A method for twisting an elongated cord member to form a permanently twisted cord element is preferably performed utilizing an apparatus which includes first and second end units, first and second securing and twisting assemblies for securing opposite end portions of the cord member to the first end unit and for thereafter axially rotating the opposite end portions of the cord member. The apparatus further includes an intermediate securing assembly on the second end unit for selectively rotatably and non-rotatably securing the cord member to the second end unit at an intermediate point in the cord member. The apparatus operative in the method by securing the opposite end portions of the cord member to the first end unit, securing the cord member to the intermediate securing assembly on the second end unit, axially rotating the opposite end portions of the cord member while maintaining the intermediate point of the cord member in stationary relation and then operating the intermediate securing assembly to allow the intermediate point to rotate so that opposite sections of the cord member are twisted about one another.
