Abstract

The method involves pressing the series of sheets so that the sheets lie flat, and passing them through a high frequency or MW heating path to heat them to the curing temperature of the glue used. The heated series of sheets is then pre-pressed at 5 to 30 bar surface pressure, or 3 to 10 N/mm line pressure. The sheets are then pressed in a continuous press until the final thickness is reached. An independent claim is included for a system for preforming the method.
