Una realización preferente aunque no limitativa de la invención, consiste en el transporte, en una máquina de contracolado, de una hoja inferior, preferentemente de cartón, mediante un alimentador, hacia un elemento de encolado de la máquina de contracolado. En el elemento de encolado se mantiene una cola de almidón fría en forma líquida y se aplica, mediante un cilindro de aplicación, sobe el lado superior de la hoja inferior. La hoja inferior, recubierta con la cola de almidón, es transportada a continuación a una estación de orientación a la que se suministra, mediante otro alimentador, una hoja superior cuyo lado visto está litografiado. En la estación de orientación, se unen la hoja inferior y superior y, a continuación, se encola mediante compresión. El producto contracolado así obtenido se transporta a la estación de secado dotada de unas placas calefactoras que transmiten el calor a dos cintas transportadoras entre las que está depositado el producto contracolado, la superior de poliéster y la inferior de paño textil, que permiten el secado completo del contracolado. A preferred but non-limiting embodiment of the invention consists in the transport, in a plywood machine, of a lower sheet, preferably of cardboard, by means of a feeder, to a gluing element of the plywood machine. A cold starch glue is maintained in liquid form in the sizing element and applied, by means of an application cylinder, on the upper side of the lower sheet. The lower sheet, coated with the starch glue, is then transported to an orientation station to which, by another feeder, an upper sheet is provided, the side of which is seen lithographed. In the orientation station, the lower and upper sheet are joined and then glued by compression. The contracolado product thus obtained is transported to the drying station equipped with heating plates that transmit the heat to two conveyor belts between which the contracolado product is deposited, the superior one of polyester and the inferior one of textile cloth, which allow the complete drying of the plywood.
