Selectors which can be worked alternately are placed along the advancement path of articles having different sizes. Each selector is constituted by a rake structure with L-shaped prongs which can be moved from an upper rest position, where the prongs do not interfere with the advancement of the articles along said path, to a lower pick up position where the prongs stop the advancement of the articles and then again to an upper discharge position, where the prongs, after having lifted the engaged articles, allow their conveyance towards collection places, such as piling hoppers.
