Abstract

Proposed an edge bending method in which bending of widthwise edges Sc and Sd of a steel plate S is performed several times by a pair of dies 23 and 24 while the steel plate S is intermittently conveyed by a conveyance mechanism 21 such that the widthwise edges Sc and Sd of the steel plate S are subjected to edge bending across an entire length. The lower die 24 that contacts a surface positioned at the outer side of edge bending of the widthwise edges Sc and Sd of the steel plate S to be bent between the pair of dies 23 and 24 has a flat part 24a that contacts the surface positioned at the outer side of edge bending, and edge bending is performed on the widthwise edges Sc and Sd of the steel plate S with a center C1 of the flat part 24a in the conveyance direction 1 being displaced to a delivery side 3 in the conveyance direction 1 relative to a center C2 of the pressing force P generated by the actuator in the conveyance direction 1.
