A device for producing container blanks (2) from a material web (3), comprising a rotary tool holder (4) supporting a plurality of tools (5) which are adapted to engage the material web (3) and to be moved together with said material web (3) along a working path (WP) under maintained engagement to join opposite wall portions of the material web (3) along connecting portions (11) outlining said container blanks. Each tool (5) comprises a base element (6) which is fixedly mounted on the tool holder (4) and an engaging element (7) which is pivotable about an axis relative to the base element (6) for operation of the tool (5) between a closed position and an open position, the tool (5) being movable to said closed position to provide said engagement with the material web (3). The engaging element (6) has a profile structure (33) supported by a carrier structure (34) and facing the base element (6) in the closed position of the tool (5), wherein springs (38) being arranged between the profile structure (33) and the carrier structure (34) such that the springs (38), when the tool (5) has been moved to its closed position, are compressed to a predetermined extent. |
