ABSTRACT:
Two dies, each having a blade and a bending block with a specified gap therebetween, are disposed in vertical alignment with and in opposing relationship with each other in such a way that the vertical blade center line of one die comes almost at the center between the vertical blade center line of the other die and the end face of the bending block of the latter die facing the blade. Either the blade or the bending block is integrally formed with the die body while the other is securely fixed to the die body by a fastening means.
