  • These chocks are supports that can be moved in a direction parallel to the clamping plane, between the amounts of the cage.
  • balancing cylinders allow the displacement of the chocks of the intermediate rolls. These balancing cylinders allow to change the relative position of the chocks and their cylinder, allowing among other things, to open the cage to facilitate the engagement of the product to be rolled, or to move these elements to facilitate disassembly of the cylinders. These balancing cylinders can also help to arch the intermediate cylinders.
