Description

Technical Field

[0002] A roll-to-roll coater is a device used for continuous production of coated products. It is mainly used for surface treatment of materials such as paper, plastic, metal, and textiles. A hot melt adhesive coater is a device that does not require solvents, does not contain water, and is 100% solid and fusible. It is solid at room temperature and becomes a liquid adhesive that can flow and has a certain viscosity when heated and melted to a certain degree. The hot melt adhesive is coated on the base material, which includes some films, paper and other materials.

[0003] In actual use, it is inconvenient to directly reel up the substrate after coating, the processing is discontinuous, time-consuming and labor-intensive, affecting the smoothness of the entire coating process, and not in line with the concept of energy saving and environmental protection.
