ABSTRACT OF THE DISCLOSURE The present invention relates to an application member for applying a coating material, such as a pressure sensitive adhesive, to a receiving surface, such as a paper substrate. The application member includes a cylindrical peripheral surface and a plurality of spaced, discrete structures projecting from the peripheral surface of the hub, whereby adhesive may be carried on and between the structures prior to being applied to the receiving surface. By varying the surface velocity of the application member relative to the velocity of the substrate, the characteristics of the adhesive layer applied to the substrate may be changed.
