Abstract
Procedimiento y aparato para fabricar cinta ondulada de plástico, caracterizado porque después de calentada una cinta lisa de plástico hasta la temperatura de reblandecimiento se la hace pasar entre dos bandas de rodillos que la dan forma ondulándola, efectuándose a continuación un enfriamiento de la citada cinta de plástico ya conformada antes de abandonar las bandas de rodillos, por lo que al dejar éstas la cinta ondulada queda suficientemente rígida para conservar la ondulación.
