Abstract

L'INVENTION CONCERNE UN APPAREIL DESTINE A PRODUIRE DES FAISCEAUX LUMINEUX PULSES A PARTIR D'UN FAISCEAU LASER PERMANENT ET FOCALISE. IL COMPORTE DES DISQUES AVEC DES FACETTES REFLECHISSANTES PERIPHERIQUES SEPAREES PAR DES PARTIES TRANSMETTANT LA LUMIERE. QUAND LES DISQUES TOURNENT ENSEMBLE, LES FACETTES EMETTENT DES FAISCEAUX LUMINEUX PULSES QUI SONT CONCENTRES PAR UNE LENTILLE COMMUNE. L'INVENTION S'APPLIQUE NOTAMMENT A LA PERFORATION DE MATIERES EN FEUILLE.THE INVENTION RELATES TO AN APPARATUS FOR PRODUCING PULSED LIGHT BEAMS FROM A PERMANENT AND FOCUSED LASER BEAM. IT FEATURES DISCS WITH PERIPHERAL REFLECTING FACETS SEPARATED BY PARTS TRANSMITTING LIGHT. WHEN THE DISCS ARE SPINNING TOGETHER, THE FACETS EMIT PULSED LIGHT BEAMS WHICH ARE FOCUSED BY A COMMON LENS. THE INVENTION APPLIES IN PARTICULAR TO THE PERFORATION OF SHEET MATERIALS.
