Abstract

The present invention relates to an apparatus for bending a strip material (100) such as a band blade. A
stationary die (1) having a slit (11) through which the strip material (100) is passed is integrated with a shaft body (3). A movable die (2) which cooperates with the stationary die (1) to bend the strip material (100) is formed into a cylindrical shape. The rotation is transmitted from an electric motor (5), only to one end of the movable die (2). The replacement of the stationary die (1) is facilitated by attaching the lower end of the shaft body (3) by mounting bolts (85) to a machine base (4) through a mounting member (3). When the stationary die (1) is to be replaced, the mounting bolts (85) are removed, the shaft body (3) and the mounting member (8) are pulled out to the lower side of the machine base (4), 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.
