Abstract

PURPOSE: To prepare a rough surface transferred film integrated with a reinforcing film by casting a melted resin liquid between a press roll and a rough surface roll equipped with cooling means while the reinforcing is interpored therebetween.
CONSTITUTION: The film extruded from a T die 13 of an extruder is integrated with the reinforcing film 14 between the press roll 11 and the rough surfaced roll 10. The film 15 integrated with the reinforcing film 14 is sent to the roll 10 so as to be contacted with about 1/3W1/2 of the periphery thereof and released therefrom. The rough surfaced roll 10 has a rough surface 17 applied over a total periphery thereof and a jacket is formed in an interior thereof and said roll 10 is cooled by recirculating water thereinto.
