PURPOSE:To provide a method for simultaneously manufacturing a plurality of stretched films by preventing adherence of films when a plurality of thermoplastic resin films are superposed and at least laterally stretched. CONSTITUTION:In a method for simultaneously manufacturing thermoplastic resin films of a plurality (n) of stretched films having the steps of superposing a plurality (n) of films 12, 13 made of thermoplastic resin, at least laterally stretching it and then isolating the superposed films 12, 13 said method comprises the steps of continuously longitudinally folding ends of 1 to (n-1) films 12, 13, superposing another films 12, 13 of the side of folded ends, and laterally stretching them. |
