ABSTRACT:
Method and apparatus for cutting a wrapper on a cylindrical roll in which a blade has a pointed tip joined to an inclined edge extending outwardly and an opposite smooth surface, the blade being moved under the outer wrap of the wrapper but outward of the material of the roll and continuing to be moved along a predetermined path along the length of the roll, with the inclined edge cutting the outer wrapper. The blade is positioned perpendicular to the roll and circumferentially from the outer end of the wrapper. In a preferred embodiment a longitudinal bubble is formed in the outer wrap of the wrapper and the blade tears through the crown of this bubble. Also in the preferred embodiment, a gathering device is provided for removing and flattening the cut wrapper.
