Supporting surface 11 of base film 2
, a presser plate 13 that moves up and down with respect to the support surface 11 by rotation of the handle 12, and a bending presser plate 15 rotatably held by a shaft 14. A pin 16 is provided perpendicularly to the support surface 11. The holding plate 3 has a pointed end 17 for bending the base film 2 extending horizontally at its lower end, and a pin hole 18 in which the pin 16 fits into the pointed end 17.

ピン】６から外す。First, the first step is to form a pin hole in the base film 2.
As shown in Figure A, the base film 2 is passed through a plate bending machine 10.
Place it on the support surface ll of the base film and fit the pin hole of the base film to the pin 16 of the support surface 11 to position it. Next, lower the holding plate 13, fit the pin hole 18 with the pin 16, 0 and 1B to press and fix film 2
As shown in the figure, the one-bending presser plate 15 is rotated upward, the base film 2 is bent at its end face 19, and is pressed against the upper surface of the pointed end 17 of the presser plate 13. In this state, hot air is blown onto the bent portion 3 of the base film 2 to plastically deform it. The means for blowing hot air is not particularly limited and is arbitrary, but a commercially available hair dryer can be suitably used. After that, the first bending press plate 15 is rotated downward and returned to its original position, the temporary presser plate 13 is raised, and the base film 2 is removed from the pin 6.
以上で１回の曲げ加工動作が終了する。With this, one bending operation is completed.

がり部を形成することができ。Effects of the Invention As described above, in the bending method of the present invention, the base film is positioned with pins and bent by the 5-plate bending machine, so the base film is fixed at an extremely accurate position and bent at an accurate position. Moreover, since it is plastically deformed with hot air after being bent, it can be bent at an acute angle, and it will hardly recover its original shape even after being removed from the plate bending machine, and the base film will not be damaged in any way during bending. Therefore, the tensile strength does not decrease.According to the present invention, it is possible to form a bent portion with high tensile strength and high precision.
