Web material accumulators for sensitive nonwoven webs

“`html

Since the 1970s, CAMPEN Machinery A/S has supplied reliable web material accumulators to nonwoven producers globally. We design robust systems that protect sensitive and lightweight nonwoven webs with stable, low-tension handling before winding. Our technology minimises scrap, reduces downtime and maintains high product quality during roll-to-roll handling. We collaborate with your team to solve web handling challenges and support consistent, trouble-free production.

Low-tension accumulation solutions for sensitive webs

Our web material accumulator and belt accumulator solutions are purpose-built for sensitive nonwoven processes. Applications include meltblown, wetlaid, and lightweight spunbond webs. The system’s wide belt contact offers controlled, stable traction, helping you manage low web tension from formation to winding. Consistent tension control helps prevent web breaks, tension spikes and fibre deformation during splicing and roll exchanges. This protects web integrity and supports smooth winder synchronisation, ultimately improving overall line efficiency.

Engineered for your exact requirements, each web material accumulator is configurable for accumulation capacity, web path length and automation level. Closed-loop feedback keeps web speed and loop length precise, even during rapid changes. The accumulator buffers upstream variations, allowing safe roll changes without affecting downstream stability. We select rollers, belts and surfaces that protect delicate fibres and avoid marking, contamination or unwanted static build-up.

• Low-tension web handling reduces risk of tearing and deformation in thin or breathable nonwovens.
• Tension-free accumulation helps lower material waste from web breaks.
• Accurate loop control ensures smooth splicing and doffing operations.
• Gentle product handling protects sensitive web structures, especially in lightweight nonwovens.
• Consistent buffering supports increased equipment effectiveness and higher throughput.

Technical expertise and consistent performance

With decades of experience, our engineers dimension frames, drives and belts for wide webs and high speed applications, guaranteeing robust and reliable operation. Mechanical designs are straightforward for easy maintenance and cleaning. Electrical integration is developed in-house, aligning control parameters precisely with upstream forming and downstream winding equipment. Clear recipe management and reliable safety interlocks support smooth, repeatable production and reduce unexpected stops for your operators.

• Robust design helps cut unplanned downtime and reduces maintenance work.
• Carefully selected belts and anti-marking rollers help prevent surface defects and fibre pick-up.
• Efficient drives and optimised idle cycles help cut energy usage per tonne produced.
• CE-marked safety guards maintain operator safety for all planned interventions.
• Thorough factory testing ensures faster, trouble-free installation and startup.

We work closely with your engineering and quality teams from initial layout to commissioning. Agreed performance criteria are validated in trials. Our service team provides operator training, spare parts and upgrades for the full lifecycle of your web material accumulator.

User-friendly controls and seamless process integration

Our web material accumulators are designed for easy operation and straightforward integration with your line controls. Automatic synchronisation of web speed and loop length with the winder prevents tension spikes, ensuring safe, reliable roll-to-roll handling. Intelligent logic manages all ramps and transitions, reducing stress on sensitive webs and supporting smooth running, even with varying production speeds.

The HMI interface presents recipes and real-time production trends. Guided procedures make it easy for operators to prepare for splicing, change belts and recover after planned stops. Alarms and system messages are clear, helping your staff act quickly and safely.

• Winder synchronisation gives you even tension, better splice windows and uniform roll build-up.
• Predictive loop control stabilises the material flow from upstream equipment.
• Data logging supports process analysis and defect tracing in quality assurance work.
• Accessible parts and easy belt changes reduce planned maintenance times.
• Remote support services help resolve issues quickly and efficiently.

Suitable for processes involving meltblown filtration media, wetlaid wipes or lightweight spunbond webs, our accumulators help you achieve consistent, low-tension handling and high web quality. This results in more reliable production, fewer tears and cleaner, straighter roll formation.

Reliable partners for nonwoven production

We support nonwoven producers, converters and technical teams looking for stable accumulation of sensitive or lightweight webs before winding. Our accumulators help avoid web breaks, maintain stable tension and deliver even performance over wide widths and varying line speeds.
