Production processes with rolled materials, especially film, paper or textiles, often encounter problems such as wrinkles, creases or uneven tension. The optimal solution is to install banana rolls (also known as stretch rolls). At Dessa-NV LLC, we not only manufacture and repair such shafts, but also adapt them to the specifics of your equipment.
🍌 What is a banana shaft?
This is a special roll with a curved geometry that ensures even stretching of the material during rewinding, printing, laminating or drying. Its shape resembles a curved arc (hence the name), and the design allows you to adjust the tension angle.
🔧 Design and types of banana shafts
We manufacture and service:
- Passive banana shafts are rubber-coated on a rigid curved rod.
- Active banana shafts are based on a resilient core or a rotating segmental mechanism.
- Shafts with polyurethane, EPDM, silicone or NBR coatings.
Depending on the conditions of use and temperature conditions, we select coatings with the appropriate characteristics: hardness, chemical resistance, and elasticity.
🎯 Where banana rolls are used
- Printing - for stretching rolls before printing
- Lamination and coating - for levelling the film
- Packaging - stabilising tension during rewinding
- Film and textile production - wrinkle removal
- Paper production - before cutting or gluing
🧰 Maintenance and repair of banana shafts
Banana shafts wear out in the same way as conventional shafts. Dessa-NV offers:
- Diagnostics of geometry and bearing assemblies
- Regeneration of the shaft coating (EPDM, NBR, PU)
- Balancing after repair
- Replace axle or bushings as required
💡 Why order a banana roll from Dessa-NV LLC
- Customised solutions - for a specific machine or process
- Optimal selection of coating hardness and bending angle
- Professional profile or saddle bombing grinding
- Selection of bearing group and mounting
- Warranty for all work and materials performed
📩 Does your roll material have wrinkles or "go sideways"? We will select the right banana roll or repair your existing one.
