Abstract

PURPOSE: To prevent the work from slipping and press bend the work accurately by revolving a bending roller to the curve along the contact point of the work and the bending roller.
CONSTITUTION: The center of the guide surface 36 of a fixing guide 32 is not used as a bending center, and the center of a bending roller 38 is positioned on the straight line intersecting orthogonally with a neutral axis at a fixed distance l1 on the neutral axis from the neutral origin N of the bending part 35 of a reinforcing bar 34. If the bending roller 38 is revolved in this position, the contact lengths l2, l3, l4 in a range where a bending angle θ is 0W135° coincide always with the contact length l1 of the case when the bending angle θ is zero, and the contact point C1 is a fixed point, thus the bending in which no slipping occurs is accomplished.
