Abstract

Press for consolidating and curing large panels coated on one or both faces with a fluid resin, where the upper platen is designed to first make a linear contact zone with the resin coated surface and then to progressively develop the contact zone to the edges to the panel. The press is used for the mfr. of panels or laminates impregnated or sheathed with thermosetting resin or thermoplastic melts or pastes. Air between the panel surface and the platen is progressively expelled to avoid surface blemishes due to trapped air bubbles etc.
