PROBLEM TO BE SOLVED: To automatically improve fitting failure of a die D by executing the retry operation of the die D when the fitting failure is caused in the die D. SOLUTION: When a detection signal from an upper detection sensor 61 and a lower detection sensor 63 is not input even when the predetermined time is elapsed after starting the descent of an upper pusher 59 and a lower pusher 49, the pushing pressure by the lower pusher 49 is increased until the detection signal from a sub lower detection sensor 65 is input, an upper pusher 59 and the lower pusher 49 are once elevated, and the upper pusher 59 and the lower pusher 49 are again lowered until the detection signals from the upper detection sensor 61 and the lower detection sensor 63 are input.
