Basics on Stahl* Fold Rollers & Gripping

In the world of folding, positive, consistent grip is everything. Without it, productivity drops and waste gets expensive. Here’s a quick guide to common gripping patterns so you can match performance and wear to your work.

Common Stahl* roller patterns

Standard urethane pattern

The steel land between urethane bands is wider than each band. This was the OEM standard for many years and offers balanced grip and life for general work.

Super-grip with soft polyurethane (PU)

The steel land is narrower than the soft PU bands, so bands slightly overlap the sheet path for increased grip— great on slippery stocks. Because the compound is soft (sponge-like), improper roller settings will accelerate wear.

Super-grip with urethane

Delivers most of the super-grip advantage with improved longevity versus soft PU. It’s the best compromise of grip and durability among Stahl* casting roller patterns.

Spiral urethane pattern (Stahl* style)

Maximizes contact area between stock and roller for steady feed on challenging jobs.

Repair & recovery options

Consider recovery when:

  • The roller’s steel core shows excessive wear.
  • You can afford the machine downtime for recovery.
  • Budget favors repair over replacement.

Our typical recovery process:

  1. Inspect each roller to confirm it’s a good candidate.
  2. Strip, clean, and straighten the core.
  3. Apply new urethane to spec.
  4. Finish-grind to size and profile.
  5. Final QA inspection.

Rule of thumb: the softer the urethane, the stronger the grip—but the faster it wears. For coated stocks, super-grip patterns usually perform best.

MBO* style fold rollers

Unlike banded Stahl* rollers, MBO* rollers use a spiral pattern and can typically be reground but not recovered.
