Abstract: This relates to a guide for guiding a closure cap onto a container neck finish in a machine for automatically applying closure caps to containers. Most particularly this relates to a guide assembly for closure caps which include a metal shell and a plastic overcap including a tamper indicating band which depends below the metal shell and wherein the closure cap cannot be supported by way of flanges or rails of a track in the normal manner in that the supporting part of the closure cap is subject to deformation and not true and round as in the case of metal closure caps. A lower portion of the conventional track has been replaced by a magnetic cap guide unit which forms an extension of the conventional track and which maintains the position of a closure cap after it has been initially engaged by the neck finish of a container so as to maintain the relationship of the closure cap relative to the container which permits the closure cap being seated square on to the neck finish for final automatic application.
