ABSTRACT:
A duel-belt press in which two mating endless steel belts are supported and pressed against each other through a treating zone while holding a layer of a product captive. The layer of product is compressed as it moves into the nip formed by two diametrically opposed compression rolls which act through the belts to compress the product layer. Belt support structures are provided through the zone extending from upstream to downstream of the compression rollers relative to the movement of the belts and the layer of the product.
