<P>PROBLEM TO BE SOLVED: To provide a sequential press working method which can remarkably reduce material cost. Ž<P>SOLUTION: In a sequential press working method of a flanged cup 1, product blanks 2 and blank carriers 3 are separately manufactured. The blank carrier 3 is intermittently sent along a sequential press working line 5, blank attaching holes 6 are formed at a predetermined pitch and a blank coupling arm 7 is formed on the inner peripheral end surface of the hole 6 (S1). The product blanks 2 supplied along a blank supply line 8 are positioned on the blank attaching holes 6 of the blank carriers 3 (S2), and connected to the blank coupling arm 7 (S3). After that, each press work is applied to the product blanks 2, and the flanged cups 1 are manufactured. Since the material and thickness of each of the blank carriers 3 can be arbitrarily selected without restriction of the product blanks 2, the material cost can be remarkably reduced.
