In tissue paper manufacturing and converting processes, the generation of edge trim waste and airborne dust particles is a constant challenge. These byproducts not only affect cleanliness and machine performance but also pose risks to worker safety and production efficiency.

At AirProControl, we’ve developed a comprehensive Tissue Paper and Trim Transport Ventilation System to address these challenges by integrating airflow control, waste extraction, and smart automation.

Why Trim Handling Matters

During high-speed production of tissue or hygiene paper products, continuous trimming is essential for maintaining edge quality and roll consistency. However, unmanaged trim can:

• Accumulate around equipment, creating fire hazards

• Interrupt production when manual removal is required

• Lead to excessive airborne fibers and poor air quality

An effective trim transport system ensures continuous collection and conveying of these materials without disrupting operations.

How the System Works

The system utilizes aerodynamically optimized ducting, high-efficiency fans, and filtration units to create negative pressure zones at critical trim removal points. Trim waste is pneumatically conveyed to compacting units or collection bins, while airborne dust is filtered before recirculation or exhaust.

Key Components Include:

• Suction nozzles placed at slitting or rewinding stations

• Trim chopper (optional) for long edge waste

• Dust extraction and filtration units (HEPA/ePM)

• PLC and HMI controls for real-time monitoring

Engineering Considerations

Designing an effective tissue ventilation system requires a deep understanding of airflow physics, paper properties, and plant layout. Critical engineering factors include:

• Air velocity: to capture lightweight trim without causing clogs

• System pressure drop: to ensure fan performance across duct lengths

• Noise control: using silencers and acoustic enclosures

• Fire/explosion risk: ATEX compliance for dusty environments

Applications

• Tissue converting lines (napkins, rolls, facial tissue)

• Toilet paper and kitchen towel manufacturing

• Paper edge trimming during rewinding or slitting

• Hygiene product packaging lines

Educational Takeaway

A well-designed tissue ventilation system is not just about cleanliness—it’s about continuous operation, worker safety, and energy efficiency. By understanding the airflow mechanics and matching the system to process demands, facilities can greatly reduce downtime, manual intervention, and occupational hazards.
