Abstract: Apparatus for arranging containers horizontally and in sequence comprises a hopper to which loose containers are fed, an elevator with pick-up teeth defining seatings on which, on the ascending branch of the elevator, containers are disposed in a horizontal position and maneuvered by an associated pushing device, and a drum near the top of the elevator containing housings moved in phase with the teeth so that the containers can be transferred from one to the other.The bottom of the hopper comprises a conveyor belt which conveys containers towards the foot of the ascending branch. Rotating arms staggered either angularly or heightwise below the top of the branch near the drum are placed to intercept between successive teeth of the ascending branch so as to either lay down or eject from the elevator containers carried by the pick-up teeth in incorrect positions.
