  • the gears in the input area and / or in the output area may be connected to each other, preferably by a rigid shaft.
  • Each transport means has a plurality of clamping means which grip the lower film web 8 in the inlet region 19 in a clamping manner and transmit the movement of the transport means to the lower film web 8. In the outlet region of the packaging machine, the clamping connection between the transport and the lower film web 8 is released again. Downstream of the inlet region 19, a heating means is provided which heats the film web 8, especially when it is stationary.
  • thermoforming station 2 which here has an upper tool 3 and a lower tool 4, which has the shape of the packaging tray to be produced, the packaging trays 6 are formed in the warmed film web 8.
