ABSTRACT:
A machine with counter-rotating rotors moves heat exchanger plates two at a time with vacuum assist through paths which converge in a vertical mating plane. Arcuate guides engage the plate ends to control the plate path. The rotors are servomotor controlled to synchronously index the rotor in increments separated by dwell periods. After assembly the merged pairs drop between spaced guides into an assembly fixture. At a subsequent brazing operation each plate pair becomes a tube for carrying refrigerant.
