    • 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).
    • 描述了用于从标签材料的幅材(3)切割标签(2)的切割单元(1) (1)包括安装在固定支撑结构(5)上的固定刀片(4),在使用中围绕轴线(B)旋转并且具有侧表面(7)的旋转鼓(6) 面向固定刀片(4)并接收标签材料的卷材(3),以及至少一个由旋转卷筒(6)的侧表面(7)承载的旋转刀片(8),并且在使用中循环地通过 (4)限定切割位置,其中固定刀片(4)和旋转刀片(8)在使用中与贴标签材料的卷材(3)的相对侧面配合以便将标签( 2)从网(3); 切割单元(1)还包括传感器装置(26),其在使用中检测与切割位置处的固定刀片(4)和旋转刀片(8)之间的距离或干涉相关的量(R),以及 致动器装置(27),其构造成根据由传感器装置(26)检测到的量(R)来调节固定刀片(4)朝向或远离旋转滚筒(6)的位置。
