Abstract: This invention relates to an improved wire forming apparatus of the type wherein a pair of rotatable wheels are disposed alongside of each other, a plurality of pins are secured to each of the wheels about the periphery thereof, and mounting means rotatably support the wheels in such a manner that their axes of rotation are angularly disposed to each other. The improvement herein comprises looping means disposed adjacent to the peripheries of the rotatable wheels, the looping means being discontinuously rotatable about a central axis. The central axis of the looping means is offset from and parallel to a plane defined by the plurality of pins secured to either of the wheels about the periphery thereof. The looping means intermittently engage a strand of wire and impart an undulatory configuration thereto.
