Reliable web accumulators for sensitive nonwovens

Since the 1970s, CAMPEN Machinery A/S has delivered reliable web accumulators to the nonwovens industry. Our solutions focus on sensitive nonwoven webs and help you maintain process stability while protecting delicate materials. We understand your technical requirements and design robust equipment that is easy to operate and delivers consistent results. By analysing your production line and needs, we supply web accumulators that fit your process—whether you produce meltblown, wetlaid, or spunbond nonwovens. This enables low-tension web handling, stable buffering, and trouble-free roll changes, resulting in fewer production stops, improved safety, and higher product quality.

Ensuring process stability for delicate nonwoven webs

Our belt-based web accumulator systems are engineered to manage delicate, lightweight nonwovens just before winding. They create an essential buffer zone that lets you perform splices, core changes, or short maintenance stops without risking material stress or web breaks. By delivering low-tension accumulation and gentle transport, our accumulators help prevent fibre displacement and tears, particularly in sensitive nonwoven products.

We tailor each web accumulator for your specific process, integrating mechanical, electrical, and software elements for seamless operation with your upstream and downstream equipment. This leads to reliable web control, predictable uptime, and secure production operations.

• Low-tension web conveyance reduces tension spikes and minimises material waste.
• Tension-free accumulation keeps web breaks and scrap low, especially during roll changes.
• Precise loop control holds web width and tension steady across the line.
• Synchronisation with winders supports smooth speed changes and reduces the risk of errors.
• Stable buffering raises OEE and limits unexpected downtime.
• Open, accessible design supports easy operation and fast cleaning.
• Robust construction and quality components help reduce maintenance costs and extend service life.

Our long experience in meltblown, wetlaid, and spunbond web handling informs every detail: gentle web guidance, reliable nipping, simple web threading, and an intuitive HMI. This ensures consistent handling for multiple product grades and basis weights, supporting your process quality targets.

How accumulator systems improve nonwoven production

A CAMPEN web accumulator stores the web between two coordinated belt sections. The web travels across broad, driven belts that provide uniform support and reduce point loading—helping to safeguard fragile or lightweight fibres. Sensors and drives work together to measure the loop’s position and control tension, maintaining steady web flow during splicing, threading, or winder stoppages.

Advanced drive systems, load cells, and real-time control help the web accumulator dispense or receive material smoothly, following line speed fluctuations. This enables consistent web handling and reduces the risk of defects. Whether you need to buffer the web for roll changes or balance process speeds between machines, our system helps prevent web loss and supports reliable production.

• Closed-loop tension control keeps web handling steady and protects sensitive materials.
• Belt guidance is developed specifically to handle lightweight and challenging webs.
• Variable buffer capacity aligns with your process speeds and roll change requirements.
• Integrated threading modes and safety interlocks protect operators and the web during all operations.

Additional integrations and custom options

• Web widths from pilot scale to wide-format production—customised to your requirements.
• Edge guiding and web alignment deliver top-quality rolls and fewer material defects.
• Ionisation and effective dust removal help maintain a clean web and product quality.
• Data logging and remote diagnostics support efficient troubleshooting and process optimisation.

With these features, you achieve stable, low-tension web handling, accurate roll-to-roll transitions, and dependable winding operations. The end result is fewer web breaks and well-controlled processes—even under demanding conditions.

Engineering support, integration and ongoing service

Every CAMPEN web accumulator is delivered as a complete, line-ready solution. We coordinate integration with your forming, drying, coating, and winding equipment—ensuring smooth interfaces and reliable communication signals from the initial start-up.

We prioritise quality and safety by using reliable components, CE-certified safety systems, and clear, operator-friendly controls. Comprehensive training and documentation are standard, making it straightforward for your team to operate and maintain the accumulator with confidence.

• Process-oriented design can lower commissioning times and reduce project risks.
• Retrofit solutions help modernise existing lines, supporting ongoing efficiency improvements.
• Spare parts supply and preventive maintenance plans help avoid unplanned stops and ensure consistent output.
• We offer on-site commissioning and 24/7 remote support to minimise downtime and accelerate troubleshooting.

Our commitment to the nonwovens sector extends beyond machinery delivery. We provide technical advice, practical solutions, and reliable service to help you meet your productivity and quality goals—both now and in the future.
