Description of the Related Art For example, in the case of a copper plate for a roof, a rectangular copper plate is formed on each side end thereof with a gouge which is bent to a predetermined width in advance, and the copper plates with the goby are sequentially joined by vertically folding the goby for roofing. However, in order to prevent rainwater from penetrating from the vertically folded portions of these goby due to the capillary phenomenon, the upper and lower goby to be folded must have a longer width of the lower gob than the upper gob (for example, the upper gob). (Goby 14 mm, lower goby 16 mm).

Conventionally, as a goby folding device for a copper plate for a roof,
As shown in FIG. 6, a bending plate (b) is rotatably connected to one end of the surface plate (a) via a hinge (c) so that the upper surface of the surface can be superimposed on the surface of the surface plate (a). A holding plate (e) is fastened with a thumbscrew (f) with a spacer plate (d) having a long hole interposed between the bending plate (b) and the bending plate (b) and the holding plate (e). ), A bent groove (g) having a depth corresponding to the width of the goby to be bent is formed.
