PURPOSE:To feed all works housed in a work housing part to an aftertreatment device at a constant pitch till assemblage of a new work is all over and make them producible, by connecting a complete work temporary housing part to a terminal of a second work conveying passage in an operating line. CONSTITUTION:A printed circuit board is temporarily assembled with electronic parts as being repeatedly conveyed through both first and second work conveying passages 14 and 15 at the specified times. For the duration till the printed circuit board is completed and all parts are housed in a housing part 11, the printed circuit board housed in the work housing part 11 is carried out toward a soldering device 12 at a constant pitch from the work housing part 11 by a constant pitch delivery device 19. Electronic parts are soldered with this soldering device 12 and locked to the printed circuit board being so far carried in the soldering device 12 at a constant pitch from this work housing part 11, making up a printed circuit body. When printed circuit boards inside the work housing part 11 are all carried out, a new printed circuit board is carried in from the operating line 10.
