Abstract

Viene descritto un dispositivo di taglio per eseguire tagli e/oppure intagli su un nastro di materiale mobile (3). Questo dispositivo presenta un cilindro di taglio (26) supportato girevole, un portacoltelli rotante (27) con almeno un coltello (34), cooperante con il cilindro di taglio per effettuate il taglio con una forza di taglio preassegnata, e mezzi per guidare il nastro di materiale (3) fra il cilindro di taglio e il portacoltelli. In una parte periferica del portacoltelli (27), contenente il coltello (34), è previsto un allargamento radiale (38) ad esempio nella forma di un segmento anulare (39). Portacoltelli e cilindro di. taglio sono disposti reciprocamente in modo che la superficie di accostamento a pressione (41) dell'allargamento radiale (38) con la rotazione del portacoltelli, già prima che il coltello incontri la superficie del cilindro di taglio, con unaA cutting device for making cuts and / or notches on a strip of mobile material (3) is described. This device has a rotationally supported cutting cylinder (26), a rotating knife holder (27) with at least one knife (34), cooperating with the cutting cylinder for carrying out the cutting with a predetermined cutting force, and means for guiding the belt of material (3) between the cutting cylinder and the knife holder. In a peripheral part of the knife holder (27), containing the knife (34), a radial enlargement (38) is provided, for example in the form of an annular segment (39). Knife holder and cylinder. cut are arranged so that the pressure approach surface (41) of the radial enlargement (38) with the rotation of the knife holder, even before the knife meets the surface of the cutting cylinder, with a
