METHOD AND DEVICE FOR CORRECTING SHAPE OF FILM OR THE LIKE, DEVICE FOR MOLDING FILM EQUIPPED WITH THE DEVICE, AND REWINDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for correcting the shape of film or the like by which the number of rejects in terms of shape is reduced and the quality is upgraded and a correcting device as well as a device for molding the film quipped with the correcting device, and a rewinding device. SOLUTION: A layered film 19 formed of two or more layers or the like is continuously heated in a shape adjusting section 15, preferably at a heating temperature above the second highest softening temperature level of the constituent layers and thereafter, is cooled down to the softening temperature level or lower of all the constituent layers. Thus the shape of the film 19 or the like is corrected.
