Abstract

L'invention concerne l'industrie du laminage. Le dispositif de régulation faisant l'objet de l'invention est caractérisé en ce qu'il comporte des soupapes de pression commandées 26, logées dans les vérins 2 à deux chambres, à raison d'une par verin 2, la chambre d'étranglement ou de laminage f de ces soupapes étant mise en communication avec la seconde chambre b des vérins 2 et avec une source individuelle 10 de fluide à pression variable, tandis que la chambre de commande d desdites soupapes est mise en communication avec la chambre c des capteurs de force 21. L'invention s'applique en particulier aux laminoirs produisant des tôles et des bandes.
