Abstract: The mathematical description of a butterfly section shoulder is presented and the equations of the bending curve, the shoulder curved surface and the fringe curve are developed. To confirm the validity of the mathematical description, a 3-D shoulder is modeled on computer, and an actual shoulder is manufactured by rapid manufacturing machine, and a practical shoulder is made by traditional method with steel sheet. The result established theoretical basis for making ‘self-standing bag of four edges’ on the ‘form, fill and seal’ machines.
