摘要:
An apparatus and method for spirally winding a foil roll with a wound stiffener core (12) in which a stiffener sheet (16) 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 (20) of a foil web. The stiffener sheet (16) 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 (12) is formed allowing a desired length of foil web to be spirally wound around the core (12) without damage to the web. The apparatus is configured to receive a continuous supply of foil and stiffener web material, cut each to predetermined lengths, and sequentially form wound core foil rolls (10) at an economically high rate.
