APPARATUS POR COAnNG...nNIRSU.S. Patent 5,875,538. Mar. 2, 1999FA Kish et al., assignors to IllinoisTool Works Inc., Glenview, Ill.

A method of providing a strip ofcoated fasteners comprising pro­viding a plurality of metal wirespositioned substantially in paral­lel engagement with each other;electrostatically covering the ex­terior surfaces of each wire with amaterial composed substantiallyof solid particles; removing anyexcess material from desired por­tions of the wires; curing the ma­terial, thereby causing the solidparticles to adhere to one anotherand to the wires, such that thewires become adhered to one an­other and form a continuous bandof parallel wires; cooling the coat­ing material after the curing step,thereby forming a coating havingvoids therein such that a shearstrength of the coating is lessthan a shear strength that wouldhave resulted from the particlesadhering together and forming a

coating having no voids therein;and forming the band of parallelwires into fastener strips.
