Zusammenfassung:	An apparatus for producing expanded metal from a metal foil includes a cutting tool which provides the advancing metal foil with intermittent cuts in conveying direction. Arranged at a downstream portion, the apparatus comprises a stretching unit which includes a pair of toothed bottom belts and a pair of toothed top belts which seize and clamp the metal foil along its edges and stretch the latter in a direction transverse to the conveying direction, if necessary, by cooperating with a nose-like ramp interposed between the pair of bottom belts and the pair of top belts.
