Abstract
Method and apparatus for peeling a carrier web having a protective layer from a keeper sheet of image-bearing medium. The carrier web and the protective layer are peeled about a peel member as the keeper sheet moves over and is deformed by a constraining roller located at or downstream of the peel member putting the protective layer in tension. Preferably, at least one of the peel member or the constraining roller has a compliant material covering to facilitate separation of unused portions of the protective layer from edges of the keeper.
