Abstract
A spiral pipe machine includes a feeding assembly for continuously feeding a web of material, and a forming assembly for accepting the web. The forming assembly bends the web to form a first section of a spiral pipe having a first predetermined diameter. A controller is employed for selectively instructing the forming means to change its configuration so as to give a second section of the spiral pipe a second predetermined diameter. The controller is capable of controlling the forming station to transition from the first predetermined diameter to the second predetermined diameter during the continuous feeding of the web.
