Abstract
The present invention concerns a device for bending pipes, tubes, bars and rods such as may be used in roof racks, crash bars and in general plumbing. The device includes a frame with an arm extending to both sides, a pair of spaced stop members on the arm, a hydraulic ram fixed to the frame, a link connected to the piston of the ram and a former mounted on the end of the link. The arrangement is such that two or more adjacent bends can be made in a rod or bar so that the bends are in different planes.
