ABSTRACT:
The package to be wrapped is moved during a first step towards a foil section which is extended under tension transversely relative to the direction of movement of the package. During a further course of movement of the package the aforementioned foil section is applied to three sides around the package in a substantially U-shape. Subsequently, a loop is formed from the web-like foil by entraining means which act on the web-like foil. The two runs of the loop are releasably held at their ends by related holding means. These two loop runs of the foil are separated from each other using a cutting knife. The foil section thus produced, which runs along the rear side of the package, has a length which is greater than the height of the package. An end section of this foil section of greater length and which protrudes past the package is now displaced towards and against the underside of the package. A wrapping material preferably consisting of a polyvinylidene chloride foil having self-adhesive properties is used as the web-like foil.
