Abstract

PURPOSE:To pass steel bars of various diameters between revolving rolls and straighten these by inclining the axial lines of a pair of rolls whose middle parts are roughly of truncated cone shape at the same angle. CONSTITUTION:Rolls 11, 12 are revolved and a steel bar is revolved in the same direction and is advanced in these two rolls along the specified path. Then, the steel bar receives the stress beyond its plastic limit in both of the neighborhood of bent parts 30 and 32. Since the bent parts 30, 32 are mutually in opposite directions, the steel bar is carried into between the rolls 10, 11 along a horizontal path 21, and is carried out along a horizontal path 22.
