发明名称 Film cutter
摘要 A cutting apparatus cuts shrink wrap film residing in a roll. The apparatus includes a first roller pair receiving the film from the roll and carrying the film away from the roll; and without the need for a second roller pair to receive the cut sheet of film. Film snap-back is prevented by cutting the film between a shear deck with teeth and a rotating blade with teeth intermeshing with the teeth of the shear deck. A method for cutting a sheet of shrink wrap film, includes: feeding the film into a first roller pair; and cutting the film between the first roller pair and the second roller pair using a rotating knife with a number of teeth intermeshing with a shear bar with teeth.
