ABSTRACT:
Pipe coating apparatus is disclosed. In the preferred and illustrated embodiment, a laterally deployed conveyor belt rotating around a pair of rollers passes beneath the pipe to be coated. Coating material is supplied into a hopper above the belt. The hopper includes positioned slots for receiving reinforcing mesh therein and locates the reinforcing mesh in an extruded ribbon of coating material supported by the conveyor belt and applied to the pipe in helical turns. The application of multiple turns of reinforcing mesh plus shaping of the extruded ribbon enables a thicker layer of coating material to be applied to the pipe, and it is reinforced with multiple layers of reinforcing mesh wire.
