　　造紙機機(ji)(ji)(ji)械壓(ya)(ya)(ya)(ya)光機(ji)(ji)(ji)，用多(duo)工序處理以取得良好的表(biao)面(mian)(mian)質(zhi)(zhi)量。大(da)多(duo)數紙(zhi)(zhi)(zhi)在(zai)紙(zhi)(zhi)(zhi)機(ji)(ji)(ji)后都經過(guo)(guo)(guo)機(ji)(ji)(ji)械壓(ya)(ya)(ya)(ya)光機(ji)(ji)(ji)壓(ya)(ya)(ya)(ya)光，使紙(zhi)(zhi)(zhi)面(mian)(mian)平整(zheng)一致。機(ji)(ji)(ji)械壓(ya)(ya)(ya)(ya)光機(ji)(ji)(ji)由(you)若干個冷鑄鐵輥(gun)制成，以各輥(gun)子(zi)的自重(zhong)或另加壓(ya)(ya)(ya)(ya)將紙(zhi)(zhi)(zhi)面(mian)(mian)壓(ya)(ya)(ya)(ya)平。若需要更高表(biao)面(mian)(mian)平滑度則要用超(chao)級壓(ya)(ya)(ya)(ya)光機(ji)(ji)(ji)壓(ya)(ya)(ya)(ya)光。它一般由(you)紙(zhi)(zhi)(zhi)粕輥(gun)和冷鑄鐵輥(gun)相間排列組成。根據使用要求(qiu)不同，一些品(pin)種要經表(biao)面(mian)(mian)施(shi)(shi)膠來改進表(biao)面(mian)(mian)質(zhi)(zhi)量;有的要經過(guo)(guo)(guo)表(biao)面(mian)(mian)涂(tu)(tu)布，以改進外觀(guan)質(zhi)(zhi)量或印刷質(zhi)(zhi)量。表(biao)面(mian)(mian)施(shi)(shi)膠、涂(tu)(tu)布可(ke)(ke)以用成紙(zhi)(zhi)(zhi)在(zai)紙(zhi)(zhi)(zhi)機(ji)(ji)(ji)外通過(guo)(guo)(guo)施(shi)(shi)膠機(ji)(ji)(ji)及涂(tu)(tu)布機(ji)(ji)(ji)進行(xing)(xing)加工，也可(ke)(ke)以將施(shi)(shi)膠機(ji)(ji)(ji)及涂(tu)(tu)布設備組合在(zai)紙(zhi)(zhi)(zhi)機(ji)(ji)(ji)內進行(xing)(xing)機(ji)(ji)(ji)內加工。
