Generally, in order to manufacture various leather products such as handbags, bags, shoes, belts, wallets, etc., the leather fabric is cut and manufactured.

At this time, the leather fabric is subjected to a fleshing process in which the raw material is limed and the bond tissue or the fat on the back of the leather is mechanically shaved and cleaned, The thick leather is subjected to a splitting process in which the leather is divided into two layers and after a shaving process in which the thickness of the leather is adjusted, dyeing and emulsifying oil to impart softness and stiffness to the surface and polishing the surface with a sand paper to buff the surface of the leather with many defects in the silver state And finally polishing the surface of the leather to polish the surface of the leather.

In this way, the leather fabric is subjected to a buffing process in which the surface of the leather is polished with sand paper to smooth the surface of the leather.

Conventional leather fabric buffing involves winding both sides of a sand paper in the shape of a strip on the surface of a driving roller in a spiral form so as to overlap each other and bringing the driving roller into contact with the leather surface to rotate the driving roller, Method.

However, if the surface of the sand paper and the leather are brought into contact with each other, the polishing efficiency is lowered due to the frictional heat thereof. In severe cases, the frictional heat damages the surface of the roller. There is a problem in that it is necessary to carry out the re-booming operation after the cooling by air cooling by the ambient temperature.

In this way, since the cooling is performed through air cooling, productivity is deteriorated due to a cooling time delay.
