Most downfold flexo folder-gluers come stock with a series of spring-loaded hold down rollers to help control sheets being carried through folding section by transfer belts.
Conventional Folding Sections with Hold-down Rollers
Over time, the rollers are prone to wear and tear due to seized up bearings, worn out springs, and other issues that require replacement. In the interim, seized up rollers lead to uneven sheet transfer when the rollers do not properly contact the belt and maintain a hold on the sheets.

Sauer System’s Folding Section Sheet Control Upgrade eliminates the hold-down rollers in the folding section, replacing them with heavy‐duty, ultradurable, spring‐loaded sections that form a uniform and smooth surface for the belts to ride on. There is NO maintenance required to maintain the integrity of the system, no adjustments required, and greatly reduced possibility of uneven belt transfer.
System Benefits
- No routine maintenance required.
- Never replace a roller again.
- No spare parts required.
- Smoother transition of boxes / eliminates potential twisting.
- Longer transfer belt life.
- Quick installation.
