A labelling and/or marking machine ( 3 ) comprises a carousel ( 4 ) rotatable about a vertical axis ( 5 ), equipped peripherally with a set of pedestals ( 8 ) driven by respective motors ( 37 ) and supporting single containers ( 2 ), also applicator and/or marker devices ( 26, 27 ) occupying positions along a conveying path ( 17 ) followed by the containers ( 2 ). Each pedestal ( 8 ) is flanked by a corresponding CCD image sensor ( 31 ) such as will scan the lateral surface ( 29 ) of the container ( 2 ) to detect and recognize a known outline ( 32 ) presented by the surface ( 29 ), whereupon the pedestal ( 8 ) is made to rotate through a predetermined angle and thus bring the relative container ( 2 ) into the position required by the applicator and/or marker devices ( 26, 27 ).
