Abstract
The invention describes an apparatus for stamping can lids or the like, having a bridge (10) supported on a frame and carrying stamping tools (1) actuated vertically in a continuously repeating manner, having a longitudinal conveying device (30) gradually transporting metal sheets (11, 12) under said tools (1) in each case with the latter opened, and having a transverse conveying device (20, 40) laterally displacing to a limited extent the metal sheet (11, 12) moving or moved longitudinally in each case, wherein a separately controllable transverse conveying device (20, 40) is arranged in a stationary position in each case on the feed and discharge side approximately symmetrically to the tools (1) close in front of and behind the latter, said transverse conveying device (20, 40) in each case carrying a driving roller pair (31, 32; 51, 52) as the longitudinal conveying device (30, 50), which delivers the metal sheet (11, 12) in a controlled clamping manner or releases it in a controlled manner.Furthermore, a method of using the apparatus described is presented.
