Abstract
A method of (and apparatus for) applying and adhering an adhesive-backed label to the surface of a material (e.g., the butt end of a board) in the presence of a contaminant (e.g., sap) that neutralizes the adhesive forces of the adhesive. The method includes the serial steps of applying a surface preparation layer or substance (e.g., a hot-melt adhesive) to the material, the layer (or substance) being compatible with the material to be labeled and the adhesive of the label and being further capable of displacing the contaminant in such a way as to restore the adhesive force between the label adhesive and the material to be labeled; and, immediately thereafter, applying the adhesive surface of an adhesive backed label to the surface thus prepared, that is, onto the surface preparation layer.
