An apparatus for supplying an adhesive to a cylindrical drum rotatable about a vertical axis for applying the adhesive to labels, which comprises a housing disposed in close contact with the drum and having a curved wall extending parallel and adjacent to the circumference of the drum. First and second compartments are defined in the housing, juxtaposed downstream and upstream with respect to the direction of rotation of the drum, and exposed to the drum through openings in the curved wall. Also an upper compartment is defined in the housing over the first and second compartments. A passage communicates the upper compartment to the first compartment, and drain pipes communicate the first and second compartments to the upper compartment. The intersections between the downstream side walls of the first and second compartments and the curved wall form vertically extending scraping edges, and the drain pipes are substantially aligned with the scraping edges. |
