This machine consists of two groups of surface sizing roller coating head, the top uses dual layer heat preservation heated air circulation hot chamber with heat pressing laminating device, it products product by cooling draw-out and coiling. The characteristic is that it can continuously carry out surface sizing and it can complement the shortcomings of single-plate sizing. It can achieve the effect, which the coating machines in current market cannot achieve, it uses reticulate patternroller to carry out sizing roller coating. The has good ventilation property, hand touch, even sizing, clear pattern and it is applicable for the surface processing of leather and textile fabric.
