Abstract

Un dispositivo para fabricar una hoja a base de materiales sintéticos termoplásticos, caracterizado porque está prevista una calandra para la elaboración de la hoja, detrás de la que está montado directamente por lo menos un cilindro de fusión, si bien con preferencia dos o tres cilindros de fusión, y porque están previstos asimismo rodillos de retirada, que retiran la hoja a velocidad elevada del cilindro o los cilindros de fusión, pudiendo servir como rodillo de retirada en cada caso otro cilindro de fusión montado detrás.
