ABSTRACT OF THE DISCLOSURE There is provided an apparatus and method for applying adhesive to the open ends of containers each having a non-cylindrical cross-section, 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 conveying means for moving the containers along a line of movement through an adhesive application area. The conveying means includes attachment means for substantially immovably supporting the containers thereon at least during adhesive application proce- dures. The adhesive application area includes a pair of rotary adhesive applicators for applying 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 conveying means such that as the con- tainers pass the applicators, such applicators contact the edges of an open end of the container panels. Rotation control means maintain a relative speed differential between the containers being moved along the conveying means and the rotating adhesive applicators. This relative speed differential causes a predeterm- ined amount of adhesive to be deposited on the open edges and portions adjacent the edges of the wall panels when the rotating adhesive applicators contact such open edges of the container panels. This simple apparatus and method can effectively and efficiently apply a predetermined bead of adhesive to the open ends of non-cylindrical containers on high speed automatic equip- ment.
