The arc roller is a roller that has a certain curvature in the longitudinal direction and is fixed and rotatable by a ball bearing. Because the curved roller has a certain curvature, when the paper/film is rotated by the guide roller, the paper/film will be elongated in the longitudinal direction to achieve the effect of stretching the web, eliminating wrinkles and preventing the web from progressing Possible interleaving during material slitting.

4.Curved roller installation

Depending on the material of the web, the wrap angle is generally between 10° and 100°, the paper is around 20°, the wet web is 30°-60°, the fiber is 25°-40°, and the plastic film is 10°-20°. In order to achieve a good flattening effect, the unwinding direction and the web travel direction must be perpendicular, the lead-out stroke is 2 to 3 times the diameter of the guide roller, and the lead-in stroke is twice the lead-out stroke. Transportation precautions: When transporting and hoisting curved rollers, it is strictly forbidden to hoist the roller surface, and the shaft ends at both ends of the arc roller must be hoisted.
