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. DURING LAMINATING, A SILICONE RUBBER LAYER IS INCLUDED BETWEEN THE OVERLAY SHEET AND THE UPPER CUAL PLATE. 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 SECTIONS, AND MAY EVEN BE UNDERCUT. IN ADDITION, THE DEPRESSED PORTIONS OF THE LAIMNATE SURFACE ARE FULLY CONSOLIDATE. THE SILICONE RUBBER MAY BE REUSED.
