ABSTRACT:
A symmetrical clamping device for producing bonded uniform panels from narrow strips of wood as well as laminated boards glued together. Includes two relatively long guide plates provided with appropriate linkage mechanism capable of exerting pressure to the entire surface being clamped while applying force to the ends in a direction that is perpendicular to that surface when actuated manually by way of appropriate jack screws disposed at each end of the guide plates or automatically by using power cylinders in combination with linkage and an end bolt incorporated therein, to insure participation of bondable material in the process of clamping and conformation to the surfaces of guide plates which may have a straight flat surface or an irregular shape so as to produce desired final product.
