Abstract

PURPOSE: To high accurately form the various kinds of the double fold at the edge of the metallic sheet, by changing over the stationary double-folding jig to be set in the folding apparatus, through a simple operation.
CONSTITUTION: After locating the metallic sheet P on the stationary jig 3a so as to project the necessary length of the metallic sheet P out of the jig 3a, the movable double-folding dies 17, 24, are moved together with the bending bar 37. Hereupon, by the work of the change-over device for the fulcrum 38, the adjusting ridge 28 of the die 17 is brought to the position of the folding ridge 15a; under this condition, the pressure pad 23 of the first die 17 is adjusted to the first folding ridge 13 of the first stationary double-folding die. Then, an edge of the sheet P is pressed tight to the folding ridge 13a by the pad 23; hereby, the first step of the folding work is applied to the sheet P. Next, the sheet P under this condition is folded at the second folding ridge 15a by the pressing plane 25 of the second die 24 for turning the sheet P in the arrowed direction, and hereby, the sheet P is pressed to the second inclined plane 16. As a reslut, a kind of double-folding for an edge of the sheet P is complated.
