  • Patent number: 5509965
    Abstract: A preform transfer and coating apparatus and method is provided which utilizes a carrier plate to receive a newly-molded batch of preforms from the molding apparatus preform handling plate. A transfer apparatus automatically moves the carrier plate from a preform-receiving position to a preform-coating position where the preforms are dipped into a coating liquid, after which the coated preforms are moved transversely back towards a starting position where they are discharged into a gaylord or onto a conveyor which feeds a standard gaylord packaging system. There is also a sample-taking apparatus which removes preforms prior to coating.
