ABSTRACT:
A device for forming groups of products in conveying systems, in particular for automatic packaging machinery, includes a path of conveyance in which, in operation, an array of products advances along a direction of conveyance with the products in contact with each other. A separator element is able to be inserted in a predetermined area of the conveyance path to separate a group of products downstream of the separator element with a predetermined dimension in the direction of advance. At least one nozzle is arranged to emit at least one jet of gas, such as air, on the array of products to distance the products at least partially from each other in the predetermined area before inserting the separator element.
