Abstract
Screw caps (2) are fitted to the necks of respective containers (3) by a unit comprising a carousel equipped with a platform on which the containers are placed, a frame positioned above the platform, and a drive system by which the platform and the frame are set in rotation about a main vertical axis. The unit comprises at least one screw capping device (7) associated with the rotating frame of the carousel, located above a respective container (3) and equipped with a gripping mechanism (9) lockable onto the cap (2) of the container, also a first motion-inducing linkage (25) by which the gripping mechanism (9) is caused to rotate about an axis (Y) parallel to the main vertical axis, and a second motion-inducing linkage (37) by which the gripping mechanism (9) is moved toward or away from the respective cap (2). The screw capping device (7) is packaged internally of a box-like body (10) associated removably with the rotating frame and housing the gripping mechanism (9).
