The rolls in a straightening machine are arranged in an upper and a lower row each being associated with a gear, and these gears establish groups of three wherein one gear pertains to one row and drives the two others pertaining to the respective other row. The one gear of each group is on a shaft that is driven by a larger gear and these larger gears are correspondingly arranged in two rows. One of these larger gears receives driving input through a speed reducing gear from a drive motor, and meshes two of the larger gears but of the respective other row. A bypass gear drivingly links that one larger gear with a fourth one but being associated with the same row. The fourth and one of the two gears mesh with play. |
