What is Lathe Slitting?

Lathe Slitting—also known as log slitting—is a converting process where a master roll (log) of material is mounted onto a rotating mandrel and then cut to size using a circular blade. Instead of unrolling and rewinding like in traditional slitting methods, the blade slices through the material as the log rotates in place, similar to turning on a lathe. This approach is ideal for:

Narrow-width requirements
Soft, compressible, or layered materials
High edge quality with minimal deformation
Efficient small to medium production runs

Our Technical Capabilities

Minimum Width
From 2 mm (material-dependent)
Maximum Roll Diameter
Up to 550 mm (material-dependent)
Tolerance
As low as ±0.2 mm
Core Types
Paper (76 mm standard), plastic, or custom
Materials Handled
PSA tapes, foams, felt, films, textiles, etc.

As a 3M Select Converter and tesa Platinum Converter, we are recognized for our expertise in slitting some of the most advanced and trusted adhesive tapes on the market. Our production lines are optimized to handle even the most challenging materials from global leaders like 3M and tesa.

Lathe Slitting Process: High-Precision Roll Conversion Tailored to Your Needs

At EKO-TECH, our Lathe Slitting capabilities form the backbone of flexible roll-to-roll conversion. This method allows us to deliver precision-cut rolls in virtually any width, engineered to match your exact production needs. Whether you’re working with tapes, foams, or specialty laminates, our equipment and know-how ensure optimal performance and consistent results.

Materials We Convert Using Lathe Slitting

Technical Foams: PORON®, BISCO®, cellular rubber
Adhesive Tapes: Single- and double-sided, acrylic or rubber-based
Films: Polyester, PE, PET, PVC, PTFE, UHMW-PE
Special Laminates: Adhesive + foam, foil + fabric, and more
Hook-and-loop: Velcro-type fasteners on rolls
Paper & Felt: For gaskets, acoustic insulation, spacers

Advantages of Lathe Slitting

Extremely Clean Cut Edges
Thanks to the single-blade motion and rotary method, the cut is smooth and deformation-free—especially crucial for technical foams and multi-layered laminates.
No Material Stretching or Deformation
Ideal for pressure-sensitive materials and non-wovens that could be affected by traditional tensioned slitting.
Shorter Setup Times & Flexible Quantities
Excellent for small series production, fast prototyping, and urgent orders.
Minimal Waste Generation
Efficient layout and direct log processing reduce scrap and optimize yield.

Industry Applications

Electronics: Spacer pads, insulation layers, thermal foams
Automotive: Gaskets, acoustic components, assembly aids
White Goods & HVAC: Seals, spacers, mounting strips
Packaging: Protective foam tapes, liner slits, edge protectors
Railway & Transport: Laminated structural materials, cushioning components

From Slitting to Final Format

At EKO-TECH, Lathe Slitting is often the first step in a complex converting chain. After cutting the logs to your exact width, we can further:

Laminate with adhesives (Acrylic, Rubber, Silicone, or HAF)
Die-cut or kiss-cut into final parts
Re-roll using cross-wound spooling
Apply custom liners or split-backing

Summary

Lathe Slitting is more than a cutting process—it’s a strategic step in delivering tailored, high-quality converted materials that seamlessly integrate into your operations. With EKO-TECH’s machinery, converting expertise, and status as a certified partner of leading global brands, you get more than a roll—you get a production-ready solution.
