A post processing cap applicator for applying a cap to a closure spout after erection, spout attachment, filling and sealing of a carton accommodates custom caps. Cartons are conveyed through the applicator in a first forward direction. A cap supply is configured to dispense caps and to position an edge of a cap in a path defined by movement of the closure spout through the applicator. The closure spout engages the edge of the cap. The applicator includes a rotating, torque-applying element and a drive operably connected to the torque-applying element. The drive is operable in a first direction to tighten the cap onto the spout to a predetermined torque and, once the predetermined torque is reached, to stop tightening the cap. A method for post processing cap application is also disclosed.
An apparatus for rotating a cap relatively to a container. The container moves along a predetermined path at a container speed. The cap has a first and a second cap engagement location. The first and second cap engagement locations are circumferentially spaced apart relative to each other. The apparatus includes a first cap engaging component, the first cap engaging component including a first component cap engaging surface for engaging the cap at the first cap engagement location and applying a first substantially tangential force thereto. The first cap engaging surface moves at a first speed when substantially in register with the first cap engagement location. A second cap engaging component includes a second component cap engaging surface for engaging the cap at the second cap engagement location and applying a second substantially tangential force thereto. The second cap engaging surface moves at a second speed when substantially in register with the second cap engagement location. The first and second cap engaging components are operatively coupled to each other for maintaining substantially constant the sum of the first and second speed.
