ABSTRACT An apparatus for forming and slitting spirally formed pipe, particularly spiral pipes having a diameter of approximately one inch or less, is disclosed. The pipe forming apparatus includes an enclosed forming head and a mandrel. A continuous strip of metal is driven around the mandrel and inside a lateral bore in the forming head in a helical manner. First and second rollers mounted in the forming head partially form a spiral lockseam. A third roller mounted in the upper portion of the forming head closes the spiral lockseam. The mandrel is both rotatable and pivotable. The device for slitting the spiral pipe into sections includes a first knife that is positioned inside the spiral pipe. This knife is mounted at the end of a rotatable boom, that extends through the mandrel and is positioned inside of the spiral pipe. A second rotatable knife is positioned outside of the pipe. A rotatable support roller is also positioned outside of the pipe, and opposite the outer knife. To cut the pipe, the outer knife punctures the pipe and overlaps the inner knife, and the support roller abuts the opposite side of the pipe. The inner and outer knives and the support roller move axially with the pipe. As the pipe con- tinues to rotate, it is completely severed.
