Abstract: A foil hood is gathered into a stack of folds and then fitted over four fingers in inner positions of the fingers with the hood open downward. A holding device then clamps the hood against the fingers, the fingers are spread into outer positions to transversely stretch the hood, and then the holding device is disengaged. Finally the fingers are moved downward along the load such that the closed end of the hood engages on the top of the load and the hood is pulled upward fold-by-fold off the fingers through a predetermined position at which generally all of the folds have been pulled off the fingers to an end position at which the hood is stretched vertically over the load and all of the folds have been pulled off the fingers.

Abstract: An apparatus for wrapping an object having vertical sides and a top with a hood-shaped foil having a closed end and an open end fits the foil over the object in such a manner that excess-foil projections are formed at the closed end that project outward from the top of the object and an empty space is formed adjacent each projection between the foil and the object. The excess-foil projections are mechanically engaged and physically tucked between the object and the foil to push the projections into the respective empty spaces.

Abstract: An object having a top and sides is wrapped by first covering it with a hood-shaped foil such that excess-foil projections are formed that project from the top of the object past the sides of the object. Then the foil is pulled adjacent the projections out of contact with the object to form an empty space adjacent each projection between the foil and the object. The excess-foil projections are then tucked into the respective empty spaces, normally on the sides of the object.

The gathered film section (25) is stretched by means of a covering element (1) which can be displaced along the unit load or packaged goods (3), and is pulled over the unit load or packaged goods (3).

Abstract: An apparatus for wrapping an object with a stretchable foil hood has a pair of gathering fingers engageable upwardly into the foil hood, two gathering wheels outside the foil hood, rotatable about gathering-wheel axes, and engageable with the hood, and respective counter rolls inside the foil hood, aligned with the gathering wheels to pinch the foil hood, and rotatable about counter-roll axes below the respective gathering-wheel axes. The gathering wheel are rotated while in contact with the foil to form the foil into downwardly and outwardly extending folds.

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.

Abstract: The invention relates to an apparatus for shrinking a heat-shrink foil wrapped in particular about a palleted object stack. in order to improve on such an apparatus so that shrinking of the foil part projectingg past upper and/or lower face is pmproved and produces an optimal fold-free shrinkage, an apparatus for shrining a heat-shrink foil wrapped in particular about a palleted object stack comprises at least one shrink device movable vertically up and down on a frame to heat and shrink the heat-shrink foil, the heat-shrink foil projecting past the upper and/or lower edge of the object stack to form an upper and/or lower shrink formation, the apparatus further comprising at least one nozzle connected to a compressed air source and aimed centrally above and/or below the object stack and generally vertically directed thereat, each nozzle having outlet openings that extend at an angle not coinciding with the flow direction inside the nozzle and that are in an annular array.

Abstract: The invention relates to a method for drawing a flat tube of stretch film over a stack of goods items (8), in particular arranged on a palette, whereby a tube section (1) is pre-tensioned in the circumferential direction and then drawn over the stack of goods items (8) in the pre-tensioned state.

Abstract: The invention relates to a device for wrapping a stack of goods (1) with a section of a film (3) that is gathered, stretched and put over the stack on a gathering device (2). Said gathering device (2) has at least two gathering fingers (5) and at least one roller arrangement (4) on at least one connecting line between two adjacent gathering fingers (5). The roller arrangement consists of a gathering wheel (6) which is in contact with the exterior of the section of the film and of a counter-roller (7) which is in contact with the interior of the section of the film, and clamps the section of film between itself and the gathering wheel for the purpose of conveying it.

Abstract: The invention relates to a device and a method for introducing projecting elements (5) belonging to a section of a film (3) which surrounds laterally and at least partially the upper side of a stack of products (1) and which is adjacent to the stack of products in said area. In order to prevent the projecting elements, also known as tips or caps, from becoming fixed to the sides or to the upper side of the stacks of products, the triangular projecting elements, which are arranged in the region of two opposite-lying edges of the upper side of the stack of products and which emanate approximately in the corners of the stacks of products, are introduced into the area arranged between the stack of products and the section of the film, after the pile of products is enveloped.

Abstract: A package is wrapped with foil by forming a curtain of two foils pulled from respective supplies with the curtain extending transversely across a conveyor path at a wrapping station and displacing a package to be wrapped in a forward transport direction along the path into engagement with the curtain and through the station so that the foils extend downstream past the package. Then a pair of double-weld beams are moved together on opposite sides of the foils downstream of the station to press and weld the foils together downstream of the package while at the same time the package and beams are relatively displaced in the direction toward each other as the beams are moved together to reduce tension in the foils created by inward movement of the beams.
