Abstract (en)
Method and apparatus for cutting a wrapper on a cylindrical roll (R) in which a blade (36) 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. A track having gauge rails (34) resting on the roll (R) spaces the tip of the blade (36) a predetermined distance outwardly from the roll. A gathering device is provided for removing and flattening the cut wrapper. <IMAGE> <IMAGE>
