Curved rollers play a key role in papermaking machines. They can effectively flatten wrinkles and expand the width, thereby improving paper quality and production efficiency. At the same time, curved rollers can also be used in other industries, such as plastic film processing, textile processing, non-woven fabric processing, packaging products, coating processing, etc.
Mandrel: A steel shaft with a specified curvature, which is the basic part of the curved roller.
Bearing: Installed on the mandrel to reduce friction and wear. For example, rolling bearings can be evenly distributed on the surface of the mandrel.
Roller sleeve: A rotatable curved roller surface, usually made of rubber, to better adapt to different substrates.
Adjustment component: Used to adjust the bending direction and angle of the curved roller to improve the overall adjustment accuracy.
The main function of the curved roller is to eliminate wrinkles in the web during travel and prevent possible staggering during material slitting. It uses the curved curvature on the roller surface to generate a contact area from short to long when the material passes, thereby generating a force from the middle to the edge of the material to achieve the purpose of stretching the web.
