ABSTRACT:
A method for the continuous production of exhaust pipes for automotive vehicles comprises the steps of continuously withdrawing an elongated substantially flat metal strip from a coil and subsequently bending and forming the moving strip into a longitudinally slitted tube strand. The opposite faces of the slitted pipe strand are then welded together and subsequently the pipe strand, while still moving, is severed into pipe sections of predetermined length and the pipe sections are then transferred to at least one bending apparatus for bending the pipe sections into exhaust pipes with predetermined bends; and an apparatus for carrying out the above method.
