Abstract: An apparatus for directing and seating a closure having abutments disposed about its interior periphery, with a container having mating grooves for receiving such closure. The preferred embodiment employs an overhead adjustable belt for correctly positioning and guiding the closure onto a moving container by applying a continuous downward force across the top of the closure once it comes to rest upon the container. The container in turn is caused to be contacted at its periphery by a rotating belt and a back-up stationary surface. The resultant torque imparted thereto urges, the container to turn and positively engage and lock with the closure abutments.An alternate embodiment, employs a knurled roller disposed along the container-closure line of travel for initially positioning the closure on the container by engagement with the closure at its periphery. A frictional pawl further upstream, contacts the already positioned closure to cause initial locking between the closure abutments and container grooves.
