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.

Abstract: A roller conveyor supports a bale at a cutting and removing station. Side compactors and a top compactor compress the bale slightly for positioning it. The bale is pushed against a wire cutting channel in which a blade having a surface that protrudes into and forms a groove in the bottom surface of the bale is passed diagonally across the bale, with the wires springing into a recess in the blade. The blade continues to move, pulling the wire against the back wall of the recess until the wire exceeds its tensile strength and breaks. The bale is then lifted on pins so that a wire pulling blade can be moved also diagonally across the top of the bale. The pulling blade also has a forwardly inclined surface that pushes the bale down while allowing the wires to be captured in a recess in the blade. The blade is moved across the bale, capturing all of the wires and removing them from the bale. Another embodiment uses a turner to rotate the bale to cut and remove wires from adjacent sides of the bale.

Abstract: The invention involves a method of wrapping a roll wherein a sleeve wrap having a width substantially equal to the width of the paper roll is wraped around the cylindrical portion of the roll. A head of the same size as the end of the roll is coupled to each end of the roll. A stretch wrap is then wrapped around the ends of the roll so that approximately one-half of the stretch wrap covers a portion of the end of the roll and the other one-half lies in the same plane as the head. An end band may also be wrapped over the stretch wrap at each end of the roll. The invention also involves an apparatus that includes a trim slitter for trimming the sleeve wrap to the same size as the width of the roll.

Abstract: The invention provides an apparatus and method of inserting a lightweight, oversized, inside head to the end of a partially wrapped roll. An inside head is attached to multiple articulated arms extending from a spider assembly. The spider is moved toward the end of the roll until the articulated arms engage the end of the roll. The spider assembly opens the articulated arms radially outwardly until adjacent a wrapper tube extension. A heating clamp then welds the outer edge of the inside head to the wrapper tube extension.
