A device 10 for generating an output flow of articles A, starting from a flow of incoming articles (such as single use absorbent pad products A) having a given advancing velocity vin, includes a screw conveyor 14 to receive longitudinally the flow of incoming articles A. The conveyor in question comprises at least one screw 142 the helix of which is susceptible to interact with the advancing of articles A to determine their conveying by the screw 142 itself. The rotational velocity of the screw 142 is adjustable for varying the conveying velocity of the articles A with respect to the initial advancing velocity. 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. |
