Abstract (en)
There is described a cutting unit (1) for cutting labels (2) from a web (3) of labelling material; the cutting unit (1) comprises a stationary blade (4), mounted on a stationary support structure (5), a rotary drum (6), rotating, in use, about an axis (B) and having a lateral surface (7) facing the stationary blade (4) and receiving the web (3) of labelling material, and at least one rotary blade (8) borne by the lateral surface (7) of the rotary drum (6) and cyclically passing, in use, by the stationary blade (4) to define a cutting position, wherein the stationary blade (4) and the rotary blade (8) cooperate, in use, with opposite sides of the web (3) of labelling material so as to separate a label (2) from the web (3); the cutting unit (1) further comprises sensor means (26), detecting, in use, a quantity (R) correlated to the distance or interference between the stationary blade (4) and the rotary blade (8) at the cutting position, and actuator means (27) configured to adjust the position of the stationary blade (4) towards or away from the rotary drum (6) as a function of the quantity (R) detected by the sensor means (26).
