| description | The present invention respects to a device and to a process of cutting and/or welding and/or marking bodies (3), at high speed and of long range, namely for plastic films, using laser technology. The process and the device use a beam (1) of coherent radiation, namely a laser beam, that sweeps the body(ies) (3) to be worked and that is focused on them by means of a focusing device (23) placed downwards from the source (0) of the said radiation, and are characterized in that the focusing element (23) is constituted by a cylindrical parabolic mirror (23) that is placed immediately upwards from the cited body(ies) (3) and that is swept by the said beam (0) accordingly to a direction substantially parallel to the one of a generatrix of said mirror (23). The cylindrical parabolic mirror may have only one cylindrical parabolic surface (231) or more and these may be approximated by elliptical surfaces, cylindrical or others. The beam sweeps the parabolic mirror (23) by the action of a rotating mirror (21) . |
