Abstract: An apparatus for the production of a continuous rubber strip which is molded with surface designs, such as tire treads, in the uncured state and then cured, after removal from the mold, by heat or radiation is disclosed. In the apparatus the extruded rubber strip is passed between cooperating mold segments carried by respective endless belts which, along with related components, apply suitable temperatures and pressures to the strip to product the surface designs. The molded uncured rubber strip is removed from the molds and then completely cured by radiation and/or heat.

Abstract: An apparatus and processes for the production of a continuous rubber strip which is molded with surface designs, such as tire treads, in the uncured state and then cured, after removal from the mold, by heat or radiation is disclosed. In the apparatus the extruded rubber strip is passed between cooperating mold segments carried by respective endless belts which, along with related components, apply suitable temperatures and pressures to the strip to produce the surface designs. The molded uncured rubber strip is removed from the molds and then completely cured by radiation and/or heat. Process embodiments are also disclosed wherein partial curing of the rubber while in the molding apparatus is performed.
