A packaging machine, said packaging machine comprising:
- a sealing station;
- a frame disposed at one of a supply side or a discharge side of said sealing station, said frame disposed at least partially above one of a first transport belt of a supply device on said supply side, or a second transport belt of a discharge device on said discharge side, said frame having a shaft mounted for rotation thereon and two rolls are disposed on said shaft;
- a protective hood operably connected to said frame, said protective hood including one or more guides;
- wherein said rolls are positioned on said shaft to engage the one or more guides of said protective hood, and the one or more guides cooperate with the rolls in such a manner that the protective hood is liftable and tiltable around the shaft and a movement of the protective hood between a closed position and an opened position comprises at least a rearwardly directed linear movement;
- and
- wherein said protective hood is disposed above one of said first transport belt or said second transport belt when the protective hood is in the closed position.
