tire, is fed successively through a first preheating station where peripheral heating elements preheat the tread portion of the green tire; through a second curing station where the tire is cured; and through a third postinflation station where the tire, fitted to a tubular support and removed from the mold, is engaged by a cooling element for cooling the bead portions of the tire.
Claims6
A road vehicle tire manufacturing method comprising the steps of successively feeding a toroidal forming mold completely housing a finished green tire having a bead portion and a tread portion through a first preheating station wherein first heating means are connected to the forming mold for preheating only the bead portion and tread portion of the green tire;
- thus feeding said mold through a second curing station spaced apart from the first preheating station wherein the mold is connected to a curing unit pending completion of the curing process, and then feeding said mold through a third postinflation station spaced apart from the second curing station wherein the tire is engaged by means for cooling the bead portions of the tire.
