Abstract
The supporting grate of a laser cutting machine is formed of swinging supporting arms which are swung from a horizontal supporting position to a lowered intermediate position or to a completely lowered, approximately vertical position. When the laser beam is travelling through their area, individual supporting arms are lowered to the intermediate position so as not to disturb the cutting operation, to avoid damages of the supporting arm and to prevent damages of the underside of the workpieces by reflections of the beam. Cutout pieces are continually removed by lowering the supporting arms under said pieces so that said pieces are dropped onto a conveyor belt and carried off. As soon as all pieces are cut out, all supporting arms are lowered, whereby the remaining grid is dropped onto the conveyor belt and can be carried off. A coordinated program control for the displacement of the cutting head and the movement of the supporting arms is provided.
