Apparatus for bending a strip material

An apparatus for bending a strip material, comprising:

• a stationary die having a slit through which a strip material is passed, said slit defining a pair of spaced apart outlet corners and said stationary die being disposed on a shaft body;
• a cylindrically shaped movable die which is moved a predetermined amount when feeding of the strip material passed through said slit of said stationary die is halted, the strip material passed through said slit of said stationary die being pressed by said movable die against an outlet corner of said slit, whereby the strip material is bent by a fixed angle;
• and
• a rotation transmission mechanism connected to said movable die for transmitting a rotation force to said movable die to move said movable die in a forward or reverse direction relative to said stationary die,
• wherein said movable die includes at a predetermined position along its circumferential direction a pair of pressing die portions which oppose each other in the circumferential direction, and an opening for introducing the strip material at a position opposite to said pressing die portions, said cylindrical movable die is rotatably fitted about said stationary die, an opening between said pair of pressing die portions corresponding to an outlet of said slit of said stationary die so that the strip material passed through said outlet of said slit of said stationary die is passed between said pair of pressing die portions, said opening for introducing the strip material corresponding to an inlet of said slit of said stationary die so that the strip material is guided to said inlet of said slit of said stationary die.
