1. A thermoforming packaging machine comprising:
a transverse cutting station, wherein the transverse cutting station has a punching device including a punching tool comprising a punch and a die for separating one or more film sections from a lower film and/or an upper film, wherein the punching device comprises a chamber configured to at least temporarily receive the one or more film sections, and a suction device to convey the one or more film sections out of the transverse cutting station, wherein the punching device comprises a hood that forms the chamber with the die, the chamber comprises at least first and second openings, the first opening is formed by the die, and the first opening is configured to receive the punch during a cutting process to separate the one or more film sections from the lower film and/or the upper film; and
a compressed gas source fluidically connected to the suction device.
 
13. A method for operating a thermoforming packaging machine comprising a transverse cutting station, wherein the transverse cutting station comprises a punching device for cutting out one or more film sections from a lower film and/or an upper film by a punching tool including a punch and a die, the method comprising:
cutting out at least one film section from the lower film and/or the upper film by the punching tool, wherein during the cutting out, the punch enters an opening formed by the die;
at least temporarily receiving the at least one film section in a chamber of the punching device, wherein the opening formed by the die forms a first opening of the chamber; and
generating a volume flow by a compressed gas source in order to convey the at least one film section out of the chamber of the transverse cutting station;
wherein the first opening of the chamber is released by guiding the punch out of the die.
 
21. A method for operating a thermoforming packaging machine comprising a transverse cutting station, wherein the transverse cutting station comprises a punching device for cutting out one or more film sections from a lower film and/or an upper film by a punching tool including a punch and a die, the method comprising:
cutting out at least one film section from the lower film and/or the upper film by the punching tool;
at least temporarily receiving the at least one film section in a chamber of the punching device; and
generating a volume flow by a compressed gas source in order to convey the at least one film section out of the chamber of the transverse cutting station, wherein the generation of the volume flow is interrupted at least for a duration of a punching operation.
