Abstract
PURPOSE: To make possible the straightening at comparatively good accuracy, by detecting the amount of straightening for the material to be straightened before applying the straightening load, at straightening the material to be straightened, and by measuring the proportional factor of the material to be straightened, after applying a specified load.
CONSTITUTION: The straightening angle of the material to be straightened is 6 degrees, for instance; after releasing the load, a load equivalent to the point C for giving a deformation to the extent unexceedable above started straightening angle 6 degrees is applied to the material to be straightened; and then, the load is temporarily released and again is applied. By this procedure, (variation of deformation/ variation of load = proportional factor of the material to be straightened) can be easily detected for the span C-C' or C'-C. Moreover, by increasing the torque to be applied to the material to be straightened, and by releasing this twisting torque at the point D where (twisting angle - proportional factor × twisting torque) reaches above stated straightening angle, the straightening at high accuracy becomes possible.
