High pressure laminates with deeply embossed surface

Abstract

Abstract A HIGH PRESSURE LAMINATE WITH DEEPLY EMBOSSED SURFACE IS PRODUCED USING AS A DECORATIVE SHEET BENEATH THE OVERLAY, A RELATIVELY THICK ELEMENT OF VARYING CROSS SECTION, SUCH AS WOVEN CANE, LACE, OR A PAPER SHEET CONTAINING HOLES OF VARIOUS SHAPES. DURING LAMINATING, A THERMOPLASTIC LAYER IS INCLUDED BETWEEN THE PARTING SHEET AND THE UPPER CAUL PLATE, THE THERMOPLASTIC LAYER IS REDUCED TO THE FLUID STATE DURING THE LAMINATING OPERATION, AND THE RESULTANT LAMINATE IS FOUND TO BE DEBOSSED TO A DEPTH THAT IS SUBSTANTIALLY EQUAL TO THE THICKNESS VARIATION IN THE PLY OF VARYING CROSS SECTION. IN ADDITION, THE DEPRESSED PORTIONS OF THE LAMINATE SURFACE ARE FULLY CONSOLIDATED. THE PROCESS ENABLES ECONOMIC PRODUCTION OF DECORATIVE HIGH PRESSURE LAMINATES HAVING DEEPLY EMBOSSED SURFACES, WHICH ARE HIGHLY DESIRABLE TO ARCHITECTS AND FURNITURE DESIGNERS.
