ABSTRACT:
Trays carrying hot-pressed boards, coming from a platen press, are delivered by an input conveyor to a cooling rack comprising an endless vertical transporter with chain-supported radial arms forming peripherally separated tray-receiving stages, the boards being stripped off the oncoming trays and being temporarily retained on the input conveyor as the trays advance into stages then aligned therewith. Upon the loading of each tray into a transporter stage, the board previously stripped therefrom is released and passed by the input conveyor on through a clearance between successive stages on the ascending side of the slowly moving transporter into the nip of a set of feed rollers which drive that board through a similar clearance on the descending side onto an output conveyor. The empty trays, after passing around the upper vertex of the transporter to the descending side, are intercepted either by the output conveyor receiving the boards or by another outgoing conveyor overlying the latter for removal from the cooling rack and recirculation to the press via a loading station. Each conveyor is divided into several endless bands offset from the orbits of the radial transporter arms, the bands being located on a level near the lower vertex.
