Class Information
Number: 72/382
Name: Metal deforming > By relatively movable offset tool-faces (e.g., for bending or drawing) > Embodying three or more coacting relatively movable tools (i.e., tool complex) > Comprising yieldable tool or face portion
Description: Comprising yieldable tool or face portion: Device wherein the face of one of said tools is so constructed, mounted, or connected to an actuating power train, that during a metal-deforming operation a portion of said face, while in contact with work, is deflected or bodily displaced with respect to another portion of said face.
