Abstract

Un procedimiento de moldeo de compuestos termoplásticos orgánicos exentos de disolvente que comprende el ablandamiento por calentamiento de dicho compuesto su extrusión a alta temperatura por una tobera con el fin de producir una cinta plana el prensado y enfriamiento tan solo de los bordes de dicha cinta cerca de la tobera la sustentación de la restante parte plástica caliente de dicha cinta fuera de contacto de todo cuerpo sólido hasta que se ha endurecido mediante sujección de sus bordes enfriados y mediante la sujección y tracción de la parte completamente endurecida de dicha cinta.
