Due to the slaughter, a leather appearance originally was looked not uniformity, irregularity and also, Leather grain is not smooth effect of external impact(STAMP, INJURY, TICK MARK AND SO ON), The mainly object of leather process after grain coating, cover the scar to apply artificial hair cell or more deeper and bigger embo(ex: OPEL, BUFFALO, CROCDILE, SNAKE AND SO ON) to leather Our IRONING & EMBOSSINBG M/C can possible Embo & Ironing working according to the object of working and consist of Ironing M/C .   2.THROUGH FEED SAMMYING MACHING Organism like Protein, fat from raw hide, if it tan a hide at tanning process by chrome, changes to Inorganic compounds, at this point we called “wet blue condition“ WET BLUE be in a wet state, can proceed to next step after squeezed water out and made low the water percentage, This machine can squeeze the water from WET BLUE,   3.THROUGH FEED ROLLER COATING MACHING After finished dyeing process, we called “CRUST LEATHER” which is condition of drying, but the dyeing is not good for coloring on the leather also, there is a fault exposed the scar on the grain. The coating process of leather can be devided into two parts; one is auto spray process(pass the leather into the rotary spray booth) and the other is roller coating process(pass the leather after the pigment put on the rotation roller) . AUTO SPRAYING PROCESS generates the arsenic acid dust and gets worse atmosphere, not elegant the state of coating. Also, the high price of pigment and the loss of variety chemicals can give bad effect to production cost So, many tannery use the roller coating M/C nowadays.
