An apparatus for packing goods between opposed webs (2, 9) comprises a drawing station (3, 5, 6) for forming wells (7) in a lower web (2), and a heat-sealing station for heat-sealing an upper web (9) around the edges of the wells (7) in the lower web (2) after the goods have been introduced in the wells (7). In the heat-sealing station, vertically displaceable welding elements (10, 13) for longitudinal and transverse seams are arranged below the webs (2, 9). Longitudinal welding elements (10) are arranged over the web width in accordance with the particular number of longitudinal seams required and the length of said longitudinal welding elements is equal to or greater than the length of the individual packs to be formed. The transverse welding elements (13) are situated downstream of the longitudinal welding elements and are displaceable in the longitudinal direction of web advance. The welding elements, which are interchangeable with one another, are constructed as plug-in elements. <IMAGE> |
