Abstract
Methods and apparatus for peeling a laminate containing image media wherein the leading edge portion of the laminate is struck by beater blades to initially separate the leading edge portion of one layer from the laminate. The separated leading edge portion is then transported into a nip defined by a peel surface and a lower peel roll after which the leading edge portion is bent about the peel surface by a folder driven by a linkage mechanism. While the leading edge portion of the laminate is bent, one layer is held by a vacuum device while the remainder of the laminate returns to its path of travel under its own resiliency. The separated layer is then peeled from the laminate by take-away rolls while guided by the peel surface. The remainder of the laminate is guided by a deflector roll to move along the path at a predetermined angle while the layer is being peeled. In one method, the layer is peeled at an angle to the longitudinal direction of the laminate. This is effected by orienting the peel surface and the lower peel roll with their axes extending at an angle to the path of travel of the laminate. Further, a method includes having the layer peeled at an angle other than the …
