Abstract
An apparatus for manufacturing an iron core comprising: a plate thickness measurement unit for measuring a thickness of the strip as an intermediate product of the iron core; an inlet guide for positioning the strip in a widthwise direction thereof; a mil roll unit for performing a rolling-bending process to the strip fed out of the inlet guide; a restraint jig for shaping the strip fed out of the mil unit and holding a curvature thereof constant; and a curvature measurement unit for measuring a curvature of the strip to which the rolling-bending process has been performed by using said mill roll. Position control of the inlet guide, the pressure roll unit, and the restraint jig is performed based on at least one of the plate thickness and the curvature of the strip.
