Rubber Covered Spreader Roll High Temperature Resistance Abrasion Proof

Spreader roll basis information

The spreading effect of the spreader roll is obtained through the curved steel shaft onto which rotate some rolls mounted on ball bearings. Externally onto the rolls is fitted, as a rule, a rubber sleeve which is free to rotate . The curved spreader rolls is used for plastic films, paper, fabrics and similar products, or any time the installation of other types of roll is impossible.

Spreader roll warpping angle

The wrapping angle "W" is determined by the type of material being processed.

The following angles of wrap are recommended

Spreader roll working principle

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 spreader roll, when the coil is close to the entrance span L of the spreader roll, the edges of both sides of the paper begin to tilt towards the end of the corresponding spreader roll, and then slowly stretch the paper to obtain the tension effect, so as to prevent wrinkling. When the paper contacts the surface of the spreader roll, the edge of the paper will move further, so that every point of the paper is transported perpendicular to the roller surface.

Spreader roll with rubber surface

1. We can supply different kinds of rubber sleeves to suit customer's application environment. The face of the rubber can be processed in special way ,such as cover grooving , teflon.

2. This series of rolls is used many materials: Plastic fims, paper,foil,fabric and so on.

3. Compare to straight-line rolls, this series roll has more stable spreading effect.

Spreader roll with metal surface

1. Better high temperature resistance, abrasion proof, anti- adhesive, and easy to clean.
