ABSTRACT:
Apparatus for unwinding synthetic resin film from large mill rolls of such film, and concurrently winding the film in a product roll for purposes of marketing, after transversely perforating the film at spaced intervals along its length to form a series of detachably interconnected sheets of film. The apparatus includes means for automatically feeding mill rolls to the unwinding mechanism of the apparatus, means for optionally automatically or manually braking the rotary motion of a rotating, unwinding mill roll with a braking force of a magnitude correlated to the constantly changing diametric size of the unwinding mill roll, and means for automatically counting, in a precise fashion, the number of sheets of the film formed in the wound product roll defined by pairs of adjacent perforations therein. The apparatus further includes novel scoring and perforating means for transversely perforating the film as it moves between the unwinding mill roll and the wound product roll, and means for concurrently and independently unwinding film from a pair of mill rolls.
