<p>A liner compound curing apparatus (20) which includes a conveyor which passes through a high frequency or radio frequency ('RF') induction heating system (22). The induction heating system (22) includes at least one elongated coil and may use a pair of spaced apart elongated coils. The curing apparatus (20) passes the container ends (24) in close proximity to the induction heating system (22) for maximizing the inductive coupling between the heating system (22) and the container ends (24). The conveyor uses a foraminous belt (26) which is positioned between induction coils of the RF heating system (22). The foraminous belt (26) is driven generally co-axially relative to the elongated coils. A vaccum system is coupled to the curing apparatus (20) to draw a vacuum (48) on the container ends (24) positioned on the belt (26) to pull air through the foraminous belt (26) allowing sufficiently close positioning of the container ends (24) relative to the heating system (26). The curing apparatus (20) provides a substantially shorter operating length compared to prior art thermal oven systems and provides the benefit of minimizing detrimental thermal effects on the container end (26) and the liner compound.</p> |
