Paper making machines have an extra smoothing process called a calendar .Calendar consists of several rollers arranged vertically one upon the other, By running the almost dry paper web between the rollers under high pressure, the paper is compacted and smooth. The pressure applied to the web by the rollers determines the finish of the paper.
The primary purposes of the calender are can be summarized below.
Increase the quality of the final product.
Make the paper surface extra smooth and glossy
Gives it a more uniform thickness to the final product.
Calender Machine for Paper & Board Production
Our calender machine is engineered to significantly improve the surface quality, smoothness, and gloss of paper and paperboard. Widely used in printing paper, coated paper, kraft paper, packaging board, and specialty grades, the calender ensures excellent sheet finishing through precise pressure and temperature control.
Designed for high-speed, stable operation, our calenders are available in soft-nip, hard-nip, multi-nip, and online/offline configurations, providing optimal flexibility for different production requirements.
