  • Method for shrink film wrapping employing two webs which are sealed together
    Patent number: 5766280
    Abstract: The disclosure relates to a method of shrink film wrapping one or more objects (12) in one or more rows. The objects are caused to be surrounded by two film webs (1, 4), which are sealed together by means of a sealing jaw (14). The objects (12) are moved in towards the two film webs (1, 4) by means of a pusher which, on its completion of the infeed movement stroke, stretches the two film webs (1, 4) in that the film webs are fixedly retained by each one of a hose brake (7, 8). When the sealing jaw (14) executes its downward stroke for completely shrouding the films (1, 4) around the objects (12), the sealing jaw (14) finally stretches the upper film (1). The film (1, 4) projecting outside the objects (12) is shrunk by means of hot air nozzles directed towards the objects (12).
