The basic principles of the cold roll forming process is: Plate bending in a straight line along the longitudinal line. However, with residual pressure and plate produced

in the process of bending deformation in the stress combination, always cold strip deviation equipment. Describe the strip from the last roll out after the departure degree,

the most common used words such as :side bending-horizontal bending, warping-vertical bending, twisting-spiral shape. The end of cold roll forming machine using the 

straightening mechanism can solve this problem.

The basic principles of straightening mechanism, Profile with side bend, warp and other defects, the leveling mechanism along the opposite direction have the top enough 

pressure, to cause permanent distortion. If the deformation in the opposite direction is ok, then after rebound,the roll can be totally leveled. If the forming profiles distort in

some direction, the leveling machine is rotated in the opposite direction, then produce permanent plastic deformation. If the rotation angle is right,after rebound, profiles 

will no longer be reversed.

To bend or twist, usually processing between the last forming roller and the cutting die. If the last roll can not effectively support the profile, when into the one side of the 

leveling machine, have to support the whole profile section. When level the asymmetric profile, maybe distorted when leveling, at this time, have to bend, distort and level at 

the direction of profile distortion. In the process of leveling, the profile will move up and down, right and left. So the gap between leveling machine and profile need looser. 

There is a certain gap between the profile surface and leveling mechanism

The leveling machine usually use Turkey level head.
