ABSTRACT:
An automotive radiator core subassembly including a plurality of individual tubes disposed in uniformly spaced, parallel relationship with the opposite ends of the tubes seated in openings in spaced parallel headers joined into a rectangular peripheral frame by opposed side frame members with fins inserted between adjacent tubes is assembled by apparatus which includes a pair of finger assemblies operating at opposite sides of a support table. The finger assemblies each include a series of vertically disposed fingers interlinking to each other in a horizontally extensible chain. When the chains are extended, tubes are deposited between the fingers which are so spaced as to provide adequate room to deposit the fins between the tubes. Subsequent compression of the finger chains moves the tubes and fins into their final assembled relationship to each other and aligns the tubes with the openings in header members supported on header carriers on the machine frame.
