A material pallet moves reciprocally between a loading/unloading station ST-0, at one side of a plate processing machine 1 e.g. a turret punch, and one of two stations ST-1, ST-2 flanking station ST-0. With the material pallet at station ST-0 a workpiece W is separated from those carried by the pallet and is loaded into the machine by a transfer device 43. The material pallet is transferred from station ST-0 to station ST-1 and a product pallet is transferred from station ST-2 to ST-0 during processing of workpiece W. The finished product is then transferred to the product pallet at station ST.0 by the transfer device 43. The product pallet is transferred to station ST-2 and the material pallet is transferred to station ST-0. Pallet storage shelves (29, Fig. 3) are located in ST-0 above the transfer device 43 and an elevator (77, Fig. 3) including means for feeding pallets laterally is movable vertically in ST-1 to transfer pallets between the shelves and the transfer device. A two-station arrangement (Fig. 4) includes a transfer device incorporating a device (157, Fig. 6) for locating a workpiece at a home-position in the processing machine. An alternative transfer device includes a home-positioning device (165, Fig. 12), movable in X- and Y-axis directions and pivotable in the horizontal plane, and a workpiece clamp (163, Fig. 11) pivotable so that it can clamp an inclined workpiece edge without bending it. <IMAGE>
