ABSTRACT:
The method of surface treatment of wooden panels which comprises drawing off carrier strips or sheets impregnated with hardenable synthetic resin from supply rollers, and laying the strips onto the top and bottom surfaces of the panel. The sheets are attached to the panel along the edges thereof by heat-bonding, using a heated tool which presses the strip to the corner formed by the intersection of the surface of the wooden panel with the perpendicular side edges thereof. The wooden panel, with carrier sheets attached thereto along its edges, is then placed in a heated press, where the sheets are pressed and heat-bonded to the surfaces of the panel.
