A METHOD FOR FORMING A PLURALITY OF THREADING WIRES, EACH HAVING A STIFFENED END PORTION, FROM A SUPPLY OF AN INSULATIVELY COATED FINE FLEXIBLE WIRE WHEREBY EACH INDIVIDUAL THREADING WIRE LENGTH IS ADEQUATE FOR THREADING A SELECTED SERIES OF APERTURED ARTICLES AND EACH SAID STIFFENED END PORTION FACILITATES THE THREADING OF SAID ARTICLES, WHICH METHOD COMPRISES THE STEPS OF: (A) WINDING ON A FRAME PLURALITY OF SPACED TURNS OF AN INSULATIVELY COATED FINE FLEXIBLE WIRE SUCH THAT EACH TURN OF THE WIRE DISPOSES A PORTION THEREOF INTENDED TO BE STIFFENED IN A SUBSTANTIALLY STRAIGHT LINE; (B) SECURING THE WIRE TO THE FRAME; (C) REMOVING THE INSULATION FROM THE PORTIONS OF THE WIRE TURNS INTENDED TO BE STIFFENED; (D) APPLYING A COATING OF METAL ONTO THE INSULATION REMOVED PORTIONS OF THE WIRE, THE APPLIED COATING BEING INTEGRAL WITH THE WIRE AND OF SUFFICIENT THICKNESS TO CAUSE THE METAL COATED PORTIONS OF THE WIRE TO SUBSTANTIALLY STIFFEN; (E) CUTTING SAID TURNS AT THE SAID STIFFENED PORTIONS TO REMOVE THE TURNS FROM THE FRAME AND THEREBY PROVIDE A PLURALITY OF INDIVIDUAL THREADING WIRES EACH HAVING A STIFFENED STRAIGHT END PORTION.
