Bei einer kombinierten Form-/Stanzstation (8) oder einer Stanzstation zum Ausstanzen von tiefgezogenen Behältern, die aus einer erwärmten thermoplastischen Kunststoffolie (4) hergestellt sind, wird die Übertragung von Stanzschlägen von der Ober-/Unterbrücke (14/12) der Form-/Stanzstation (8) auf an diesen angeordnete Einrichtungen vermindert. Dies wird erreicht durch den Zwischenbau von Dämpfungspaketen (30), die aus mehreren starren Platten (31) aus Metall oder Kunststoff bestehen. A plastic container stamping or combined molding and stamping apparatus has damping disc stacks (30) between its transoms (14) and fittings (32) such as drives, ejectors and sensors. An apparatus for stamping or combined molding and stamping of containers, formed by deep drawing of hot thermoplastic foil, has an intermittent conveyor and a stamping or combined molding/stamping station with upper and lower transoms provided with devices such as drives, ejectors and sensors. Damping disc stacks (30) are provided between the transoms (14) and the devices (32).
