<p>The invention relates to a collision-preventing control system for two cutters, to be moved towards one another, of a computer-controlled cutting installation. With this control system, it is possible to detect the actual position of each cutter during the cutting process. The proximity of the two cutters can be determined and compared with a previously set tolerated proximity via comparators arranged in the arithmetic unit. As soon as the tolerated proximity is reached, the control system switches the cutting installation off. In addition, an electrical safety circuit is specified, by means of which it is not possible for the cutting installation, after being automatically switched off, to start up again automatically. <IMAGE> </p> |
