Abstract: An electrocoating machine for easy-open can ends has an electrocoating wheel rotatable about a horizontal axis and partially submersed in a bath of electrocoating solution. The electrocoating wheel carries ends into and through the bath. A transfer turret and elevator convey coated ends from the electrocoating wheel to a rinse wheel. The rinse wheel surrounds the electrocoating wheel and is mounted for rotation about a vertical axis. The rinse wheel is disposed in a tub which contains a plurality of nozzles for spraying rinse solution on the ends carried by the rinse wheel.

Abstract: A punch press has first and second sets of tooling mounted longitudinally of a press conveyor belt. The second set of tooling is located externally of the usual press columns. A second ram slidably mounted on the outside of the columns is driven by a connecting arm eccentrically mounted on a crankshaft extension. The second ram drives the upper tooling of the second tooling set in a reciprocating manner. The second ram can be operated out of phase with the main ram to reduce the total tonnage required of the press.

Abstract: An injection molding apparatus for forming a molded sealing ring along a peripheral region of a disk-shaped closure insert for a container. Each cavity of a plural cavity injection mold is formed to receive a disk-shaped insert to which a sealing ring is to be molded. Detection means is provided to sense the number of inserts missing from the mold, and a spring loaded pin is operative automatically to close the corresponding gate for each cavity from which an insert is missing. The detection means is operable to signal a molding compound supply means to inject into the mold only that volume of compound required for a cavity or cavities in which an insert or inserts are present.
