The objective of this study was to develop new forming methods making use of undesirable phenomena caused by bending for aluminum alloy extruded sections. The deformations of the cross section in channel exist inner falling and outer falling. In this report, we examined the effect of forming jig (guide plate and forming die) on deformation of cross section in press bending with inner falling in channel by a finite element method and an experiment. Then, it was clarified that the height of guide plate and the radius of forming die influence the deformation of the cross section.
