Abstract

An apparatus to apply uniform amounts of adhesive to containers at a high rate of speed. Containers are selected at a variable interval. The containers are positioned against dual spiral timing screws (one timing screw above the other). Turning the timing screws a constant (but adjustable) number of degrees with respect to each other while they rotate at the same speed will either advance a container in a level position or they may be advanced while tilted, forward or backward depending upon the relative position of the upper and lower timing screw. While the container is advancing, it is also being turned so that the upper surfaces of the container may be positioned against a rotating cylinder to which a layer of adhesive is continuously applied. In this manner adhesive may be applied around the entire circumference of a container on the top, inside edge, outside edge or both edges.
