Abstract
According to a film removing device, a film-coated resin molded material having a film coated on one surface of a matrix resin is flattened by a flattening roll in a heating chamber. Further, the film-coated resin molded material is fed between a peeling roll and a feeding roll of roll type rolling means for rolling and stretching. The velocity of a peeling surface of the peeling roll is made relatively higher than the velocity of a feeding surface of the feeding roll, whereby a difference in elongation between the matrix resin and the film, and a shearing force are produced to peel the film. An applicator type supply device supplies a liquid as frictional force reducing means (e.g. water) to the peeling surface and the feeding surface. Thus, a frictional force is reduced, and stretching accompanying rolling fully works. Consequently, the film becomes easy to fracture and peel, and its peeling can be performed effectively.
