An apparatus for producing, bagging and dispensing ice has an ice supply station, an ice collection station, a film supply, a bag forming station, and an ice transport device to transport ice from the collection station to the bag forming station. A controller controls supply of two superimposed film layers to the bag forming station, bag forming, and ice supply to the bags. A bag is partially formed from the superimposed film layers by a sealing device at the bag forming station, and ice is transported from the ice collector into the partially formed bag. The remaining open portions of the bag are sealed when sufficient ice has been supplied to the bag, which is then separated from the film supply for discharge into a storage and freezer compartment. The preceding steps are repeated until the storage and freezer compartment is filled to a predetermined level with bags of ice.
