ABSTRACT:
A veneer sheet having lathe checks is pressed in at least one of two opposite directions in the same plane as the veneer sheet itself and substantially perpendicular to the directions of its fibers, while another sheet is being bonded to at least one of its two oposite sides, namely, its tight side having no lathe checks and its loose side having the lathe checks. Before the veneer sheet is pressed in this manner, glue may or may not be filled into the lathe checks thereof. Or glue is filled into the lathe checks of the veneer sheet, and is merely hardened, without bonding no other sheet thereto, while the sheet is being pressed in at least one of the foregoing two opposite directions.
