Abstract

Un procedimiento para fabricar una hoja a base de materiales sintéticos termoplásticos, térmicamente inestables, a una temperatura de por debajo de la gama termoplástico, para a continuación calentar la hoja hasta la gama termoplástico del material sintético empleado, caracterizado porque la hoja se calienta en la misma operación bajo tensión y orientación a la temperatura termoplástico del material sintético empleado.
