  • Patent number: 6662533
    Abstract: The present invention relates to a method of shrink film wrapping of one or more objects (15). The method employs two film webs, a first (1) and a second (2). The first film web carries a pre-printed decorative artwork with regularly recurring register maintenance markings. The second film web (2) is blank and carries no register maintenance markings. The two film webs (1, 2) are joined or fused together when the objects (15) are moved in by means of a pusher (16) towards the film webs (1, 2), in one or more rows. A sealing device (18, 19), consisting of an upper (18) and a lower (19) sealing jaw, stretches the film webs (1, 2) around the objects (15) and once seals the film webs (1, 2). During the downward movement of the upper sealing jaw (18), the first film web (1) is held fast by a brake (8). The first film web (1) is held in register in that the first film web (1), during the sealing, is advanced by means of a drive roller (6) for the formation of a loosely hanging loop (21).
