A compacting device operates in the collecting zone to move the components closer together and place them at a second mutual distance that is smaller than the first mutual distance. A tray faces and receives from the collecting zone the group of components which have been placed close together. A pushing device pushes the components from the collecting zone into the tray. A movement device transfers the tray to the second operating station.
