Abstract
Disclosed herein is an assembly for forming a radial end flange upon a length of spirally wound corrugated metal pipe. The assembly includes a head stock having a pair of rotatably driven flanging rollers for preparing the end of the pipe to be flanged and initiating the flange, an ironing wheel mounted perpendicularly with respect to the flanging rollers for completing the flange, and a shearing wheel associated with one of the flanging rollers for removing excess metal from the formed end flange. The assembly also includes a tail stock having upper and lower support rollers for securely supporting the other end of the pipe and a center turntable support for positioning the length of pipe to be flanged.
