Machine for assembling automatically the tubes of a shell and tube type heat exchanger having many tubes of uniform length and a plurality of perforated baffle plates through which the tubes pass. A machine is provided having a tube holding fixture mounted on a work table. By means of opposing rods, selected quantities of tubes are transmitted successively from a tube supply to the fixture. Suitable controls are employed to complete one full tubular assembly during each operative cycle of the machine. The tubes are transmitted and assembled in the fixture in a single working plane. Following each deposit of tubes, the fixture is adjusted relative to the working plane preparatory to receiving the next quantity of tubes. |
