ABSTRACT:
The method and apparatus for rolling a section of metal plate into a cylindrical pipe section wherein leading and trailing edges of said plate section are pre-crimped to the final desired radius of said cylindrical pipe section, feeding the leading edge of said plate section into a forming mill that includes an overhead mandrel having a radius approximating said final desired radius of said pipe section, forcing said mandrel to deflect along the length thereof during the forming of said plate section between said mandrel and a pair of driven bending roll means whereby said mandrel and said bending roll means are maintained at the same curvature throughout the length thereof and said plate section is uniformly bent along the length thereof to said desired final radius.
