ABSTRACT:
A method and apparatus for directing a foamed material, such as a foamed binder, across the lateral dimension of a moving surface in a uniform and controlled metered flow. In accordance with the method the foamed material is fed into an interior compartment of an applicator unit and is spread laterally as it moves through the compartment toward a laterally extending metering flow gap. After being laterally spread the foamed material is metered in a uniform, controlled manner across the lateral dimension of the moving surface. The applicator unit of this invention has a housing that includes a body portion and a door portion movable relative to each other to form, in a closed condition, the interior compartment that receives the foamed material. The body portion and door portion also aid in forming the laterally extending metering flow gap in communication with the interior compartment, and a passage extends through a wall of the housing to permit the foamed material to be introduced into the applicator unit.
