Abstract
Pairs of standard plates and special plates are assembled and inserted into a fixture along with side plates and intervening fins at respective assembly stations along a conveyor in accordance with a programmed order of insertion. The fixture separates elements already in place by a variable amount as needed to accommodate the insertion of each additional element. The insertion of fins is coordinated with the manufacture of the fins for direct insertion upon formation.
