A packaging machine into which goods may be loaded and which can wrap the goods so loaded, by operation of its various pack-forming elements according to a predetermined sequence, has drive means which are essentially mechanical in character, the sequence being automatic and controlled principally by rotatable elements all deriving power from the same power unit. In one form, the machine is constructed so as to be suitable for making a succession of packs all of the same length, while in another form it is adapted for making packs which vary in length between one pack and another. In its latter form, the machine is particularly suitable for use at check-out points in consumer product selling establishments such as supermarkets.
