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 method and a device for multi-sided wrapping of irregularly shaped objects, such as auto-mobiles (2), with a film (3) which can be shrunk with heat treatment and which provides protection for transportation. Said film (3) is configured to correspond approximately to the shape of the object and in a hood shape. The film is placed on the object and then shrunk exactly to fit the object with heat treatment, using a heat device. The invention aims to provide a method for multi-sided wrapping of irregularly shaped objects that can be carried out within shorter cycle times. In order to heat-treat different areas of the object, e.g. different regions of a vehicle front or a vehicle rear, at least part of the heat treatment is carried out by a heating device (7) which is located at an angle to the direction of transportation of the conveyor device (5) and which is fixed in its position and alignment.

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: 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.

Abstract: An apparatus for wrapping a stacked-good unit with a shrink-foil wrap with a frame forming a portal, with a conveyor extending through this portal for the stacked-good unit, with drivable shrink-foil rolls whose foil webs are connected together at their ends and form a shrink-foil curtain in the portal and double-weld beams movable opposite one another and arranged on both sides of the portal. To facilitate replacement of the shrink-foil webs, the axes of the shrink-foil rolls extend horizontally and rerouting devices are provided for the coil webs running to the curtain from the shrink foil rolls.

Abstract: An apparatus for displacing a plurality of objects from a pickup station to a deposition station offset horizontally from the pickup station has a support movable in a horizontal transport direction between a position directly above the pickup station and a position directly above the deposition station, an elongated lift plate underneath the support and provided with grabs for picking up and releasing the objects, a flexible belt having a lower end extending in the direction and secured to the lift plate, a drive on the support for paying out and winding in the belt and thereby raising and lowering the plate, and rigid links connected between the plate and the support for inhibiting movement of the plate perpendicular to the direction.

Abstract: A process is disclosed for removing a shrink wrapping drawn over a stack of goods. The shrink wrapping is vertically cut at one side of the stack of goods, one edge of the cut is held and secured to a winding spindle, and the winding spindle is then guided around the stack of goods so that the shrink wrapping is winded on the winding spindle that rotates around its longitudinal axis. Also disclosed is a device for carrying out the process.

Abstract: Goods are packaged by first placing a thermoplastic lower foil atop a pallet with edges of the foil projecting laterally past the pallet and then stacking goods on the pallet atop the foil on the pallet within the edges of the foil. The lower edge of a downwardly open heat-shrinkable foil hood is held as the hood is fitted downward over the stack on the pallet until the lower edge is generally below the stack. This lower edge is then gripped below the stack and the foil hood is shrunk from top to bottom around the stack while continuing to grip the lower edge below the stack. Finally the foil hood is welded to the outer edge of the lower foil. Thus when the grippers are carried on the same vertically displaceable frame as the heater/blowers it is possible for the grippers to release and move upward before the top-to-bottom shrinking of the hood. During such shrinking the clamps will prevent the hood or sack from riding up too much.

Abstract: A rectangular cross-section housing is provided for an apparatus generating hot gas to shrink a plastic film. A burner is located close to the upper small end of this housing while an outlet nozzle is provided at the lower small end and the gas flows at an obtuse angle from the burner to the outlet. The burner is flanked by lamellae and a venturi action draws cool air between the lamellae and the burner, additional cool air passing between the lamellae and the vertical housing walls. Cold-air nozzles are provided within the housing as well.

Abstract: The apparatus for shrinking a shrinkable cover to enclose a palletted stack of goods comprises a shrinking device, a conveying system for the palletted stack of goods transported past the shrinking device, a lifting device positioned under the shrinking device for raising the palletted stack of goods and a suction device positioned in the vicinity of the lifting device. The lifting device is located astride the path of the conveyor system thereby eliminating below ground conveyors in favor of driverless automatically controlled floor conveying devices. Part of the lifting device is at least one raisable and lowerable support movable under a palletted stack of goods being guided on the conveyor system. The support has seat members projecting from it for the palletted stack of goods and the seat members are movable from a horizontal into a vertical orientation, especially by rotation of the support about its longitudinal axis.
