Labelling machine with carrousel

A labelling machine with a carrousel comprising a carrousel (3) and a plurality of plates (4), each plate (4) being mounted on said carrousel (3) and comprising:

• supporting means (13) for in use supporting a container to be labelled, said supporting means (13) being in use associable with a bottom of the container and being mounted on said carrousel (3), the supporting means (13) being rotatable relative to the carrousel (3) about a first axis of rotation;
• and
• a dragging element (14), comprising a tooth (15) substantially insertable in use in a recess made in the bottom of the container supported by the supporting means (13), said tooth (15) being movable relative to the supporting means (13) between an engaged position, in which in use the tooth (15) is substantially inserted in the recess, and a disengaged position, in which in use the tooth (15) is not associated with the recess, the dragging element (14) being rotatable about said first axis of rotation independently of said supporting means (13), and the tooth (15) being off-centre relative to the first axis of rotation;
• characterised in that it comprises for each plate (4) coupling means (41), operatively associated with the tooth (15), for coupling the supporting means (13) to the carrousel (3) when the tooth (15) is in the disengaged position, obstructing rotation of the supporting means (13) relative to the carrousel (3), and for uncoupling the supporting means (13) from the carrousel (3) when the tooth (15) is in the engaged position, allowing substantially free rotation of the supporting means (13) relative to the carrousel (3).
