  • Foil roll with wound stiffening core, apparatus for winding the roll and method
    Patent number: 8540181
    Abstract: A foil roll having a wound stiffener core formed from an initially flat sheet of stiffener material fed into a spiral roll winder simultaneously with a feed end of a foil web. An apparatus and method for spirally winding a foil roll with a wound stiffener core in which a stiffener sheet is fed into a roll winder in adjacent outward contact with a foil web and a leading edge of the stiffener slightly ahead of a feed end of a foil web. The stiffener sheet is outwardly disposed from the foil web and in adjacent contact with the roll starter guides to prevent contact between guides and the foil web during initial core formation. Roll starter guides are moved from contact with the outer periphery of the roll once the initial core is formed allowing a desired length of foil web to be spirally wound around the core without damage to the web.
