Abstract
An apparatus for removing slip sheets from printing plates has two concentric cylinders that are mutually rotatable about a common axis. Suction exerted via two elongated slots separates a deformable sheet from a relatively rigid object to which it is adhered. The deformable sheet is drawn into a recess presented by the two aligned slots. The concentric cylinders are then rotated to grip the deformable sheet between opposing edges of the slots.
