PROBLEM TO BE SOLVED: To simplify the work in association with the opening and closing operation of a die, and to extend the operation time of a die device. SOLUTION: A die on-off apparatus is constituted of an apparatus main body and a plurality of die main bodies and has a die 24 wherein a manifold 33 and a slit 34 are formed between the die main bodies and an on-off mechanism 25 moving at least one of the die main bodies to the other one of them to selectively set the die 24 to a closing position and an open position. In this case, since the die 24 can be opened without being detached from the apparatus main body and it is unnecessary to delicately adjust the position of the die 24 after the die 24 is again closed, the work accompanied by the opening and closing of the die 24 can be simplified and the operation time of the die on-off apparatus can be extended.
