Abstract
An apparatus and method for applying adhesive to the open ends of containers having oppositely disposed front and rear wall panels, oppositely disposed side panels, and a center line parallel to the front and rear wall panels and aligned with the center of the side wall panels. The apparatus includes a conveyor for moving the containers along a line of movement through an adhesive application area. The containers are substantially immovably supported during adhesive application procedures. A pair of rotary adhesive applicators apply adhesive to the edges and portions adjacent such edges of an open end of the containers. These rotary adhesive applicators each have a central axis which is oriented in a non-normal relationship to at least one of the center line and line of movement of such containers, and are arranged relative to the conveyor such that as the containers pass the applicators, such applicators contact the edges of an open end of the container panels. A relative speed differential is maintained between the containers being moved along the conveyor and the rotating adhesive applicators. This differential causes a predetermined amount of adhesive to be deposited on the ope…
