ABSTRACT:
An adhesive viscous liquid screed for dispensing a uniform thickness of an initially viscous liquid material onto a planar work surface in order to produce a film of predetermined thickness, length and width. The screed engages a planar horizontal application surface and a reservoir is filled with a liquid adhesive. As the screed is propelled forward along the application surface, the pressure on the adhesive due to gravity causes it to be forced out of the reservoir and through a first release orifice, thereby depositing a thin film of liquid adhesive. The height of the film is determined by the distance between the application surface and the bottom surface of a rib defining the release orifice and the width of the film is determined by the distance between the substantially vertical sides of the first release orifice.
