tensionless accumulator solutions for sensitive nonwoven webs

Since the 1970s, CAMPEN Machinery A/S has supported nonwoven producers with efficient web handling systems. Our tensionless accumulator provides reliable buffering for sensitive and lightweight webs before winding. It enables low-tension web handling, minimises waste, and protects delicate nonwovens, including meltblown, wetlaid, and spunbond formats. By choosing CAMPEN, you benefit from robust, easy-to-operate solutions that help reduce web breaks, increase winding quality, and raise equipment effectiveness.

Gentle accumulation solutions for fragile nonwovens

Handling fragile webs requires stable, tension-free accumulation. The tensionless accumulator from CAMPEN uses a belt-based system that buffers your line and keeps web tension consistently low. This system is ideal for sensitive materials such as lightweight spunbond, meltblown, and wetlaid products where maintaining surface finish and structure is critical. Controlled loop formation and synchronised belts ensure gentle web management, providing even laydown to the winder without damaging the fibres.

Advantages of low-tension web accumulation

Low and even web tension helps prevent edge cracks, neck-in, and web breaks.
Decouples upstream variations from your winder’s speed profile to achieve stable operation.
Smooth winder synchronisation prevents tension spikes during starts, stops, and splicing.
Stable roll build leads to fewer winding defects and better downstream converting.
Process safety is increased with automated loop control, reducing the need for operator intervention.

Compared to roller or festoon accumulators, our belt accumulator distributes the load across a wide surface and minimises pressure points. This helps preserve delicate fibre structures and bonding. With fewer stoppages and predictable roll quality, it gives a reliable solution for the most sensitive and lightweight nonwoven materials.

Technical features driving performance and product protection

CAMPEN’s tensionless accumulator is designed to deliver productivity, quality, and reliability. Combining robust mechanics with precise motion control, the solution offers flexibility for a wide range of web types and production needs.

Driven belt sections with low wrap angles lower friction and prevent fibre pick-up or glazing.
Closed-loop tension and loop control guarantee stable web force during speed changes.
Wide belt surfaces are specifically tailored to handle sensitive and lightweight materials.
Gentle infeed and outfeed geometry prevent wrinkling and support smooth web guidance.
Easy integration with line PLCs and winder controls eliminates tension spikes at splices and roll change.
Ergonomic frame design and integrated safety features allow for quick cleaning and maintenance.

Each tensionless accumulator is configured for your production needs. Options include multiple belt widths, loop lengths, and sensor packages to match your specific materials and process speed. Additional features are available, such as contact-minimising options for meltblown lines or edge stabilisation for spunbond and wetlaid webs. This ensures reliable accumulation performance and protection for your product quality, helping prevent web breaks and defects across all lightweight nonwovens.

Custom integration and long-term technical support

Continuous production and minimal downtime are vital for nonwoven manufacturers. CAMPEN works closely with your engineers to integrate the tensionless accumulator into both new and existing lines with minimal disruption.

Comprehensive process surveys and accurate sizing ensure the right accumulation capacity for your process.
Integration with your existing drives and automation helps reduce installation time and simplify training.
Retrofit options are available to upgrade older lines and improve roll-to-roll handling efficiency.
Factory and site acceptance testing verify safety, performance, and consistent quality before handover.
Full spare parts service, remote technical support, and operator training help you maintain high performance with predictable costs.

The CAMPEN approach is always solution-focused and process-oriented. Whether you require a belt accumulator module or a complete web accumulator section with advanced synchronised winding, we deliver robust, reliable equipment. Our technical support helps maximise uptime, reduce waste, and consistently safeguard product quality for every nonwoven production run.
