Abstract
Apparatus for feeding dielectric receptor sheets and/or sheet-like carriers for receptor sheets to the ionography imaging chamber of a radiographic system from a nearly upright stack of overlapping sheets has a set of suction heads which are mounted on a first lever pivotally mounted on a second lever. The first lever is repeatedly pivoted relative to the second lever to thereby move the suction heads, which attract a portion of the outermost sheet of the stack below the upper edge face of such sheet, along an arcuate path to thereby flex the upper part of the outermost sheet away from the neighboring sheet. The second lever is thereupon pivoted to complete the separation of the outermost sheet from the neighboring sheet and to introduce the upper edge face of the separated outermost sheet into the nip of two advancing rolls which transport the sheet toward or into the interelectrode gap of the imaging chamber. A stripping device is adjustably mounted in the path of movement of outermost sheets with the suction heads relative to the second lever to flex such sheets between the suction heads and the respective upper edge faces whereby the outermost sheets are even more likely to become separated from the neighboring sheets. A pivotable lever is provided to maintain the stripping device in such position that the latter is located at a fixed distance from the paths of upper edge faces of successive outermost sheets, irrespective of changes in the thickness of the stack.
