The present invention relates to an apparatus which maintains the flatness of a strip. The present invention includes: a pair of porous pad portions which are positioned apart from each other on both surfaces of the strip so as to inject air onto the surfaces of the strip; a chamber portion to which the pad portions are attached and fixed and which provides the pad portions with air; and a compressor which supplies high pressure air to the chamber portion with. Vibration or bending of the strip is prevented and the thickness of a plated surface by an air knife is made uniform so as to improve plating quality and competitiveness in terms of strip quality. |
