ABSTRACT:
A method of applying various kinds of bending working accurately to a metal tube of a small diameter to be worked, which comprises seizing one end of a metal tube to be worked and setting a working direction, transferring the tube to a working position, applying predetermined bending by paired roller means, transferring the same to the succeeding step and applying the same working. Such operations are repeated as required. The apparatus employed for practicing the method comprises a chuck, a receiving roller and a bending roller and a control means for controlling the operation of them. Various kinds of bending working can be applied efficiently and accurately to a metal tube of a small diameter to be worked by a simple method and with an apparatus of a simple structure.
