<p>The disclosure involves an apparatus (1) for the flying-shear cutting of thin-layer material, reeled off from a coil, by laser radiation, especially metal strips, fabrics, synthetic resins, paper, cardboard, and composite materials. In order to be able to crosscut individual strip sections (17) at high speeds without having to arrest the strip (2), the apparatus (1) consists of a traverse (3) arranged at an angle to the travel direction (a) of the strip (2), this traverse being rotatably supported and driven about its longitudinal axis of symmetry (4). Mutually opposed guides (5) for two separately operable laser cutting heads (6) with nozzles (7) are mounted in parallel to the longitudinal axis of symmetry (4) of the traverse (3). The laser cutting heads (6) are in each case movable separately or individually by way of the guides (5). The nozzles (7) of the two laser cutting heads (6) are arranged to face away from each other and project through longitudinally extending slots (8)in an outer housing (9)of the traverse (3).</p> |
