ABSTRACT This design is about the machine that stents roll forming repair U shaped steel. paring various principles, I finally determination using the side roller swing four roll bending forming principle. In the design , I did a detailed calculation for the roller gears. First of all,pared various principles of roll bending and selected the types, then I design the mainly analyzes main and vice roller. Side roller swing four rolls bending forming principle by lord to roll. Vice roller to roll bending U sections provide motivation for continuous rolling, curved, economic efficiency. The last part of the paper is about decelerator which is choosing triple expanding column gear const r uction. The material of gear is 40Cr ( hardening ) .The gears , axes , bearings are checked , so to confirm this design this design is practical.
