ABSTRACT A device for the cyclic rearrangement of a pile of rectangular or square sheets, especially a pile of photographic prints, has a first (12) and a second (14) frame part which may be moved relative to one another and parallel to the main plane of the pile. On movement of the frame parts backwards and for- wards, an individual sheet is removed from one end of the pile and added to the other end of the pile. A separating means (20/266) separates the individual sheet (188) from the pile, and a feeding means (460) feeds sheets to the separating means. Retaining means (460/20) holds the individual sheet in the first frame part and the remainder of the pile in the other frame part, and a guide means for guides the separated individual sheet for the purpose of returning it to the other end of the remainder of the pile. The feeding means and the retaining means are formed by a transporter (460) engaging the rear edge (seen in the feeding direction) of the sheet to be separated and a pressure arrangement (476) is provided on the side of the pile remote from the transporter. The pressure arrangement holds the sheet being separated in engagement with the transporter until the latter enters the separating means, and the guide means is controlled by the movement of the frame parts and permits the introduction of the individual sheet between the pressure arrangement and the pile.
