ABSTRACT:
The invention relates to a method for wrapping unit loads or packaged goods (2) using a section of elastic film (8) that is at least approximately hood-shaped, whereby the section of film is gathered and pulled over the unit load or packaged goods. The invention aims to provide a significantly faster packaging method of this type, which can be used in branches of industry with high production figures, e.g. white goods (dishwashers, refrigerators etc.). To achieve this, the section of film is gathered by a gathering device (3), then taken by a covering device (6) that can be displaced separately and subsequently pulled over the unit load or packaged goods, in particular being stretched beforehand. Another section of film can be gathered by the gathering device, while the previous section of film is still being pulled over the unit load or packaged goods.
