Dryer Section TRIZ Cases
- Heat Conductive Belt for Paper Web Transfer and Drying
A heat conductive belt transfers paper webs between press and dryer sections.
- TAD Fabric Pocket Segmentation for Pinhole Prevention
Segmented pockets reduce manufacturing stresses that cause pinholes while maintaining tensile strength.
- Steel Yankee Cylinder Welding for Roundness Control
Sequential circumferential welding minimizes thermal deformation to maintain roundness in steel Yankee cylinders during high-speed rotation.
- TAD Paper Dust Control via Zoned Vacuum Hoods
Zoned vacuum hoods capture airborne dust in through-air drying papermaking systems, preventing fire hazards and maintaining operational efficiency.
- Steam Collector Tank Pressure Control for Yankee Dryer
A steam collector tank buffers recirculated steam to stabilize pressure fluctuations and prevent overheating in the Yankee drying cylinder.
- Pulp Dryer Edge Zone Cover Elements
Cover elements block air removal gaps at lateral edges to create an enhanced air pressure cushion that prevents sagging and dust formation.
- Thermally Conductive Belt for Paper Web Drying
Heating the paper web on a conductive belt before the drying section increases dry content, preventing shrinkage and web breaks at higher velocities.
