ABSTRACT:
Bundles of presized wood veneer strips are prepared for longitudinal edge adhesive by vertical alignment of the veneer strip face planes on a horizontal machine bed surface between open clamp jaws. Upon satisfactory alignment of the strip edges on the bed surface, the clamp jaws are closed on the bundle and translated from the bed surface to an adhesive transfer roll transverse plane. As the roll traverses the bundle length, adhesive is coated upon the veneer strip bottom edges. After completing the adhesive application pass, the clamp jaws are opened on manual command to release the veneer strip bundle for manual inversion. While the clamp jaws are open, the adhesive transfer roll is returned to the starting position. The clamp jaws are manually returned to the bed surface position and the opposite edge set of the inverted bundle is aligned against the bed surface and the process is repeated. After the adhesive has dried, individual strip pairs are joined in a common plane along longitudinal edges under simultaneous compressive pressure and adhesive curing heat.
