Abstract:
A method of applying a spray-applied foam substance layer upon a structural surface, comprising the steps of:continuously applying said foam substance in liquid form in adjacent axially extending bands of said liquid foam substance to form a coating of a resultant solid layer of said substance, from a spray applicator source moving on a track in alternate directions transverse to an axially extending direction of each band, each said band having a predetermined width and axially extending length;subjecting said spray applicator source to an arcuate uphill movement by the bending of said track away from said surface at each end portion of each said transverse movement of said spray applicator source, wherein said transverse movement of said spray applicator source accelerates in speed along said track;said spray application source being tilted outward by said track as said spray applicator source moves uphill, thereby reducing the amount of said substance in liquid form being applied to the respective edge portions of each said band upon the structural surface.
