Spray coating apparatus
Abstract
Abstract A gun having a center orifice for delivering a course of dry particulate material and plural nozzle tips adjacent the orifice. The nozzle tips are adapted to form flat fanshaped streams of adhesive. Each of a pair of such tips is located in diametric opposition to the other and such nozzle tips are so oriented that the flat fan-shaped streams slice through the course of dry material to spread out the dry material and to coat the dry material with adhesive so that the adhesive will adhere to a surface. A pair of auxiliary nozzle tips are provided in quadrature with the tips previously mentioned and contribute to the shaping of the course of dry material and the application of adhesive to the dry material and to the surface being coated.
