Abstract
Dispositivo (1) e metodo per la foratura, mediante ameno un fascio laser, di un materiale di incarto (2) di sigarette, in cui il materiale di incarto (2), in forma di nastro (3), viene traslato di fronte ad una testa focalizzatrice (9), la quale riceve un fascio laser impulsato (7) da una sorgente emettitrice (8) e lo focalizza sul nastro (3) spostando il fascio focalizzato (15, 16) su di un piano (a; b) disposto obliquamente alla direzione di avanzamento del nastro (3) stesso; un elemento parzializzatore (31a), realizzato in un materiale opaco alla radiazione laser, viene utilizzato per intercettare il fascio focalizzato (15, 16) in modo da limitarlo ad un settore circolare (18, 19) di ampiezza e forma prefissate, ed impedire al fascio (15, 16) stesso di colpire zone determinate del nastro (3).(Figura 1).
