The paper calender roll (also known as fibre roll or wool roll) involves pressing layers of various types of fibre paper onto a metal mandrel under high pressure (in the longitudinal direction), followed by machining processes such as turning, turning and grinding. Paper pulp rolls achieve calendering, embossing, and densification through elastic deformation combined with frictional compression, and are used in pairs with metal hard rolls.

Paper calender rolls are widely used in finishing processes within the paper, textile, film and metal foil industries. They are primarily employed for calendering, embossing and texturing of materials such as paper, fabric and leather, and can also be used in processes such as plastic film calendering and cold-rolled steel sheet polishing. In recent years, the application of this product has gradually expanded into the calendering of new materials such as non-woven fabrics and carbon fibre fabrics.

Paper calender roll, manufactured primarily from wool paper, offer excellent performance characteristics: As the paper used for calendering roll (wool paper) possesses good elasticity and dimensional recovery under pressure, and does not deform when exposed to heat in high-temperature working environments, the use of paper pulp rolls ensures that the resulting paper, fabric or leather products have uniform thickness, minimal deformation, and excellent texture and gloss; Furthermore, as they remain stable even in high-temperature working environments, they effectively ensure the consistency of product processing quality.
Currently, the types of paper calender rolls (fibre rolls, wool rolls) that are relatively well-established in relevant fields both domestically and internationally include: wool paper rolls, cotton pulp paper rolls, cotton rolls, wood pulp paper rolls, non-woven fabric rolls and a small number of aramid paper rolls.
