Completely automatic system stamps and forms metal discs for closures of the two-piece type and feeds them sealing face down to a conveyor belt. At first transfer zone, magnet pulls each disc or lid up against lower pass of second conveyor belt. Magnetic pulley retains lids in contact with belt to swing up through arc to upper pass of belt. Lids are then conveyed to treating zone where gasket material is applied as lids are rotated and transported arcuately. Radial arms on carousel travel in circle to pick up lids sequentially by magnetism or vacuum from coating table and transfer them to upper pass of next conveyor. At next transfer zone, lids are picked up sequentially by individual magnets on lower pass of next conveyor and moved to next transfer zone where they are released in groups to form transverse rows on wide conveyor belt. Belt passes through curing station and diverter realigns transverse rows to fore and aft single file. Next conveyor transfers and feeds lids sequentially to assembly zone. Closure bands are also fed sequentially to assembly zone and combined with lids to produce assembled two-piece closures. Lids may alternatively be fed to different assembly zone where they are packed in sets for shipping. One-piece closures with integral lid and flange may be formed and processed in same manner.
