PCT No. PCT/EP85/00613 Sec. 371 Date Jul. 11, 1986 Sec. 102(e) Date Jul. 11, 1986 PCT Filed Nov. 12, 1985 PCT Pub. No. WO86/03027 PCT Pub. Date May 22, 1986.The invention relates to a device for the cyclic rearrangement of a pile of rectangular or square sheets, especially a pile of photographic prints, having 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, and having means that, on movement of the frame parts backwards and forwards, remove an individual sheet from one end of the pile and add it to the other end of the pile again, these means comprising: (a) a separating means (20/266) for separating the individual sheet (188) from the pile, (b) a feeding means (460) for feeding sheets to the separating means, (c) retaining means (460/20) for holding the individual sheet in the first frame part and the remainder of the pile in the other frame part, and (d) a guide means (386) for guiding the separated individual sheet for the purpose of returning it to the other end of the remainder of the pile, wherein the feeding means and the retaining means for holding the individual sheet are formed by a transporter (460) engaging the rear edge (seen in the feeding direction) of the sheet to be separated and wherein a pressure arrangement (476) is provided on the side of the pile remote from the transporter, wherein the device is designed for piles having different numbers of sheets, the pressure arrangement holds the sheet being separated in engagement with the transporter until the latter enters the separating means, and wherein the guide means comprise means (490) which, controlled by the movement of the frame parts, permit the introduction of the individual sheet between the pressure arrangement and the pile. |
