Abstract
PURPOSE: To apply heat evenly be providing gaps made of fine jogs on the surface of a heater roller so that air can escape through the gaps.
CONSTITUTION: Gaps 4 made of jogs or grooves are formed on the surface of a heater roller 3 so that air can escape through the gaps. A thermoplastic film 1 goes around the heater roller 3 where the film is heated up, and it is formed by a vacuum forming roller 5. In this process, the film 1 is brought into tight contact with the roller 3 because the air escaping gaps are provided on the surface of the heater roller 3; thus uniformly heating up the film 1.
