Apparatus for applying terminals from a carrier strip to wire, said apparatus comprising a frame, die holder means on said frame, die carrier means on said frame mounted for movement toward said die holder means to a terminal crimping position and away from said die holder means to a terminal releasing position, strip feeding means on said die holder means and mounted for movement in one direction to longitudinally step a carrier strip through the space between said die holder and carrier means and in another direction to displace the strip transversely away from and toward said die holder and carrier means, and operating means connected between said die carrier means and strip feeding means to move the latter intermittently in said one direction when said die holder and carrier means are out of said crimping position and in said other direction when said holder and carrier means are in said crimping position, to crimp successive terminals and dislodge crimped terminals from said carrier strip, said die carrier means comprising a crosshead reciprocable toward and away from and having a die receiving groove opening toward said die holding means, said crosshead being provided with a cavity communicating with the interior of said groove remote from said die holding means, a rotary fine adjustment cam of varying diameter selectively positionable in said cavity to locate a desired diameter toward said groove, a rough adjustment block slidable in said groove away from said die holding means to a position in limiting abutment with said fine adjustment cam at said desired diameter, said block having a cavity opening into said groove away from said fine adjustment cam, and a rotary rough adjustment cam of different diameters selectively positionable in said block cavity to locate a desired diameter toward said groove, whereby said groove is adapted to receive a die selectively positioned in said groove by engagement with a desired diameter of said rough adjustment cam.
