ABSTRACT:
An adhesive or sealant is applied to a product by receiving and maintaining the adhesive in liquid form, distributing it to form a film of the material over a predetermined exposed surface area and moving the product relative to the surface area to transfer the material to the product. This is accomplished by use of a housing in which is defined an outwardly opening cavity. A port in the housing admits the liquid material into the cavity. A pad of porous open-cell metal foam covers the opening, with the density of the foam being selected relative to the viscosity parameters of the adhesive to wick or ooze the adhesive from the cavity through the foam and present a film of the adhesive over the outwardly facing surface of the pad. A screen may be disposed over the outwardly facing surface of the pad.
