Abstract
An apparatus and method for removing sheet or web material from a roll employs an at least partially hollow cutting tube that rotates against a cull roll. The cutting tube has a slot along some of the length of the tube and carries a blade that is extendable from the slot. As the slot positions against the cull roll, the blade is extended and translated along the length of the slot to cut the material away from the roll.

A method of removing material from a full or partial parent roll, the method comprising:
- providing a cutting tube, the tube having an at least partially hollow area, the cutting tube having an outside cylindrical surface with having an opening along the length of the cutting tube, the cutting tube rotatable along its axis;
- the cutting tube having a blade, the blade located within the tube and extendable from the opening;
- wherein the blade is mechanized for translation longitudinally along the length of the opening;
- placing a full or partial parent roll in physical contact with the cutting tube;
- and
- rotating the full or partial parent roll and intermittently extending the blade from the cutting tube and cutting material from the cull roll.
