Abstract

PURPOSE: To obtain a product inexpensive and of high quality as well as of a unique shape, by setting a lid which has been bent of its rim and drawn between an upper die and a lower die fixed with an urethane rubber die at its surface, and by pressing the side wall of the lid outward by the pressure exerting on the urethane rubber die with a pair of dies mated under pressure to push the lid into the space between the die and the outer surface of the lid.
CONSTITUTION: A lid 12 having been bent of its rim and drawn is set between an upper die 14 and a lower die 16. An urethane rubber die 15 is brought in contact with the inside of the lid 12 and the urethane rubber die 15 is fixed on the lower die 16. Next, the upper die 14 is lowered to press the urethane rubber die 15 which expands outward to form the lid 12 by extending to a space 17 of the upper die 14 and a space 18 of the lower die 16. Then the upper die 14 is lifted to take out the formed lid 12.
