Abstract
A capper chuck is disclosed for applying a closure cap to a container by conforming an annular skirt on the closure against an external conformation, such as a thread and pilfer ring, on the container. The capper chuck includes a plurality of support arms mounted on a rotatable housing for pivotal movement about pivot axes transverse to the axis of the housing, each support arm having a forming roller rotatably mounted thereon for movement to engage the skirt of the closure upon actuation of the support arms by an axial cam plunger. The forming roller support arms are adapted to accommodate oversize closure caps and containers without damaging the closure caps, containers or forming rollers.
