Abstract
In a method for packaging objects a means for generating a foil hood 6 and several gripping means 8 for gripping and tenting said foil hood 6 are provided for. Said foil hood 6 is pulled onto several bow-like frame sections 8a and bow supports 8b and is tented such that said tented opening said foil hood 6 is larger than the object to be packed, wherein said foil hood 6 is pulled over said object with a certain extension transverse to the plane of the tented opening of said foil hood. Subsequently, said foil hood 6 is pulled over said gap 15. Thereby, an increased resistance occurs during pulling-off. The vertical stretch is improved. Simultaneously, said foil is particularly safely held when creating the understretch during the pulling-over end phase.
Claims29
A method for packaging objects of a stack of goods (1) on a pallet in particular, with a hose-shaped stretch foil which is reefed on several gripping means (8) with bow-shaped frame sections (8a) and frame supports (8b) of a lifting frame movable in vertical direction and tented by means of said gripping means in such manner that the tented opening of said foil hood (6) is larger than the horizontal projection of the good to be packed and wherein said foil hood (6) is pulled over said object with a certain extension transverse to the plane of the tented opening of said foil hood, characterized in that said foil prior to leaving the respective gripping means (8) is guided over at least one recess (15) in the slide surface of said gripping means in order to increase the pulling-off resistance such that it is deflected with respect to its pulling-off direction.
An apparatus for packaging objects of a stack of goods (1) on a pallet in particular, with a hose-shaped stretch foil (6) and with gripping means (8) arranged on a lifting frame and formed by bow-shaped frame sections (8a) comprising essentially rounded foil contact surfaces, with bow supports (8b) and by reef rolls (10) which can be brought into contact therewith, for reefing and transverse stretching of said foil hood (6), said gripping means together with said lifting frame being movable in vertical direction along the objects to be packed, characterized in that said slide surface of said gripping means (8) at least one recess (15) is provided for, by which said foil can be deflected with respect to its pulling-off direction in order to enlarge the pulling-off resistance.
