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 drive 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.

L'invention propose un dispositif d'estampage de couvercles de flacons ou similaires, qui présente un pont (10) porté sur un bâti, qui porte des outils (1) de presse d'estampage actionnés en continu et de manière répétée à la verticale, le pont présentant un dispositif (30) de transport longitudinal qui transporte pas à pas des plaques de tôle (11, 12) lorsque les outils (1) sont ouverts et un dispositif (20, 40) de transport transversal qui décale latéralement de manière limitée ces plaques de tôle (11, 12) qui se déplacent ou sont déplacées longitudinalement. Sur le côté d'amenée et le côté d'évacuation, sensiblement symétriquement par rapport aux outils (1), des dispositifs respectifs (20, 40) de transport transversal aptes à être commandés séparément sont disposés en position stationnaire en amont et en aval des outils et à proximité d'eux, et portent chacun une paire de cylindres d'entraînement (31, 32; 51, 52) qui porte le dispositif (30, 50) de transport longitudinal, qui transporte de manière contrôlée et serrée les plaques de tôle (11, 12) ou les libère de manière contrôlée. L'invention propose également un procédé d'utilisation du dispositif décrit.
