ABSTRACT:
A method for compressively forming a ferrule about a cord is provided. The method utilizes two successive compressive forming steps. In the first step, the starting ferrule is formed into a crescent-like configuration in side elevation. In the second step, the crescent-like configuration is formed into a cardioid-like configuration in side elevation. The method can be practiced using a hand-operated forceps that is equipped with shaping dies. The resulting so formed ferrule displays superior cord holding and retaining characteristics.
