ABSTRACT:
The subject invention relates to a device for cutting and stripping the backing film from a sheet of MYLAR film. There are two embodiments disclosed. The first embodiment relates to the packaging of MYLAR film in a box with disposable end plates attached to the roll core. A pair of stripping rollers are rotatably attached to the film core to permit rotation of the stripping rollers as the film is pulled from the storage roller. With the backing film inserted between the sripping rollers the backing film is automatically stripped from the MYLAR film as it is pulled from the box. A cutter and measuring mechanism including a horizontal and vertical cutter with automatic retract for the horizontal cutter is also provided. The second embodiment relates to a device used by professional MYLAR installers. The professional unit includes the same cutting and measuring mechanism, however, a further roller mechanism is provided to permit the unused portion of MYLAR with its backing film attached to be rolled thereon, while the portion being used is automatically stripped of its backing film.
