<p>The device comprises at least a first series of slides ( 21 ) each carrying a respective cutting tool ( 9 ). The slides are adjustable and clampable in pre-established positions along a beam ( 11 ) extending more or less transversely with respect to the direction of feed of the web material. Moreover, a system to clamp the slides along said beam and a translation member ( 71 ) to translate and position said slides along the beam are provided. The clamping system comprises, for each slide, a pressing member ( 33 ) elastically stressed against a fixed surface ( 29 A) integral with the beam, while the translation member comprises an actuator ( 74 ) cooperating selectively with one or other of said pressing members, to release the pressing member from the fixed surface and draw the slide by means of the translation member and position it along said beam.</p> |
