Abstract
PURPOSE: To prevent generation of the defectively formed product and the qualitative irregularity, by arranging the leveling roller and the guide roller in the early stage.
CONSTITUTION: The vertical position of the hoop 1 is suitably set by the roller of the leveling roller stand for adjusting the vertical position; and the transverse offset and eccentricity of the hoop 1 are corrected by two couples of rollers 3', 3", of the next horizontal position adjusting guide roller stand 3; and then, the hoop 1 is fed in the correct position through next and following stages till the final stage. After that, the hoop 1 is passed through next forming roller stands 4, 5, 6, and is formed into the specified shape. Following to the forming roller stand 6 at the final stage, the hoop 1 is fed to the correcting roller stand 7 for correcting the camber of the formed plane, the residual strain, etc. As a result, the formed product free from the qualitative irregularity, the strain, etc., can be manufactured.
