Abstract
A method and apparatus for removing a liner from a formed metal closure by at least partially everting the closure with an advancing punch adapted to temporarily couple the everted closure. By everting the closure, the liner becomes accessible to be retained within the closure support and is separated from the closure when the punch is retracted. A stripper is provided adjacent the punch to separate the everted metal portion of the closure from the punch.
