Adhesive applicator device

摘要

There is disclosed a device for applying a liquid adhesive onto the surface of bottles moving in upright seriatim fashion on a horizontal moving conveyor at an adhesive applying station. The device includes a container for liquid adhesive and a pivoted frame supported over the container which supports a beveled feed wheel on an inclined shaft driven by its connection to an electric motor. The beveled feed wheel rotates partly submersed in the adhesive and engages a cylindrical applicator roller freely rotatable on a vertical axis at the applying station. The outer periphery of the roller is comprised of a porous, resilient layer, e.g. a spongy urethane layer which receives adhesive from the beveled facing of the feed wheel. The beveled facing of the latter is non-porous and smooth, e.g. a steel facing. The roller is properly loaded with adhesive transferred by the feed wheel and is also driven by the wheel in a direction corresponding with movement of the bottles in the applying station; whereat the roller surface layer engages the bottle surface and applies adhesive thereto.
