Abstract
Appareil de cisaillage d'une colonne de matière à l'état plastique au moyen de lames pouvant se rapprocher et s'éloigner l'une par rapport à l'autre en ligne droite. Il comporte un vérin hydraulique 18 ayant un piston 246 et une tige de commande 20 et un dispositif qui commande l'écoulement du fluide vers le piston et qui comprend un élément de commande de retour normal, actionné par la tige de commande 20 et destiné à déclencher le retour du piston de sa position de cisaillage vers sa position d'ouverture après que les lames ont atteint leur position de cisaillage, et un dispositif de retour automatique 398, 410 qui ramène le piston 246 vers la position d'ouverture dans le cas où les lames de cisaillage n'atteignent pas tout à fait la position de cisaillage et ne permettent donc pas au dispositif de commande de retour normal 470, 472, 336, de déclencher le retour. Application au domaine du travail sur les matières plastiques.
