Abstract
An arrangement for sliding and shrinking a hood of shrinking foil over and onto a stack formed by a number of packaging objects. The arrangement includes a vertically movable frame with shrinking devices provided in the upper region of the frame and gripping elements for grasping and pulling down the lower edge of the shrinking foil. A lifting device arranged centrically underneath the stack serves to raise the stack from a conveying device which transports the stack into and out of the arrangement according to the invention. The lifting device raises the stack so that the lower edge of the hood of shrinking foil can be shrunk onto the stack up to the region of the conveying device. Subsequently, the lifting device is lowered. The vertical distance between the gripping elements and the shrinking devices is adjustable.
