The SAMAS AURORA 500 model is a single INDEX monobloc machine that provides for the movement of the bottles through a conveyor belt towards an alternating step star that transports the bottle to the exit belt for the following through the product filling stations, pre-screwing and capping, labeling and packaging phases. The machine's processing cycle includes four types of controls: presence of the bottle on the star, presence of the cap on the linear feeder of the pre-screwing, presence of the cap screwed on the bottle after the capping station, maximum level of bottle exit
