DEFINITION

Classification: 72/389.1

Between and co-planar with opposed tools:

(under subclass 386) Device including a first tool and an opposing second tool in which the first tool has a single tool-face* and the second tool has two contraposed tool-faces which lie in a plane which is parallel to the single tool-face, wherein the single tool-face passes between the contraposed tool faces to deform a workpiece thereon.
