Abstract
Sur une presse hydraulique à vérin-moteur 5, le coulisseau 4 est levé, en course rapide et jusqu'au voisinage de la pièce à découper, par des verins auxiliaires à course rapide 7 qui amènent le coulisseau au voisinage de la pièce à découper 10. S'il existe un obstacle 24 dans la zone de l'outil 2, 3, il en résulte pour les vérins auxiliaires 7 une augmentation de pression ou une diminution de vitesse de débit qui sont transformées en signaux qui stoppent le mouvement du coulisseau.
