Loading the bag chain in a bag indexing drive unit involves simply placing the cassette 5 into position with the spools 8 and 9 engaged with parallel drive dogs 11 and 12, after which operation of a drive motor 15, driving the dogs 11 and 12 through a differential unit 14-22 indexes the bags 2a, 2b, 2c . . . and winds up the tapes 3 and 4. Upon complete consumption of the bag chain, the cassette can be removed and replaced by a fresh cassette with the tapes outside the cassette and carrying the imbricated bags.
