INVENTORS: BENZ GOTTLIEB and HANS-ULRICH STAUBER INVENTION: METHOD OF, AND APPARATUS FOR, WRAPPING OBJECTS, ESPECIALLY QUADRANGULAR BLOCK-LIKE OBJECTS WITH A WEB-LIKE WRAPPING MATERIAL 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 foil web. The two runs of the loop are releaseably held at their ends by related holding means. These two foil runs 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 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.
