Class Information
Number: 72/414
Name: Metal deforming > By tool-couple embodying nonplanar tool-face > With complementary tool-faces (e.g., for embossing)
Description: Device wherein said tool-faces* have substantially equal areas and similar, but reversed, shapes or contours whereby they would be capable of substantially full surface contact (with allowance for the presence of uniform-thickness work therebetween), and including tool-faces which are complemental except for localized work-shape-conforming recesses or projections which have no disclosed deforming function.
