ABSTRACT:
Apparatus and method for curing sheet rubber by radiation of microwave energy. The sheet rubber is wrapped around a metal cylinder forming a roll with a layer or liner of microwave transparent material separating the adjacent rubber layers. The ends of the roll are shielded from microwave energy by metal disks which support the cylinder. The disks sit between rollers of a roller conveyor which is activated to provide the result of rotating the roll for uniform heating in a microwave field.
