Abstract

PURPOSE: To make a location of the necking-in of an elongating film constant at all times and enable the uniform elongation of the film at high magnification by a mechanism wherein a heating apparatus is provided which consists of a forced cooling portion and a high temperature portion.
CONSTITUTION: A heating apparatus 10 is formed by a forced cooling portion 11 and a high temperature portion 12, and a joining location of the both portions 11, 12 is set at a position (a region where frictional resistance by an upper curved surface of the heating apparatus 10 to a film decreases and an adhering property is excellent) suitable for the necking-in of the film (where notations 15, 16 are delivery rolls and a notation 17 is a receiving roll). When the heating apparatus 10 is formed in such a manner, a location of the necking-in of the film is made constant at all times regardless of elongation at low magnification or elongation at high magnification, and the film can uniformly be elongated continually.
