A rolling mill (100) includes:—a rolling-mill cage (10) containing a plurality of cylinders, including two working cylinders (12) and two pairs of intermediate cylinders (13), a main gate (30) on the front face of the rolling mill (100) for accessing all the cylinders, a device (20) for the lateral movement of the intermediate cylinders (13) of the push-push type including first and second pairs of hydraulic actuators (22, 22′, 21, 21′) each configured so as to exert a thrust force (P) to allow a lateral movement of the intermediate cylinders (13), a removable small gate (40) fixed to the main gate (30), allowing access to the cylinders (12) and (13), and integrating the second pair of hydraulic actuators (21, 21′) so that opening and closing the small gate (40) does not interfere with the opening and closing of the main gate (30). |
