ABSTRACT:
A piston-cylinder arrangement is provided for mounting and actuating the lower tool of an indexing packaging machine, which has an annular piston head that has a ratio of outer diameter to inner diameter that is less than two, and which drives a relatively oversized hollow piston rod having a protruding mounting portion that projects upwardly and outwardly from the main cylinder, to the upper end of which is mounted an upper mounting plate connected to the lower tool of a station of the packaging machine. The oversized piston rod or shaft ensures stable and tilt-free mounting of the lower tool that ensures the parallelism thereof with the upper stationary tool, while providing more than the necessary force for activating the lower tool.
