Abstract
1391080 Cutting by lasers MESSER GRIESHEIM GmbH 22 Sept 1972 [22 Sept 1971] 43989/72 Heading B3V [Also in Division B4] A method of cutting a metallic or non-metallic workpiece by means of a laser beam comprises a supporting workpiece 1 on a plurality of pointed or knife-edge support elements 2 and cutting the workpiece by the laser beam. As shown in Fig. 1, the support elements, e.g. of copper or aluminium are separated by spacers and joined together by pins 3 so as to form a support unit 6. The open spaces beneath the workpiece can be connected to a vacuum source. In the modification shown in Figs. 3 and 4, the support elements are connected together to form the links of an endless conveyer for transporting the workpieces. In a further modification, the support elements may be joined to form a honeycomb grid or they may be in the form of pins having conical or pyramidal points. In operation the laser beam may be moved over a stationary support structure or vice versa.
