ABSTRACT:
An arrangement for manufacturing non-pelletized packaging units which are completely surrounded with shrinking foil. The packaging units are formed by several layers of objects which are stacked on top of each other in such a way that at least two parallel recesses are formed into which support members of a lifting device can engage. The arrangement includes a single shrinking foil application device and a single shrinking device forming a combined arrangement and having a common conveyor and support track. Shaping tools of a shaping device are permanently assigned to an appropriate conveyor surface of a turning device. The shaping tools can be moved into position for shaping the shrinking foil in the recesses after a first shrinking foil has been applied and shrunk onto the stack. After turning the stack, the shaping tools are moved into a release position. The shaping tools can then again be moved into position for shaping the shrinking foil in the recesses after the stack has been returned to the combined arrangement and a second shrinking foil has been slid over the stack and shrunk onto the stack and the stack has then again been moved into the turning device. The shaping tools can then be moved into a release position, so that the stacks can be laterally moved away.
