METHOD OF CURTAIN-COATING AN ADHESIVE MATERIAL ON A STRUCTURAL PART

摘要

A method and apparatus for applying an adhesive material onto a heavily contoured surface of a structural part including the step of heating the contoured surface to a predetermined temperature level. The contoured surface is then passed through a vertical continuously falling curtain of adhesive material at a speed to deposit a desired uniform coating on the heated contoured surface. The heated surface causes a substantial portion of the liquid solvent of the adhesive to rapidly vaporize to substantially increase the viscosity of the adhesive.
