摘要： There is provided a bending mechanism for use in the fabrication of metal and other materials. The bending mechanism includes a clamping structure to secure the material to a supporting plate with the portion of the material to be bent projecting from the clamping structure. A bending plate is then brought into contact with the material and rotated about the edge of the supporting plate to bend the material to the desired angle. Multiple bending mechanisms can be utilized for longer and/or multiple bends of the material.
