A device for feeding a metal strip to a numerically controlled tool, blanking press or the like is disclosed comprising a pair of rollers between which the strip is nipped and fed forward by applying rotational drive to the rollers. Compressed air, acting upon the upper surface of one of the rollers urges the rollers together, creating the nipping pressure. A stepping electric motor provides the rotational drive which causes the feed movement of the strip.
