Abstract
Rigid synthetic foam is expanded, molded and cured in an endless mold formed by opposed spaced horizontal belt conveyors with side dams. To obtain a smooth finish on the products, a top cover belt and a bottom cover belt are employed to span the rigid slats of the conveyors, respectively. The top cover belt is stretched tightly and smoothly when the endless conveyors approach each other at the entrance to the pressure mold, by means of a downwardly depending continuous wedge shaped member along each side margin of the cover belt that cooperates with an upwardly opening correspondingly wedge shaped recess in the side dam. To obtain different thickness products, spacer blocks may be employed between the side dam and the lower conveyor.
