Product Description

Product Description

Bow Roll is known as Spreader Rolls, Bowed Rolls, Curve bar Expanders, Banana Rolls, Camber Rolls, and Wrinkle removing Rolls. Bow Rolls are available in rubber surface, hard chrome surface and also Teflon covering for non-sticking applications. Hard chrome surface Bowed Roller is used where speed is more than 300 meters minutes. If the speed is more, the bigger diameter is used to reduce the rpm of the roll.
Curved rubber roller has a certain arc in the longitudinal direction, it is fixed by the ball bearing and rotatable.
When the paper is rotated through the roller, it will be stretched in the longitudinal direction because of the certain curvature of the curbed rubber roller. The roller can stretch the paper to eliminate wrinkles and prevent the material in the cutting process.In other words, curved shaft fixed and the bending rubber roller would rotate well.

 

Working Principle

The difference between normal straight roller and curved roller is whether the axis has radian. In fact, we can think of a normal straight roller as a special curved roller with an axis radius of infinite days. In the process of paper production and processing, due to the shrinkage force of paper cross-section, the paper often appears wrinkles during operation. In the application of the arc roller, when the coil is close to the entrance span L of the arc roller, the edges of both sides of the paper begin to tilt towards the end of the corresponding arc roller, and then slowly stretch the paper to obtain the tension effect, so as to prevent wrinkling. When the paper contacts the surface of the curved roller, the edge of the paper will move further, so that every point of the paper is transported perpendicular to the roller surface.

Function

It is widely used for the paper, film, textiles and similar machine and equipment.
In the process of paper production and processing, due to the shrinkage force of paper cross-section, the paper often appears wrinkles during operation. And the bow roll in the paper wrinkle has superior performance.
The main function of the tension roller in the transverse direction is the anti crease function. The selection of the arc roller will determine the tightness of the paper, thus affecting the anti wrinkle effect.

characteristics

1. Bearing ring for internal structure.
2. Bearing installed in the rubber sleeve, resulting in small swing torque.
3. Smooth rubber surface without any negative impact in the material.
4. Roller face angle can be adjusted freely.

5.Better high temperature resistance, abrasion proof, anti-adhesive, and easy to clean.
6.The highest speed:2000m/min.
7.Different surface processing methods, such as Sand-blasting,Chrome plated,cover grooving.Special executions upon request.
8.Suitable machine: Cutter machine,Re-reeling machine,coating machine and paper machine.
