Machine Wet End TRIZ Cases

Multi-thread binding reduces machine side dimples and sheet markings while improving fiber retention and dewatering homogeneity.

Aligning warp binding yarn knuckles creates hydrating grooves without reducing warp density, maintaining rigidity while improving hydration.

Partially aromatic polyamide monofilaments reduce water absorption and shape change while improving abrasion resistance in paper machine clothing.

Dynamic oscillation adjusts fabric amplitude to prevent edge damage and web breaks from uneven wear.

Segmented self-supporting units isolate vibrations and reduce assembly time in papermaking frames.

Rotating adjusting ring with angled slots converts rotary motion into precise radial rod displacement.

A warp-weft double woven base fabric uses alternating MD and CD yarns to form a uniform structural repeat.

Wider spiral coils reduce pintle density, lowering manufacturing costs and easing stuffer insertion.

Nested intermediate pipes fastened to inner flow pipe surfaces eliminate separate fitting elements and reduce manufacturing complexity.

Plastic overmoulding joins an insert element to a carrier screen, eliminating separate laser cutting steps and register fluctuations during paper production.

Modular guide plates and turbines adapt to varying papermaking geometries, resolving the trade-off between system complexity and energy recovery performance.

Sieve pressing extracts cellulose from viscous sludge, achieving 60% yield and 95% purity.

Segmented humidifier elements control moisture distribution across a fiber web, preventing quality variability from uneven wetting.
