In particular, it is possible to act so that the conveying velocity (vapp) of the articles A by the screw 142 is a sub-multiple of the initial advancing velocity (vin) so that the output flow of articles A includes groups of stacked articles. Each group includes a number of articles A equal to the ratio between the initial advancing velocity (vin) and the conveying velocity (vapp) of the screw 142.
