  • Patent number: 5021039
    Abstract: An apparatus for manufacturing air-cushion dispatch packages, the apparatus comprising an unwinding mechanism for paper webs and air-cushion foil webs. The apparatus introduces air-cushion foil webs between the paper webs and seals each paper web to a foil web over a large area. Transverse and longitudinal sealers seal the edges of the packages. After each sealing operation, the webs are subsequently cooled. Pulling rollers press the paper webs in the edge regions of the packages and advance the webs. Cutters cut the dispatch packages to the desired format. Web controllers correct deviation of the paper webs. A cycle controller is included.
