Abstract
Abstract A continuous press for pressing glue-coated press charges includes a pair of cooperating press belts each comprising a pair of endless support members transversely mounting a plurality of press platens, with associated underlying anti-friction roller belts. Each press platen is of floating laminar construction. An endless caul belt overlies each press belt, arranged for protective contact with the press charge and preventing mutilation of its surface. A ratchet drive advances the belts in coordinated, step-wise increments determined by measuring means associated with the ratchet drive means and measuring the lineal progress of the work through the press. Side rolls guide the press belts as they travel the length of the press.
