A piling device (11) forms a pile (15) of sheets (12). For pile change, the finished pile (15) is separated from sheets of the subsequent pile by means of a separating finger (22). After the main stop (17) at the front pile edge has been swung away, the pile is horizontally removed by means of a pile removal device (30) having grippers (31, 32). While this is happening, a carrier element (47) in the form of a horizontally located rack follows the rear pile edge (78) in the region of the pile upper surface (101) so that the separated newly forming pile is immediately taken over onto the carrier element (47). A holding device (77) supports the rear edge of the new pile and holds it firm. The new pile is then transferred onto a piling table (14) by lowering the carrier element (47). A second carrier element (48) works in paternoster fashion with the first and, for the next pile, carries out the same functions as the first set.

An apparatus for successively stacking and removing piles of sheets conveyed to the apparatus, comprising: two alternatively operable carrier elements for the piles; means operable at the front edge of the pile, relative to the transport direction, for separating finished piles from subsequently conveyed sheets; means for removing finished piles; first means for alternatively driving each said carrier element along the sheet transport direction, the leading edge of each said carrier element moving near the trailing edge of a finished pile being removed and substantially in a plane defined by the top surface of the finished pile; and, second means for alternatively driving each said carrier element along the sheet piling direction, substantially perpendicular to the sheet transport direction, whereby the carrier elements alternatively support newly forming piles until each completed pile is engaged by the pile removal means.
