ABSTRACT:
An improved apparatus for forming and cutting spirally formed pipe, particularly spiral pipes having a diameter of approximately one inch or less, is disclosed. The device for slitting the spiral pipe into sections includes a first knife that is positioned inside the spiral pipe and a second knife positioned outside of the pipe. A support sleeve is also positioned outside of the pipe and is in a fixed radial position with respect to the pipe. The inner and outer knives and the support sleeve move axially with the pipe as the pipe is severed.
