BENDING APPARATUS ABSTRACT OF THE DISCLOSURE A bending template assembly is attached to a main shaft mounted in an elongated bed and is provided with a plurality of bending templates put in layers in the axial direction of the main shaft. A long work is held, at the rear end thereof, in a chuck mounted on a carriage for work slidable in the longitudinal direction of the work. The chuck is movable transversely to the work, i. e., horizontally and vertically and the work can be located against the outer periphery of desired one of the plural bending templates by the horizontal and vertical displacement of the chuck. A fastening apparatus provided with fastening pieces of the number equal to that of the bending templates is disposed on a bending arm mounted on the main shaft at one end thereof. This fastening apparatus is not only rotatable together with the bending arm but also movable horizontally and vertically relative to the bending arm and can be approached or retreated from the bending template assembly. When the fas- tening apparatus is retreated the choice of bending templates by the carriage for work is carried out. When the fastening apparatus is approached to the bending template assembly the work is held between one of the bending templates and corresponding one of the fastening pieces and the bending arm is turned to form bends on the work.
