Abstract
In manufacturing pressed boards, a flowable mixture of thermosetting resinous material and filler is blown through one or more nozzles into a converging throat formed by a pair of relatively inclined perforated conveyor bands in which the mixture is compacted into a continuous, coherent and self-supporting web by the application of heat to preset the resinous material thereof. The web is transversely cut into individually manipulable sections which are fed by a stack conveyor to a platen press, operating in step with the feeding and cutting mechanisms, for final setting of the resin.
