Abstract
A stretch-forming press for stamping continuously fed sheet metal includes a ram, a base member, and a feed mechanism configured to advance a strip of sheet metal through the stretch-forming press. A forming station has a die configured to form a desired pattern in the strip of sheet metal. A leveling station has a pair of opposed jaws slidably received in corresponding recesses of the stretch-forming press, with the jaws oriented at an angle with respect to a direction of travel for the strip of sheet metal as it passes through the leveling station.
