Stacked belt accumulator solutions for reliable nonwoven production

“`html

Since the 1970s, CAMPEN Machinery A/S has helped producers in the nonwoven industry to achieve stable, high-quality outcomes using advanced stacked belt accumulator systems. Our engineered solutions are tailored for low-tension web handling, supporting sensitive and lightweight nonwoven materials. This approach delivers reliable production with reduced waste and consistent process control. The stacked belt accumulator is positioned before the winder, gently buffering meltblown, wetlaid, and spunbond webs. With a customer-focused approach, we ensure your production line performs reliably from the first day, maintaining product quality and protecting uptime.

Engineered for precise web buffering and product protection

The stacked belt accumulator is an essential part of modern nonwoven lines. It provides low-tension accumulation to minimise web breaks and fibre damage during roll changes or process interruptions. The design uses multiple soft belts arranged one above another, supporting the web over a wide surface and reducing the risk of marking or stretching. This is especially important for delicate nonwovens such as meltblown, wetlaid, and ultralight spunbond grades, where even small variations can impact final product quality.

Operating principle and integration

During normal operation, the stacked belt accumulator forms controlled loops of the nonwoven web between each belt. Feedback systems, such as load cells or dancer arms, monitor and regulate web tension. This active control allows the accumulator to synchronise precisely with the winder, preventing tension spikes as rolls index, change diameter, or during splicing. Roll-to-roll handling becomes safer and web break prevention is improved throughout the production process.

Soft, wide belts maintain low web tension and prevent edge curl.
Minimises distortion of fine fibres for improved roll quality.
Reduces waste by preventing unplanned stops and web breaks.
Accurate feedback maintains uniform basis weight and cross-direction profile.
Compact vertical layout conserves floor space and optimises plant routing.
Integrates with web guiding and spreaders to ensure smooth winding.

This approach is suitable for webs below 10 g/m² as well as multi-layer laminates. Controls link with your main PLC, giving operators transparent diagnostics and quick access to settings for web and belt accumulator adjustments.

Focus on reliability and user-friendly operation

CAMPEN stacked belt accumulators are built for long-term, trouble-free service. We use robust steel frames to ensure precise alignment, even at high speeds and with heavy-duty use. Selectable high-efficiency drives maintain stable tension and reduce energy costs. Our easy-to-operate design includes clear access points, cleanable surfaces, and secure guarding for fast maintenance and improved operator safety.

Main features and production benefits

Strong machine frames resist wear and keep belts aligned over years of use.
Durable belts and idlers support trouble-free operation and long service intervals.
Tool-free belt tension adjustments reduce downtime during servicing.
CE-marked safety features support safe threading and routine cleaning.
Drives and PLC-based control allow transparent recipe changes and remote troubleshooting.
Option for antimicrobial belt surfaces increases hygiene in sensitive processes.

Widths up to 5.0 m and line speeds over 300 m/min are supported. Each web accumulator is tested before delivery, and we offer start-up assistance and operator training to secure rapid commissioning and reliable day-to-day running.

Configured for your process, team, and production targets

CAMPEN designs every stacked belt accumulator and web handling system around your specific requirements. We assess your line layout, web properties, and safety needs before defining the right solution. This customer-driven process ensures a perfect fit for your plant and material grade—whether sensitive, lightweight, tacky, or composite webs.

Adaptable options and smart integrations

Customisable loop capacity for long-duration winder stops or slowdowns.
Anti-static options and ESD controls for ultrafine or dust-prone webs.
Edge guiding and trim handling to maintain web position and reduce wrinkling.
Integration with leading PLC and drive systems for simple operation and support.
Remote monitoring for quick diagnostics and uptime protection.
Clear instructions and acceptance tests for secure operator performance.

Our engineering team helps you adapt as production needs change. Adjustments to control functions or hardware upgrades are managed for continued reliability. We support your operators and technical staff at every step—from commissioning through production and process changes.
