METHOD AND APPARATUS FOR THE FORMATION AND DISCHARGE OF ORDERED GROUPS OF PRODUCTS, IN PARTICULAR ROLLS OF PAPER

摘要

The formation of a group (2) of rolls (3) of paper arranged according to a first number (h) of overlaid layers (4) is performed by feeding the layers (4) onto an elevator platform (8) by means of at least two feed conveyors (11) positioned one on top of the other; the method providing for initial loading onto the platform (8) of a number of layers (4) at the most equal to the number of feed conveyors (11), lowering of the platform (8) by a distance equal or slightly greater than the height of the layers (4) just loaded and, lastly, loading onto the platform (8) and onto the layers (4) already loaded of a number of layers (4) at the most equal to the number of feed conveyors (11).
