[Also in Division F4] In a method of making a finned tubular radiator a stack of plates 3 each having apertures aligned to define a tubular passage are slid over a metal separator strip 6 and clamped in stacked relationship via two tightening members, e.g. of the alternative types indicated at 7 and 8, secured to each end 9 and 10 of the strip 6. End pieces or pipes 22 positioned current after the main clutch is engaged being sufficiently low to allow the press motor 28 to provide a press acceleration related to that rate of increase. As shown, radiator grills are fed from an endless conveyer 31 by transfer arms 37 to upper and lower dies 26, 27 associated with a reciprocating slide 25. Second transfer arms 33 then remove the grills W from the dies to the next conveyer 34. The motor 28 drives the press, the transfer arms, and the conveyers through a belt (42), Fig. 2 (not shown), and layshaft gearing (51)-(56). at the ends of the radiator passage may be incorporated within the construction. The complete assembly including the separator strip is then secured together by cementing, welding or brazing. The tightening member 7 has a screw-threaded rod 11 secured to the separator 6 through bolts 13; an annular member 14 may be tightened against the end radiator plate (as shown), or an end piece 22 if included, via a nut 15. An alternative kind of tightening member 8 which may be employed, comprises self-tightening jaws 18 engaging the end of the metal strip, a handle 21 and an annular clamping member 20 bearing against the end radiator plate.
