ABSTRACT:
A method and apparatus for the on-demand seating of a lid on pre-formed containers that are carried on a continually moving conveyor. A lid press plate (20) is connected to a linear actuator (36) by a mounting assembly (17). The mounting assembly (17) transmits a seating force from the linear actuator (36) to the lid press plate (20) for seating the lid while simultaneously allowing the horizontal movement of the lid press plate (20) from a first position to a second position by a driving force resulting solely from the application of a seating pressure between the lid press plate (20) and the lid (46). The lid press plate moves at the same velocity as the pre-formed container during application of the seating pressure. The lid press plate (20) is returned to the first position by a biasing assembly (18), after removal of the seating pressure.
