Abstract: A cover veneer 17 is lightly glued, face side down, to a chipboard 24, and overlayed by a rigidly glued, cross grain oriented veneer layer 18. Opposing grooves 25,26 are simultaneously cut into the veneer layer 18 and board 24, respectively, to define adjacent accordion folding panels 11-15, and recess 21 are provided around the grooves 26 to accommodate pliable hinge strips 19,20. The veneer unit 17,18 is then removed from the board, the board and unit are reversed, the hinge strips are inserted in their recesses, and the board and unit are then firmly bonded together with the grooves 25,26 aligned. Grooves 22 and V-shaped notches 23 are then cut through to the grooves 25,26, respectively, leaving just the hinge strips to hold the panels together.In an alternate embodiment, the veneer layer 18 is replaced with a continuous pliable web of plastic fleece 27, which also serves as the hinge strips.
