Arrangement for increasing safety of material processing machine, especially cutting machine, has contactless semiconducting switching elements in series for triggering switching

摘要

The arrangement has switchable arrangements, especially couplings, valves or magnets, for the drives for a pressure beam, a mechanical overrun lock for the cutting blade and/or a blade carrier. At least two contactless semiconducting switching elements (V1,V2) connected in series are arranged for triggering the switching process.
