An apparatus for closing packages made from a heat-sealable material has sealing jaws, which are subdivided by a recess or by slits into two zones. What is essential is that the two zones are eastically joined together by means of a connecting web, so that when a transverse seam is sealed, it is possible to compensate for a different number of layers of packaging material along the transverse seam. The apparatus according to the invention is relatively simple in structure and makes high sealing qualities attainable. |
