Prevent Excessive Belt Wear on Your Folder Gluer

How to Prevent Folder Gluer Belt Wear on Your Signature Folder Gluer

Proper folder gluer maintenance is essential to keeping your machine running at peak performance and minimizing downtime. One of the most commonly overlooked causes of costly repairs is excessive belt wear, often due to incorrect upper carrier tension.

Optimize Carrier Settings to Extend Belt Life

When installing new folder gluer belts, it’s critical to reset the upper carriers to the OEM-recommended range. Many operators believe that tighter carriers will improve performance, but this is a costly misconception. Over-tightening increases pressure and accelerates folder gluer belt wear, resulting in more frequent replacements and reduced machine efficiency.

Why Proper Carrier Adjustment Matters
  1. Extends Belt Life – Prevents premature belt stretching, cracking, and failure.
  2. Improves Machine Performance – Ensures smooth carton transport and precise folding.
  3. Reduces Downtime – Minimizes unexpected stoppages due to belt damage.
  4. Lowers Maintenance Costs – Fewer replacements and less service time saves money.
Best Practices for Folder Gluer Maintenance

To protect your belts and bottom line, keep these tips in mind:

  • Reset the upper carrier tension to OEM specs when installing new belts.
  • Inspect belts regularly for cracks, fraying, or uneven wear.
  • Avoid over-tightening upper carriers. Excessive pressure shortens belt lifespan.
  • Stick to a routine folder gluer maintenance schedule to catch issues early. 
  • Have an extra set of belts on hand for unexpected wear. This will minimize production delays while waiting for a new order.
