Shielding device for shielding of a laser processing machine for processing workpieces, preferably metal sheets (2) on a workpiece directed by a laser beam and/or a point of impingement of the laser beam on the workpiece comprises a shielding unit (11) comprising a shielding member (14), where the shielding member for shielding the laser beam or the point of impingement of the laser beam on the workpiece in a operating position on the workpiece is movable and where a front surface is formed at a free end of a shield member. Shielding device for shielding of a laser processing machine for processing workpieces, preferably metal sheets (2) on a workpiece directed by laser beam and/or a point of impingement of the laser beam on the workpiece comprises a shielding unit (11) comprising a shielding member (14), where the shielding member for shielding the laser beam or the point of impingement of the laser beam on the workpiece in a operating position on the workpiece is movable and where a front surface is formed at a free end of a shield member, which is in operating position of the shielding member facing an associated workpiece surface and at a desired orientation relative to the workpiece surface oriented substantially parallel to the workpiece surface, where a detecting device (5) is provided by, which the orientation of the end surface (19) of the shielding member in the operating position located relative to the workpiece surface is detectable. Independent claims are also included for (1) laser processing machine for processing workpieces, preferably metal sheets with a formed shielding device for shielding on the laser processing machine to a workpiece directed laser beam; (2) method for shielding of the laser processing machine for processing workpieces, preferably metal sheets on the workpiece directed by the laser beam and/or the point of impingement of the laser beam on the workpiece comprising moving the shield member, the shielding unit of the shielding device for shielding of the laser beam or the point of impingement of the laser beam on the workpiece into the operating position on the workpiece and the operating position in the moving shielding member with a free at one end of the shielding member formed on end surface of an associated workpiece surface is arranged oppositely and is aligned at a desired orientation parallel to the workpiece surface, where the orientation of the end surface of the shielding member located in the operating position is detected relative to the workpiece surface; and (3) method for processing workpieces, preferably metal sheets by the laser processing machine comprising directing the laser beam to the laser processing machine on the workpiece, and shielding the laser beam directed on the workpiece and/or its impingement on the workpiece by the above mentioned method.
