Abstract: A method for assembling veneer sheet into a plywood comprising the steps of supplying the veneer sheets to a feed conveyer, stopping the veneer sheet so that the forward edge thereof is precisely oriented in the transverse direction perpendicular to the feed direction, detecting the position of the veneer sheet in the transverse direction and calculating deviation thereof from a reference line extending along the feed direction by a computer, and transporting the veneer sheet by a transfer unit to a position on an assembling conveyer for fabricating a stepped lamination. The assembling conveyer extends parallel to the feed conveyer and is operated intermittently. The transfer unit includes a holding member for holding the veneer sheet during the transportation and is controlled by the computer for correcting the deviation while transporting the veneer sheet.
