  • Patent number: 5636496
    Abstract: A procedure for winding a wrapper (1) around a piece of goods (2) includes the steps of pulling a shrinkable film (5) over the upper part of the goods, winding the wrapper around the goods so that the film is partly impacted under the wrapper, and cutting off and seaming the wrapper. The wrapper is unshrinkable relative to the film. Only the film is heated, and it shrinks and becomes tightened around the upper part of the goods. An apparatus includes assembly for pulling a shrinkable film over the upper part of the goods, assembly for winding a relatively unshrinkable wrapper around the goods, assembly for cutting off and seaming the wrapper, and a heating device for heating only the film wherein the heating device is disposed above the film whereby a hot air is blown against the film. The tightened film supports the upper part of the goods so that the goods cannot fan out during transport or delivery.
