Device using seals to close off sheet packing for food material

摘要

At least one of the sealing devices has a heating facility (6), and the counter seal plate (5) is fixed to a pivot arm. The counter seal plate can therefore be pivoted between a closed and an open state and vice versa by drive from the pivot arm. The drive device comprises a cam plate from which a drive mechanism for the pivot arm is effective. The drive mechanism has at least one intermediate pivot arm with a contact pin driven by the cam plate.
