Abstract

Abstract An elongated plywood panel and a method for producing the same. Elongated continuous face, back and intermediate veneer sheets are formed by joining multiple sheet sections end-to-end, such sheet sections having grain extending longitudinally of the veneer sheets formed. Contiguous ends of adjacent sheet sections in a veneer sheet are chamfered in reverse directions, and these are overlapped in the sheet. The ends are joined with thermosetting glue, which is set by applying heat and pressure thereto. The joints between sheet sections in a veneer sheet thus formed extend transversely of the veneer sheet. The continuous face, back and intermediate veneer sheets are moved longitudinally, in spaced face-to-face relation, along adjacent flow paths, with the joints between sheet sections in each veneer sheet spaced along the flow path from similar joints in other veneer sheets. Core sheets with thermosetting glue applied to their opposite faces are interposed between the veneer sheets. The veneer and core sheets then are heated and pressed together to set the glue. The paneling produced may then be cut to a desired length.
