Abstract

Elle comprend notamment un émetteur 1 de rayonnement modulé mobile qui passe par balayage périodiquement, avec une fréquence élevée, sur la zone à protéger et se trouve achemine sur un récepteur photoélectrique 9 qui fournit, en présence d'un obstacle dans la zone à surveiller, un signal de désactivation des commandes de la machine d'exploitation et comprend par ailleurs, un circuit générateur d'impulsions propre à déterminer la suppression d'une ou plusieurs impulsions du faisceau émis à partir de l'émetteur photoélectrique 1 pour effectuer la surveillance du fonctionnement des commandes pendant le balayage, cette suppression étant obtenue au moyen d'un émetteur photoélectrique 12 coopérant avec un photo-récepteur 16 et asservi à une piste supplémentaire de commande associée au rotor 4 de balayage. Application aux presses.
