<p>Drum (300) for cutting linerless labels (2;102) from a continuous strip (1;101) and transferring the labels to a container (3) movable with a given trajectory and speed on a machine (4), comprising:
- a side surface (301)
- a coaxial and concentric sleeve (310) for centring the drum on an associated support spindle (311);
- at least one cutting blade (330) displaceable in a radial direction from a position retracted inside the drum into a position extracted outside the side surface of the drum itself;
- a fixed cam (320) relative to which the drum rotates and which presses against said at least one blade (330) so as to cause it to move out in a predefined angular position;
- a seat (312) which extends in the vertical direction (Z-Z) and is connected to the cam (320) and which is suitable for engagement with a corresponding fixed reference pin (313), situated outside the drum, in order to determine a predefined angular position of said cam (320);
- means (334) for recalling the blade (330);
- means (301a,350) for retaining the strip (1;101) against the side surface (301) of the drum (310).</p> |
