Abstract
This invention is comprised of a lower die having a groove-like cavity formed at its upper surface; a rotary die supported in the cavity of the lower die at both ends thereof by a shaft and rotatably stored in it; an upper die arranged above the rotary die; and a driving device for rotating said rotary die in a downward direction after the upper die is opened and for retracting it. The cavity is formed with some protrusion steps at its inner circumferential surface for use in supporting the rotary die when pressed. The rotary die is formed with a forming part for gathering and bending a metallic plate at its upper surface to be extended in a longitudinal direction of the rotary die. The gathering and bending blade to be fitted to the forming part of the rotary die is formed at the upper die. In the case of the present invention, the aforesaid rotary die is supported at the protrusion steps when pressed while the outer edge of the forming part is being abutted against the upper edge of the lower die and after pressing operation, it is rotated in a downward direction by the driving device.
