Zusammenfassung:	A method and apparatus for forming shaped articles such as heat exchanger plates and fuel cell plates from a strip of material. The apparatus includes a feed mechanism for feeding the strip; one or more forming devices which form peripheral features and/or discontinuities in the strip; and an alignment device which maintains constant spacing between the discontinuities and thereby avoids accumulation of incremental feeding errors. Preferably, the strip is re-aligned once for eac h plate produced. The alignment device comprises a pilot pin and a pilot hole punch for forming index holes in the strip, and can be integral with or separate from the forming devices. One preferred apparatus utilizes a forming device comprising a plurality of punches mounted on a reciprocating frame or gantry structure.
