The new DIENES knife holder generation “Long Life” is a groundbreaking innovation in the slitting industry, combining the latest features and technologies for the first time. “Long Life” stands for full options and, with its user-friendly design, addresses key challenges in converting processes. The DIENES knife holder PSA-DF-CSL “Long Life” exemplifies exceptional functionality and effectiveness, setting a new standard for precision and durability in slitting applications.
CSL3.0 „Long Life“ – The slitting system for maximum efficiency in nonwoven production.
More running time. More quality. Less downtime. Leading nonwovens manufacturer breaks knife life-time record in first attempt,
1. Challenges in the nonwoven industry
Our latest generation of knife holders has already gained the trust of our first customers. Many slitting systems, equipped with multiple knife holders, have been successfully upgraded to the latest DIENES technology. But despite the highly automated lines, many slitting systems still use the conventional knife holders that
- Apply uniform pressure across knife groups
- Wear out prematurely
- Cause waste and dust formation
- Require frequent knife changes and downtime
- Cannot react to material fluctuations

This model, the PSA-DF-CSL “Long Life” knife holder incorporates all the DIENES features that make the knife holder particularly effective and user-friendly.
On the one hand, it includes the latest DIENES technology with the brand new, patented CSL3 (Constant Side Load), and on the other hand it is user-friendly thanks to the tool-free knife changing „Easy Change“ and the simple depth adjustment via Depth Control.
In case collisions of top knives and bottom knives, or instable slitting forces are a common problem, by using the “Long Life” knife holders, the offset between top and bottom knives can be increased in the HMI (Human Machine Interface) of the slitter. As a result, collisions are avoided and the knife holder applies a controllable force for all cuts with a distance between 0.5 and 3 mm.
Requirements in the nonwoven industry
- Cutting quality: Frays, tears, or fused edges lead to functional problems or complaints.
- Process consistency: Even minimal deviations affect packaging, sealing, or skin compatibility.
- Availability: Every minute of downtime reduces output.
- Cost-efficiency: Wear parts, waste, and rework drive up costs.
The solution
Our solutions are designed to help you tackle the challenges of slitting nonwovens and paper while enhancing the quality and efficiency of your production. We aready know the challenges and the requirement, but what are the solutions that DIENES has to offer?
What is CSL3 (Constant Side Load)?
Unlike conventional systems with central or general pressure application, CSL 3.0 offers:
- Ideal force-stroke characteristic for the horizontal contact pressure of the dished knife
- Extra large working window (0.5 – 3 mm)
- Process-safe mapping of cutting forces 28 – 80 N (to avoid inferior cutting edges, knife breakages and „plastic rings”, among other things
In case collisions of top knives and bottom knives, or instable slitting forces are a common problem, by using the “Long Life” knife holders, the offset between top and bottom knives can be increased in the HMI of the slitter. As a result, collisions are avoided and the knife holder applies a controllable force for all cuts with a distance between 0.5 and 3 mm.
PSA-SD-CSL „Long Life“ Knife holder
- CSL3-based (Constant Side Load) knife head with extra large working window 0.5 – 3 mm
- Dished knife (150 x 80 x 2 mm) double bevel
- Precise adjustment of the slitting force due to compressed air supply
- Depth adjustment via Depth Control – sensor based LED indications for overlap adjustment of top and bottom knives
- Super-rigid design based on double axis guidance
- DIENES angle plate
- Two compressed air connections (one for knife holder stroke vertical & horizontal, one for connecting pin)
- Can be exchanged with a lot of PSA-DF models in the field (subject to be checked on an individual case)
The PSA-DF-CSL “Long Life” knife holder is compatible with many existing PSA-DF models, making it a cost-effective upgrade for current slitting systems. Its super-rigid design and double-axis guidance ensure stability and accuracy, even for high-speed operations.
