A labelling machine comprising a carrousel and a plurality of plates, each plate being mounted on said carrousel and comprising: - supporting means for in use supporting a container to be labelled, said supporting means being in use associable with a bottom of the container and being mounted on said carrousel, the supporting means being rotatable relative to the carrousel about a first axis of rotation; and - a dragging element, comprising a tooth substantially insertable in use in a recess made in the bottom of the container supported by the supporting means, said tooth being movable relative to the supporting means between an engaged position, in which in use the tooth is substantially inserted in the recess, and a disengaged position, in which in use the tooth is not associated with the recess, the dragging element being rotatable about said first axis of rotation independently of said supporting means, and the tooth being off-centre relative to the first axis of rotation, characterised in that the labelling machine comprises thrust means positioned or positionable, in use, above each container to be labelled and able to push the container, supported by the supporting means, towards said supporting means, and further comprises for each plate coupling means, operatively associated with the tooth, for coupling the supporting means to the carrousel when the tooth is in the disengaged position, obstructing rotation of the supporting means relative to the carrousel, and for uncoupling the supporting means from the carrousel when the tooth is in the engaged position, allowing substantially free rotation of the supporting means relative to the carrousel. - supporting means for in use supporting a container to be labelled, said supporting means being in use associable with a bottom of the container and being mounted on said carrousel, the supporting means being rotatable relative to the carrousel about a first axis of rotation; and - a dragging element, comprising a tooth substantially insertable in use in a recess made in the bottom of the container supported by the supporting means, said tooth being movable relative to the supporting means between an engaged position, in which in use the tooth is substantially inserted in the recess, and a disengaged position, in which in use the tooth is not associated with the recess, the dragging element being rotatable about said first axis of rotation independently of said supporting means, and the tooth being off-centre relative to the first axis of rotation, characterised in that the labelling machine comprises thrust means positioned or positionable, in use, above each container to be labelled and able to push the container, supported by the supporting means, towards said supporting means, and further comprises for each plate coupling means, operatively associated with the tooth, for coupling the supporting means to the carrousel when the tooth is in the disengaged position, obstructing rotation of the supporting means relative to the carrousel, and for uncoupling the supporting means from the carrousel when the tooth is in the engaged position, allowing substantially free rotation of the supporting means relative to the carrousel.
