Abstract

PURPOSE:To enable a plastic film opened at its one side to be continuously folded back without any extra space, by folding back the one side opened plastic film, flat without any wrinkle, as in the process of a paper folding hand work of children. CONSTITUTION:In order to fold back an one side opened film 3, the film 3 having a long length is made to pass between film pay-off rolls 1, and then is led through a gap between flat plates 6, 7. When the forward end of the film 3 reaches the fold-back serving sides 8, 9 of the flat plates 6, 7, the upper side piece 3-2 of the one side opened film 3 is folded back along the fold-back serving side 8 of flat place 6 so that the inner and outer surfaces of the film 3 are reversed, and the lower side piece 3-1 of the film 3 is folded back along the fold-back serving side 9 of the flat plate 7 so that the inner and outer surfaces of the film 3 are reversed.
