<p>In labelling stations in a labelling machine, it is known to have gluing segments mounted eccentrically upon a carrier and rotating eccentrically about their own axes, a pressure element to transfer the label from the gluing element to the object and a gripping element. In this invention, a cam is used for controlling the rolling of each pressure element upon the surface of the object to be labelled by adjusting the peripheral velocity of the pressure element. Similarly, a second cam makes it possible to adapt the device to the different diameters of the object to be labelled, without displacing the centre of rotation of the labeltransfer mechanism in relation to the track conveying the object.</p> |
