Process for manufacturing belted tires
Abstract
Abstract In the manufacture of ra dial ply tires having an annular multi-ply belt between the carcass crown and tread, a cylindrical casing is first prepared and a first belt ply is placed annularly about the casing while it is still in cylindrical form, i.e. prior to toroidal shaping. An incomplete belt assembly with one less ply is prepared, and annularly surrounded by a tread member. Subsequently the tread and incomplete belt assembly are placed annularly about the casing and first belt ply is expanded to force the first belt ply radially outward into contact with the remainder of the belt and tread assembly to complete the shaped raw tire. Finally, the completed assembly is cured by conventional methods to mold the components into a unitary belted tire structure.
