PURPOSE: An apparatus and method for preventing a step of a T-shaped seed are provided to reduce operation time by simultaneously fixing a plurality of main materials and sub materials after the main materials and the sub materials are alternatively arranged. CONSTITUTION: A jig receives a plurality of main materials (400) and sub materials (500) and simultaneously fixes the main materials and the sub materials. The jig includes a bottom plate (210), a front plate (220), a rear plate (230), a front and rear pressing unit (250), and a right and left pressing unit (260). The front plate and the rear plate are separated in parallel and are fixed to the bottom plate. The front and rear pressing unit presses the main materials inserted between the sub materials. The right and left pressing unit presses the main materials and the sub materials. A polisher improves flatness by polishing one side of the main material. |
