Abstract
A transformer core manufacturing apparatus for manufacturing an annular transformer core having thin plates formed of magnetic materials laminated includes an uncoiler unit which allows a plurality of uncoilers each having a thin plate magnetic material coiled hoop-like to uncoil the magnetic material, a carrier unit for guiding a plurality of the magnetic materials uncoiled from the plurality of the uncoilers as a single group of magnetic body, a first alignment unit for aligning the carried group of the single magnetic body in a width direction, a cut-off unit for cutting the magnetic body aligned by the first alignment unit in a predetermined dimension, a laminating unit for laminating a plurality of the groups of the magnetic body cut by the cut-off unit, a second alignment unit for aligning the magnetic body laminated on the laminating unit, and a control unit for controlling operations of the above cited units.
