ABSTRACT:
In the straightening machine of the invention, pivot plates are provided for mounting and pivotally supporting the upper movable rolls including the pinch rolls and the straightening rolls, whereby improved operation can be obtained. Expensive manufacturing costs can be reduced by employing pivot plates as disclosed by the present applicant. The task of maintenance is also reduced since fewer hours are needed for repairs whereas roll bearing capacity is materially increased. The pivot plates are pivotally supported by the side frames respectively having location adjacent the inside surface of the side frames and bearing units are mounted in the free ends of the pivot plates. It is possible to stagger the bearing units since the bearing units for the lower rolls are mounted for rotation in the side frames whereas the bearing units for the upper movable rolls are mounted in the pivot plates.
