ABSTRACT:
A flexible screen mounted to pneumatically seal the sides of an opposing belt conveyor system in a porous pack curing oven. Fixed to the upper belt structure and drapingly sealed to the lower belt structure, the screen impedes curing gases directed through the foraminous belts and porous pack therebetween from exiting through the edges of the pack. The draping screen provides a seal over a range of belt-to-belt spacing.
