<p>A method for thermoforming a belt-shaped film excelling in strength by increasing the fluidity of the belt-shaped film while being formed. A heated surface (7a) of A1 X B1 in square measure, about 1.2 times greater in each dimension than the area A2 X B2 of an opening of a processing section, is heated to a temperature which permits forming with paired heating blocks (1b, 2b) from above and below a belt-shaped film (7), and the heated surface (7a) is thermoformed with a molding punch (10) and a molding die (11).</p> |
