ABSTRACT:
A bending apparatus has a fixed supply head, a movable bending head, a material feeding device, a sliding device, and a swinging device for sliding and swinging the movable bending head. The sliding device and the swinging device slide and swing the movable bending head against the fixed supply head and arrange the movable bending head in an accurate position and angle. The material-feeding device continuously feeds a material through channels of both the fixed supply head and the movable bending head. Because of the swinging ability of the bending apparatus, the material is bent between the heads with accuracy.
