  • Patent number: 4823539
    Abstract: In an apparatus for forming, filling and closing packages made of cardboard, cassettes for receiving the package are provided, which may be rearranged in differing processing positions. These cassettes are designed in such a way that they may be either exchanged for one another altogether, or reset for various format sizes. With such a device, format resetting, which has heretofore required considerable retooling times for such devices, may be achieved in a very short time and without great difficulty.
