Abstract
Pipe coating apparatus which incorporates means for rotating and advancing a pipe along a specified path and an applicator means for placing cementicious materials thereon. The slurry is applied by a mechanism having a top opening which receives cement therein, the opening directing cement to a reinforcing ply which is applied to the pipe. The reinforcing material is delivered through the applicator mechanism. The cement falls on the reinforcing material which normally has a mesh construction. The pipe is advanced and rotated simultaneously. The helical movement of the pipe draws the reinforcing mesh into a gap at the lower side of the pipe above a free rotating parallel roller. A ply of weatherproofing material such as plastic film is placed on the pipe.
