ABSTRACT:
A method and apparatus for applying threaded plastic closures to the necks of containers wherein the containers are moved successively in an upright position and threaded plastic caps are successively applied in loose engagement with the neck of the container and wherein successive independent hold-down forces are provided by independently mounted plates in overlying relation to the path of the containers being transferred to the capping machine and substantially simultaneously a friction force is applied to the sides of the threaded closures by a spring preloaded rail while the successive hold-down forces are applied to rotate the closures and partially thread the closure on the neck of the containers.
