7 Benefits of Roll Barring Prevention

Consistency and quality control are key considerations for every industry. Roll barring presents a major obstacle to these two essential elements of your company's output, creating inconsistencies in your final product and resulting in inefficiencies that affect every level of your business from the manufacturing floor to the front office.

The benefits of eliminating roll barring from your production line are numerous. We've compiled a list of the top 7 improvements you can expect by taking advantage of PRG's "No Rolls Barred" grinding process:

1. Customer Satisfaction -- Eliminating roll barring from your production line results in a more uniform final product that your customers will appreciate.

2. Sheet and Web Strength -- Roll barring can dramatically decrease the tensile strength of your finished sheets and wet webs. By providing a truly smooth and concentric roll surface, you increase sheet and web strength for your converting group and your customers.

3. Improved Printability -- Calendar roll barring creates sheet inconsistencies that decrease the overall printability of your final product. Reducing these inconsistencies by eliminating press and calendar roll variations drastically improves the uniformity and printability of your final product.

4. Longer Roll & Bearing Life -- Use coatings on all applicable rolls. Surface coatings like Roll Armor protect the surface of your rolls from wear and extend their production life, resulting in less frequent replacement requirements.

5. Reduced Grinding Frequency -- The "chatter" that results from roll barring extends and expands even the smallest inconsistency across the surface of your rolls. That means more frequent grinding is required to keep your rolls in spec.

6. Reduced Waste -- Installing barred rolls requires considerable fine-tuning on startup and grade changes. This creates waste between grades. Eliminating roll barring from the process reduces this waste and results in a more efficient production line.

7. Easier Caliper Control -- Eliminating roll barring enhances the profile of the product during the production process. This allows for uniform printing and increases production efficiencies.
