ABSTRACT:
To permit introduction of adjacently located sheet elements (20, 22), for example folded sheets (24), received from a folding flap cylinder (2), with the fold line or spine leading and with the sheet elements spread apart, a guide belt (13) has laterally projecting fingers (12) which engage between the sheet elements (20, 22), the guide belt being positioned adjacent to and operating at essentially the same speed as a pair of transport belts (25, 26) between which the sheet elements are being transported. The fingers are inserted between the sheet elements as a sheet (24) is folded or two individual sheet elements are gripped by a folding flap or gripper cylinder (2), and remain between the sheet elements upon transport by the transport belt system. At a delivery region, adjacent a storage unit, the guide belt is deflected over a roller, thereby twisting the fingers and spreading the sheet elements apart adjacent their trailing ends, by guiding the guide belt in a path different from the transport belt system. Preferably, the spread-apart sheet elements are transferred to an accordion or zig-zag pocket structure, for example made of elastic sheet elements, which, to receive the spread-apart sheet elements, has the accordion pockets spread, for example for a worm (50).
