Abstract

L'invention concerne l'industrie du laminage. Le dispositif faisant l'objet de l'invention est du type comprenant des capteurs de pression hydrauliques 12 sensibles à l'effort de laminage, placés sous les empoises 9 d'au moins l'un 10 des cylindres 3, 10 de la cage 4 et ne subissant pas l'action des vérins hydrauliques 1 assurant la mise de la cage 4 en précontrainte et communiquant avec la cavité desdits capteurs de pression hydrauliques et avec une source 14 de fluide à pression constante, et est caractérisé en ce que chacun desdits vérins hydrauliques comporte deux chambres dont l'une B communique directement avec la cavité 16 du capteur de pression hydraulique 12 correspondant, et l'autre, directement avec ladite source de fluide à pression constante. L'invention s'applique notamment aux laminoirs à tôles et à bandes.
