DEFINITION

Classification: 72/470

Including tool couple or die couple (e.g., opposed die faces):

(under subclass 462) Apparatus comprising two tools disposed opposite one another such that work may be located therebetween.

(1) Note. Patents placed in this and indented subclasses disclose a tool-couple wherein the tools may be fixed or movable relative to each other during use, but in either case it is clear from the disclosure that the tools cooperate with each other to form a tool-couple.
