ABSTRACT:
As a preparatory step to rigid substrate application, indefinite length strips of wood veneer are tenderized by cross-grain stressing through a roll nip wherein the surface of a steel roll is corrugated with circumferentially extending flutes bearing against the veneer strip and backed by a medium hard rubber roll. Such treatment fractures the natural, transverse or cross-grain fiber in the veneer along longitudinal strip increments of the veneer surface.
