The present invention relates to a method of making a trapezoid wire. More particularly, the present invention relates to a method for making a trapeziform trapezoid wire among core wires used for an electric wire. For this, in a method of drawing the linear element of an electric wire by using a drawing apparatus, dices which have various withdrawable holes are respectively arranged between capstan blocks (10). The linear element is drawn by making the linear element pass through various withdrawable holes and making the trapezoid wire at the same time. |
