The relationship between Composite Machine and paper machine can be divided into inner type and outer type. It can be divided into single-layer composite and double-layer composite. The paper machine is equipped with a laminating machine on the paper machine to make the paper and composite materials continuous. The printability of double-layer composite paper is better than that of single-layer composite paper, which can improve the quality of composite paper.

　　There are two compounding methods. One is to compound the emulsion on the screen through multiple wet pressing operations, or add drying process after each compounding. A mechanical method of quantitatively compounding a liquid (or molten) polymer material (such as an adhesive or coating) on the surface of a material. Both ends of the combined mechanism are installed on the vertical arm of the Composite Machine. The compound mechanism moves up and down through the transmission of belt, chain or cable to compound along the screen surface.

　　Composite Machine is mainly used for film and paper surface lamination processing. This machine is to coat the rolled substrate with a layer of adhesive, coating or ink with specific functions, and then wind up after drying. The composite mechanism is composed of compound groove, mechanical parts or pneumatic parts which control the angle and pressure of compound groove. The transmission mechanism is connected with the servo or frequency conversion motor to make it control the position of the combined mechanism smoothly and accurately.
