ABSTRACT:
An apparatus and method for perforating corrugated plastic pipe from the inside of the pipe to the outside and the pipe produced by the method. The apparatus has a perforating device attached to an elongated support member. Perforations are created by advancing pipe over the perforating device or by advancing the perforating device into the interior of the pipe. Where the pipe is advanced over the perforating device, a carriage, holding the pipe, is riding on a track which guides the pipe into engagement or into cutting or perforating proximity with the perforating device. The perforating device includes a housing holding motors with cutters attached to them. The cutters cut the inner corrugations or the valleys of the pipe as the pipe is passed over the perforating device. Pipe is perforated by advancing it over a perforating device, and curing the pipe from the inner pipe surface to the outer pipe surface. The perforated pipe made using this apparatus and method is distinguishable from similar pipe where the preforations are made from the outside of the pipe to the insided of the pipe.
