ABSTRACT:
Apparatus for continuously processing wood product formed from random lengths of wood strips assembled in face-to-face relationship with heat curable adhesive applied to adjacent contacting faces of the strips includes a pair of opposed, parallel, linear arrays of electrically insulative blocks, the linear arrays of blocks having inner, confronting faces spaced apart transversely to define an elongated, longitudinally extending press zone into which the product is adapted to be fed. A drive motor is coupled to each linear block array for moving the arrays in the same direction in unison to thereby advance the stock in the press zone. An adhesive RF curing zone substantially coextensive with the press zone is defined by the inner confronting faces of the block arrays and first and second elongated, parallel RF electrodes disposed between the confronting inner faces of the block arrays. At least the first electrode having inner and outer surfaces is disposed in its entirety within the confines of the press zone. A longitudinally extending bar of insulative material may be attached to the outer surface of the first electrode.
