by Finger Rotation and Finger Arm Rotation , the wire loading process the unloading process and the bending process have a simple structure composed of a complex with a single Finger Clamping the middle area of wire by Finger prevents deflection and deformation possibility and available process range is extended to an elongated wire of at least 2.0mm The pipe bending quality is excellent by bending process based on bead position of pipes with bead detector
