Coater equipment is divided into in-machine type and out-of-machine type in the process of paper machine. It is divided into single layer coating and double layer coating according to the number of coating. In-machine coating is equipped with a coater on the paper machine to make papermaking and coating continuous. Double-coated paper has better printability than single-layer coated paper, and can improve the quality of coated paper. There are mainly three types of coater used for coating operations: roll coater, air doctor coater and blade coater.Main production: kraft cardboard, white cardboard, art paper, matte paper, two-side offset paper, carbonless copy paper, thermal paper etc.

Wire section Classification:multi-layer wire section,cylinder section
Double roller section/multi-roller press,its function is to keep the original paper in a certain tension and moisture during dehydration,so that the paper is not easy to break and crack when entering the drying section.
The dryer section of paper machine is composed of DCS thermal control system(single cylinder or multi-cylinder ),GCS steam condensation system,closed air hood and heat exchange ventilation system.
