Claims

[Scope of utility model registration request]

A group of large-diameter rollers in which large-diameter rollers are arranged in a zigzag pattern on the upper and lower sides, and small-diameter rollers are arranged in a zigzag pattern in the upper and lower sides of the large-diameter roller group on both sides or either side of the large-diameter roller group. It has a small-diameter roller group, the lower large-diameter roller group and the small-diameter roller group are used as a bottom frame, the upper large-diameter roller group is used as a top frame, and each small-diameter roller of the upper small-diameter roller group is backed up. Each of the upper small diameter roller frames is suspended by a balance cylinder and is interposed between the small diameter roller frame and the top frame. At the roller level of the metal plate material in which the upper small-diameter roller frames can be raised and lowered independently by a wedge frame, an upwardly sloped surface is formed on the upper surface of the upper small-diameter roller frame from the center outward. The wedges are symmetrically formed in a step-like manner so that the level of the sloped surface of the wedge becomes gradually lower as it goes outward from the center, and the sloped surface that matches the wedge formed on the upper surface of the upper small diameter roll frame is formed. A pair of independent wedge frames each having a wedge formed on the lower surface in a step-like manner are inserted symmetrically between the upper small diameter roller frame and the top frame, and are connected to the rear end of the wedge frame. A roller leveler made of metal sheet material, characterized in that each cylinder is provided with a cylinder for raising and lowering an upper small-diameter roller.
