Abstract
A method and apparatus for cutting spiral pipe is disclosed. The pipe cutting apparatus includes a driving mechanism that imparts rotation to a knife located inside the spiral pipe via a drive element, such as a drive shaft. The method includes forming a spiral pipe from a strip of material received at a forming head of a spiral pipe former, engaging a driving mechanism attached to a first knife positioned substantially inside the inner circumference of the pipe forming head to impart rotation to the first knife, and cutting the spiral pipe with the first knife by bringing a second knife positioned substantially outside the outer circumference of the forming head into overlapping contact with the first knife.
