Each capping assembly (11) presents a gripping mechanism (17) positionable so as to engage a relative cap (3) when the assembly (11) is in the second position, and rotatable about a respective secondary axis (17a) in such a way as to screw the cap (3) onto a threaded neck (4) of the relative container (2). The unit (1) further comprises first motors (14) by which the capping assemblies (11) can be raised and lowered one independently of another, and second motors (18) by which the gripping mechanisms (17) can be rotated one independently of another.
