A device for cyclically rearranging a pile of rectangular or square sheets, particularly a pile of photographic prints, comprises a first and a second frame parts movable with respect to each other in parallel to the main plane of the pile. During the reciprocating motion of the frame parts, elements grab a sheet from one side of the pile and bring it to the other side of the pile. Said elements comprise: (a) a separator device to separate a sheet from the pile, (b) a feeding device to feed the sheets to the separator device, (c) holding devices to hold the individual sheet in the first frame part and the remainder of the pile in the other frame part, and (d) a guiding device to bring back the individual sheet to the other side of the remainder of the pile. A driver (22, 404, 420) which hooks the rear edge of the sheet to be separated in its feed direction is used as a feeding device, and at least one additional element (26/28, 32/80, 506/520, 300/306, 278, 32/288, 274) is used as holding device for the individual sheet. |
