  • Patent number: 4563857
    Abstract: A method for stretch film wrapping of goods aggregates (6) in a line operation including keeping the stretch film tensioned between a ready-wrapped goods aggregate and a stretch film store, and forming a new goods aggregate (6) by moving at least two articles towards each other and into contact with either side of the stretch film so that the stretch film is clamped between the articles (4) in the new goods aggregate. The stretch film can then be parted between the new goods aggregate and the ready-wrapped goods aggregate (6'), after which the new goods aggregate (6) is wrapped with stretch film with the aid of a conventional wrapping means. An apparatus for carrying out the method includes, apart from a conventional stretch film wrapping apparatus, means (8) for ejecting a wrapped goods aggregate (6') from the wrapping station.
