  • Patent number: 7040076
    Abstract: In a method for packaging an object using a hose-shaped stretch foil having laterally extending folds guided axially with respect to the stretch foil and along a length of the object, a foil hood sized to a shape of the object to be packaged is formed, which hood is reefed onto several gripper devices movable in essentially horizontal direction, of a lifting frame movable in essentially a vertical direction. The reefed foil hood is tentered in an essentially horizontal direction by the movement of the gripper device such that the tentered opening of the foil hood is larger than the contour of the object to be packed and wherein the foil hood is expanded in essentially horizontal direction. The foil hood is then pulled over the object by the essentially vertical movement of the lifting frame, wherein the foil hood is pulled off from the gripper device and is expanded in essentially vertical direction.
