    • A three-roller bending apparatus having a movable top roller and two stationary bottom rollers has a curvature measuring unit for automatically measuring the radius of curvature of a workpiece being bent and for displaying the measured value for an operator. The curvature measuring unit comprises three probes, at least one of which is a movable probe whose displacement produces an electrical output signal while the remaining probes are stationary. The probes are made to contact the surface of a workpiece, and the electrical output signal is applied to a calculating and display unit which calculates the radius of curvature of the workpiece and displays the result. The apparatus may further comprise a CPU which automatically controls both the rolling of the workpiece and the operation of the curvature measuring unit and determines when to terminate rolling based on the output of the curvature measuring unit. The apparatus may also have auxiliary rollers which press the workpiece against the bottom rollers, making it possible for the bottom rollers to move the workpiece even when a gap develops between the workpiece and the top roller.
    • 具有可动顶辊和两个静止下辊的三辊弯曲装置具有用于自动测量被弯曲工件的曲率半径并显示操作者的测量值的曲率测量单元。 曲率测量单元包括三个探头,其中至少一个是可移动探针,其位移产生电输出信号,而其余的探头是静止的。 使探针接触工件的表面,并将电输出信号施加到计算和显示单元,该单元计算工件的曲率半径并显示结果。 该装置还可以包括CPU,其自动控制工件的滚动和曲率测量单元的操作,并且基于曲率测量单元的输出确定何时终止滚动。 该装置还可以具有辅助辊,其将工件压靠在底辊上,使得即使当在工件和顶辊​​之间产生间隙时,底辊也可移动工件。
