Abstract: An apparatus and method is provided for simultaneously perforating and cutting a lithe sheet material having multiple layers containing at least an upper and lower layer, comprising a knife die having a cutting edge, wherein the cutting edge is contained in the same plane, and an anvil die located opposite the knife die, wherein the surface of the anvil die contains a pattern of cavities which corresponds to the locations where primarily only the upper layer of the material is cut completely through and protrusions of the anvil primarily correspond to the locations where the entire thickness of the material is cut along the same line as the cut through the upper layer.

Abstract: An apparatus and method for preparing wound rolls from a web of material is disclosed having a feeding roller which feeds a web of material into contact with a core having a central axis. A plurality of tuckers tuck the web of material about the core, then the web is wound about the core having an enlarged diameter. A sealant is applied to the wound rolls, while the rolls are on the core, so as to maintain the rolls in a tightly wound manner. The core is attached to two support members, at least one support member being movable between a position attached to the core and a position dislocated from the core. After the sealant has been applied, at least one support member moves to the dislocated position such that wound rolls may be removed from the core by a movable extractor. The extractor forces the wound and sealed rolls off the core, which has a reduced diameter, and into a bin.

Abstract: An apparatus and method for preparing individual wound rolls from a slitted web of material provides for a driver roller which continuously feeds the web of material into the apparatus, an idler roller disposed such that the web of material is fed about the driver roller and into contact with the idler roller; a core disposed such that the web of material passes between and into contact with the driver roller and the core, and the idler roller and the core; a tucking apparatus for tucking the web of material about said core; and a reciprocating roller for driving the core to initiate and continue winding of slitted web of material about the core.
