Abstract: A machine for righting and aligning articles comprises at least one housing able to receive an article in a lying position, pre-oriented, and let it fall into a drop chute; end stop and support elements in the housing to hold a differentiated configuration of the article during its falling; a partition wall dividing the drop chute into two compartments; and a first diverter plate actuated to change position and direct the articles towards one and the other of the compartments, in an alternating manner. It includes two further partition walls dividing the two compartments into four subcompartments, each one for one article upright positioned, and a pair of second diverter plates actuated to change position and direct the articles towards one and other of said subcompartments, in an alternating manner.
