Abstract: A transfer mechanism places one part in a fixture on a continuously rotating table and substantially simultaneously picks up another part from an adjacent fixture on the table. The transfer mechanism then places the picked-up part on one fixture of an intermittently rotatable table while substantially simultaneously picking up another part on the latter table preparatory to placing that part on the continuously rotating table. A turn over mechanism subsequently picks up the part placed on the intermittently rotatable table by the transfer mechanism, turns the part over, and replaces the part on the intermittently rotatable table preparatory to the part being picked up from the latter table and returned to the continuously rotating table by the transfer mechanism.
