Make the grid flight on the surface of the gravure cylinder manner and the device

摘要

(57) Abstract The rotary gravure cylinder (2) the hole (18) being method and the device in order especially to make quickly on the surface the pulsed laser beam (13) with, the laser beam is deflected, the optical lens (7) through, the gravure cylinder which it should process (2) is sent to the surface. Power of single laser beam pulse, although the said power the hole (18) removes the maximum capacity which is needed, adjusts with the kind of manner which is sufficient. Furthermore, the laser beam (13), the lens (7) it is deflected in optical axis by diffraction the optical acoustic modulator (8) with, individual laser beam pulse, these pulse powers, following to the capacity of the hole which it should form, is controlled the same modulator (8) by.
