Class Information
Number: 72/389.8
Name: Metal deforming > By relatively movable offset tool-faces (e.g., for bending or drawing) > With tool motion in fixed path > Between and co-planar with opposed tools > Fluid pressure actuated (i.e., hydraulically or pneumatically actuated) > Pivotable opposed tools
Description: Device wherein the two contraposed tool-faces turn about an axis as the workpiece is deformed.
