A vacuum stripping system for stripping copy sheets from the initial imaginf surface of a copying apparatus after the images have been transferred to the copy sheets. A pivotable, highly apertured stripping head is normally closely spaced from the imaging surface, normally pivotably extending from a vacuum manifol having an apertured lower surface providing a fixed copy sheet guide surface. The air flow through the higly apertured stripping head captures the lead edge area of the copy sheet. Preferably more than half of the area of the stripper head is so apertured. The coverage of the vacuum apertures in the stripping head by the captired copy sheet automatically causes the stripping head to self-lift away from the imaging surface solely by vacuum force into alignment with the lower surface of the vacuum manifold, and shofts the stripping point of the remainder of the copy sheet upstream along then imaging surface in the positively controlled manner. The stripper head is preferrably pivotably mounted adjacent its upstream edge to the vacuum manifold. This stripping system allows maximixation of the vacuum stripping air flow and close spacing for positive stripping of a strongly adhering copy sheet, yet provides an improved paper path for the copy sheet after stripping has been initiated and non-contact protection for delicate imaging surfaces.
