Abstract

La présente invention concerne un dispositif de flexion pour les cylindres d'une cage de laminoir à plusieurs cylindres, qui comprend des blocs de flexion fixés côté entrée et côté sortie entre les empoises de cylindre et les ouvertures d'ossature. Les blocs de flexion supérieurs et inférieurs sont reliés au moyen d'un cylindre à piston et/ou au moyen d'un système mécanique de positionnement vertical, de préférence au moyen d'un vérin de levage. Selon cette invention, d'un côté une force de flexion peut être appliquée par le cylindre à piston (7) dans les blocs de flexion reliés du même côté (5, 5a) et d'un autre côté les blocs de flexion opposés (5', 5a') peuvent être positionnés et bloqués par le vérin de levage (10).
