Abstract

A sealing station for a packaging machine, the sealing station may be a tray sealer. The sealing station includes an upper die with a sealing plate and a lower die with a tray holder for receiving at least one packaging tray to be sealed. A cutting blade is arranged within the sealing station, and cuts a lid for closing the packaging tray out of a top film. The cutting blade has an endless cutting edge for cutting out the lid along its contour. The cutting blade includes a first and a second blade section, for cutting out a first and second section of the contour of the lid respectively. The second blade section may produce a tear-off corner in the lid projecting beyond the edge region. The sealing station may include a first clamping jaw on the sealing plate, and a second clamping jaw on the tray holder.
