Abstract
L'invention concerne l'industrie du laminage. Le dispositif faisant l'objet de l'invention est caractérisé en ce qu'il comporte des soupapes de pression commandées 3, à raison d'une par capteur de force hydraulique, la chambre de laminage desdites soupapes étant mise en communication avec une source 5 de pression variable de fluide, individuelle pour chaque partie du dispositif disposée de l'un des côtés de la cage 1, ainsi qu'avec la chambre médiane 1 des régulateurs de pression 4 à trois chambres, tandis que leur chambre de commande e est mise en communication avec la chambre a du capteur de pression hydraulique. L'invention s'applique notamment aux laminoirs produisant des tôles et des bandes.
