【Example】

FIGS. 1 to 3 show an embodiment of a patrone production system according to the present invention. FIGS. 1 (A) to (D) and (a) to (d) show blanks cut to predetermined dimensions. FIG. 2 is a schematic side view showing a body plate forming machine and a telemping ribbon sticking machine incorporating the process shown in FIG. 1, and FIG. FIG. 3 is a schematic front view of a forming device incorporated in a boat-shaped bending step in the body plate forming machine of FIG. 2. In each of the drawings, reference numeral 1 denotes a blank. The blank 1 is obtained by cutting a large plate made of a patrone body plate material into small plates by a steel plate slitter such as a tandem slitter and conveyed to a predetermined position. Things. The rectangular blanks 1 are sucked and held one by one by a suction device 2, and are first sent to a first step called notching by a carrier claw 3, and are punched out as shown in FIGS. 1 (B) and 1 (b). It is formed in a predetermined shape by the processing device 4. The blank 1 is sent to the one-side lip 90 ° bending step as shown in FIGS. 1C and 1C by the carrier claw 3, and the one side 1 a of the blank 1 is turned by the one-side lip 90 ° bending device 6 in FIG. )
It is bent 90 ° as shown in the figure. Then, the blank 1 is processed by the boat-shaped bending device 7 into a shape as shown in FIGS. By the way, in the steps shown in FIGS. 1 (B) to (D), the blank 1 has the outer design surface 1b facing upward (the punching device 4 and the one-side lip 90 ° bending device 6 side). Various operations (notching, one-side lip 90 ° bending, boat-shaped bending) are performed by the carrier nail 3 while the outer design surface 1b of the blank 1 is facing upward. That is, when the forming process is performed as described above, that is, when the forming process of the blank 1 is performed with the design surface 1b facing upward,
For example, in the boat bending process, as shown in FIG.
Processing can be performed while supporting the central flat portion 1c of the blank 1 with a large area by the lower mold 7a of the boat-shaped bending device 7, so that the posture is stable and jamming hardly occurs.
