To provide for transfer of folded products, such as folded printed sheets received from a printing machine, between storage bins and a conveyor transport system, transport sheets which, at least in part, are magnetizable, are retained in the storage bins; a transfer element (9) in form of an endless elongated belt or the like has electromagnets secured thereto which are selectively energized to pick up the transfer sheets. The transfer element or belt is guided in a path past a delivery end (7') of a storage holder, then into the path of the transport system (2, 3) for transfer of folded products (1) from or to the sheets, and return of the sheets to a receiving end of the storage bin, at which point the magnets are deenergized to release the sheets into the bin, and can continue to travel--while deenergized--in an endless path for subsequent pick-up of sheets.

Folded products transport apparatus

To provide for threading of paper webs to a folding apparatus (140), a plurality of paper webs (1-8; 77-84) are fed from respectively opposite sides to a plurality of deflection rollers directing the paper webs in a vertical combining plane (9). The deflection rollers are positioned in vertically staggered arrangement. The paper webs are positively fed by transport rollers (26-29; 53-56) or transport belts (110-113; 128-130), located on respective carrier plates (18, 19; 93, 94) which are movable towards or away from the combining plane and on which the transport rollers or belts are located, staggered, between the deflection rollers on the same side and so as to engage the deflection rollers on the other side of the combining plane, to provide for positive drive of paper webs and feeding to the folding apparatus (140) during threading, or upon tearing of a web, but permitting withdrawal laterally upon full-speed operation of the paper handling apparatus, for example the folder. Additional transport belts (69, 70; 138, 139), also movable on carriers towards and away from the combining plane, can be provided to transport the combined superposed webs, likewise movable out of engagement with respect to each other, that is, away from the combining plane, after threading has been completed.
