US 5,468,293 A · Apparatus and method for constructing a spray in place structure

Abstract

A system for cutting and spraying a plurality of resin strands with an emulsion. The system includes a spray gun that has a cutter assembly that cuts a single resin thread into a plurality of individual strands. The cutter assembly is constructed to cut the strands into varying lengths. The strands are blown from the gun by a housing that is connected to a source of pressurized air. The housing has a pair of openings that are adapted to blow the strands parallel with the gun, so that the resin lies flat on the working surface. The gun also has a pair of nozzles attached to the housing and coupled to a progressive cavity pump that supplies an emulsion. The nozzles are adapted to spray the emulsion into the path of the resin spray, so that the resin and emulsion are mixed onto the working surface.
