A calender is a device used to increase the glossiness of paper by applying pressure to the paper and changing the heat to improve the cleanliness and performance of the paper.

The working method of the calender is usually continuous rolling. The paper is conveyed from the paper feeding table to under the calender belt between the heat-pressing rollers. When the blade knife is in thermal chemical coating, the function of the calender is to flatten the thermal chemicals to the paper. The calender exerts pressure on the paper and changes the heat, so that the heat-sensitive coating is flat and smooth, and the calendered coating layer gradually cools to form a bright surface layer, which can better carry out the heat-sensitive paper coating step.

Moreover, the calender can also control the thickness of the chemical coating, which determines the final product quality. By using a calender, workers can ensure that the heat-sensitive coating is applied evenly and at a consistent thickness, improving paper durability while helping to reduce variability in the final product.

All in all, the calender is a key component of the thermal paper coating machine, which helps to create high-quality thermal paper.Normal, we recommend customer choose the Double-rollers calender using in the paper ciating machine line.
