PURPOSE:To satisfactorily polish-finish a plate-shaped small piece without scattering an abrasive sprayed to the plate-shaped small piece by providing a polishing section which presses a belt-shaped polisher delivered in the transfer path of a transfer section to the other plane of the plate-shaped small piece and polishes the other plane via the rotary vibration. CONSTITUTION:A plate-shaped small piece 2 fed on a belt-shaped adhesive body 4 is transferred while its one plane is stuck to an adhesive layer provided on one face of the adhesive body 4. The belt-shaped polisher 8 of a polishing section C delivered to face the other plane of the plate-shaped small piece 2 in the transfer path of a transfer section B is pressed to the plate-shaped small piece 2 by a rotary vibrating board 10, thus the other plane of the plate- shaped small piece 2 is polished. The plate-shaped small piece 2 is polished by the action of the rotary vibrating board 10 having the fine rotary vibration, thereby the water or the abrasive sprayed to the plate-shaped small piece 2 before polishing is prevented from being scattered, and no polishing stripe is generated on the plate-shaped small piece 2. |
