... drawing process is similar ( Ref 4 ). In the drawing process, cleaned and coated coils of rod or wire are first placed on a payoff tray, stand, or reel; this permits free unwinding of the stock. The leading end of the rod or wire, after being pointed, is then inserted through the drawing die and seized...
