Abstract: The present invention relates to an apparatus for bending a strip material such as a band blade. A stationary die having a slit through which the strip material is passed is integrated with a shaft body. A movable die which cooperates with the stationary die to bend the strip material is formed into a cylindrical shape. The rotation is transmitted from an electric motor, only to one end of the movable die. The replacement of the stationary die is facilitated by attaching the lower end of the shaft body by mounting bolts to a machine base through a mounting member. When the stationary die is to be replaced, the mounting bolts are removed, the shaft body and the mounting member are pulled out to the lower side of the machine base, and another shaft body is inserted from the lower side of the machine base, and the mounting member is fixed to the machine base by using the mounting bolts.

The fixed block has at least one passageway through it extending to the rotary shaft, and the rotary shaft has at least one annular groove in registration with the fixed block passageway and at least one axially extending passageway in communication with the annular groove. As a result, the axial passageway is in communication with the fixed block passageway independently of the angular position of the rotary shaft relative to the fixed block.
