Abstract
A bending processor for a pipe has a pipe bending unit and a pipe twisting unit. The pipe bending unit is rotated by a predetermined angle while pressing the processed pipe against the circumferential face of a bending die, and performs the bending processing. The pipe bending unit may be movable in the longitudinal direction of the processed pipe or may be fixed. The pipe twisting unit is freely rotated by a predetermined angle with the center of the processed pipe as an axis. The pipe bending unit has a tensile bending function and a compression bending function.
