(under subclass 414) Device wherein cross sections through the mating tool surfaces, taken in planes parallel to any given reference plane intersecting the surfaces, show identical contours.
(1) Note. The tool face in this subclass have "singly curved" surfaces; they may comprise flat sections, dihedral angles, arcuate, or gee sections, etc., all aligned in the same direction. Such tools effect "simple" angular or contour
bending, i.e., without bulging, dishing, or warping of the work surface (see appended diagram).

(2) Note. Work-shape-conforming recesses may be present in the tool faces,
with the same restrictions as expressed in the definition and notes of subclass 414.

319+, for the combination of a nondeforming work-clamp having a die surface extension, and a pivoted tool with complementary die face of constant profile. 379.2+, for a process of deforming sheet material which may employ complementary die faces of constant profile.
