Un-winder→ First impregnating station→ Frist Dryer Secondary→ coating machine→ Second Dryer→ Paper cutting and Stacking system.
Un-winder
Unwinder with air-swelling shafts(or non-shaft) to continuously unwind and produce, and keep the correct paper tension constant through the automatic regulating mechanism.
Two working positions with no-stop roll changing, automatic tension control (with an accuracy of ±0.5N), ensuring smooth operation of the paper sheet.
Automatic splicer（option）
Automatically paper splicing from the top. Stick the new paper web to the old paper if the roll is changed and cut off the old paper. Two edge cutting devices for the edge trimming, can save resin.
First impregnating station
It consists of a frame, S-roller, backing rollers, metering rollers, glue basin, etc. In this station paper is pre-impregnated and the glue pick-up is controlled by adjusting the gap between the metering rollers.
Secondary coating machine
Newly designed frame for more stable operation. The smoothing roller frame can be raised in its entirety to facilitate the cleaning of the anilox rollers. Two times resin covering onto both sides of the paper according to process requirements.
Dryer
Air flotation type dryer, drying the paper after first impregnator and secondary coator. The heating medium can choose to use thermal oil or natural gas. Special frame construction and insulation for energy savings.
Cooler
Attached to the back of the dryer to cool the paper. Lengths can be customized on request and equipped with a cooling device.
Web aligner
Enable accurate and reliable web tension control and aligning of the web come from dryers.
Tractor
The traction machine is the driving unit that provides traction for the entire production line. Circulating cooling water is continuously introduced into the rollers to cool the paper.
Paper cutter
Precise sheet cutting by means of START-STOP function and spin-type knife design to ensure optimized wear combined with excellent cutting quality.
Stacking system
Consists of a belt and lifting table for the stacking of finished paper. A double-layer automatic stacking system can be used as an option depending on the requirements of the production process.
As the first manufacturer in China to use natural gas as a heating medium, the RG series paper impregnating and coating line has a wealth of experience in this area and, together with excellent insulation technology, is able to achieve energy savings of 10-15% compared to other manufacturers. The fine workmanship ensures high stability during the operation and the precision of the resin pick-up.Production line made modular for easy installation by the customer.
Characteristics of Decorative Paper Impregnation Line
(1) Fully automatic: Controlled by PLC + HMI, parameters can be set easily, ensuring stable production.
(2) High precision: The amount of glue applied, moisture content, and flatness error are extremely small.
(3) High efficiency: Continuous production, with a single production line capable of achieving annual output of millions of square meters.
(4) Energy conservation and environmental protection: Waste gas is collected and treated centrally , and thermal energy is recycled and utilized.

1.What is a melamine paper impregnation line?
A melamine paper impregnation line is a production line used to impregnate decorative paper with melamine resin, which enhances its durability and aesthetic appeal. This treated paper is commonly used in the manufacture of laminate flooring, furniture, and other decorative surfaces.
2.How does a melamine paper impregnation line work?
The process involves feeding decorative paper through a series of rollers where it is saturated with melamine resin. The impregnated paper then passes through a drying oven to cure the resin, resulting in a tough and durable decorative layer.
3.What are the advantages of using melamine impregnated paper?
Melamine impregnated paper offers several benefits, including enhanced scratch and abrasion resistance, resistance to moisture and chemicals, UV stability, and a wide range of decorative options.
4.What types of decorative papers can be used in this process?
Various types of decorative papers, including solid colors, wood grains, stone patterns, and custom designs, can be used in a melamine paper impregnation line, offering versatility in the final product.
5.What are the key components of a melamine paper impregnation line?
Key components typically include unwinding stations for paper rolls, resin application systems, drying ovens, cooling zones, tension control mechanisms, and winding stations for finished rolls.
6.What are the quality control measures in place during production?
Quality control measures may include monitoring resin consistency, temperature control in the impregnation and curing processes, inspection of finished product for defects, and adherence to specified thickness and gloss levels.
