Abstract
In the manufacture of packing containers of the non-returnable type for, e.g., milk, the forming and closing of the ridgelike top of the filled packing container represents the final phase in the manufacture. The top is provided with sealing panels which are intended jointly to form a top fin on the closed packing container. The present invention relates to an arrangement for the processing of a packing container by compressing and sealing the top fin of the container. The arrangement includes two processing jaws which are movably suspended in spring elements and are movable symmetrically between an active position wherein the jaws contact the sealing fin and an inactive position wherein the jaws are spaced from the sealing fin.
