ABSTRACT:
A wheel rim forming machine including a fixed frame having four vertically extending columns. Due to the frame structure, the forming force acting at the top and bottom rolls of the machine are borne evenly through tensile forces acting in the four columns. Thus, no bending deformation occurs in the columns. Further, because the columns are not exposed to bending forces, they can be formed with a relatively small cross-section and thus the frame structure is compact. Therefore, access to the guide rolls and their support structure is facilitated and high grade adjustment of the guide rolls is possible.
