(under subclass 274) Subject matter which functions to assist the "drawing" of the work by propelling the work, or the die, relative to the pulling means.
(1) Note. The additional means of this subclass may (a) "push" the work into the closed die, or (b) move the closed die over the work (both of these operations being frequently described in the art as "threading" the die) before, during, or after the action of the pulling means.
