Abstract
Abstract A method and apparatus are provided for spraying reinforced resinous coating material on a surface. Resin and an accelerator are sprayed from one spray device and resin and catalyst are sprayed from a second spray device, each spray being shaped as a horizontally disposed ellipse, as viewed in cross section. The two sprays are directed in converging paths and a flat spray of reinforcing fibers is directed from above in a converging path with the other two sprays. In a preferred form, the resin and accelerator are mixed upstream of one spray device and the resin and catalyst are mixed in a mixing head adjacent the other spray device.
