Needling Machines TRIZ Cases
- Apparatus for compacting and/or structuring a nonwoven, and a structural shell
See how axially segmented rings enable easy handling and mounting of structural shells while ac
- Nonwoven Web Stretching After Needlepunching Shrinkage
A transverse stretching stage applies more force at web edges after needling to correct shrinkage, improve mass uniformity, and stabilize winding.
- Hydroentangling Drum Spacing With Angled Wires for Drainage
Angled wires on a perforated base drum keep spacing open for water drainage, reduce fiber jamming, and simplify hydroentangling drum manufacture.
- Cross-Direction Stretching for Needlepunched Nonwoven Uniformity
Offset ringed rollers stretch a needlepunched fiber batt more at the edges to counter shrinkage, improve density uniformity, and ease winding.
- Water Bar Suction Chamber With Air Injection for Mist Control
Air outlets near the nozzle ports keep the water jet bundled and improve suction of spray water, helping prevent droplets from marking fabrics.
- Carbon Fiber Preform Web Formation for Through-Thickness Needling
Air-laid or wet-laid carbon fiber webs with thermoplastic binder enable needle-punched preforms with higher shear strength and workable fiber volume.
- Helical Continuous Fiber Brake Rotor Preform for Uniform Carbon Matrix
Continuous helical fiber streams replace woven layers in brake rotor preforms, improving carbon matrix uniformity while cutting handling and cost.
- Robotic Needling Head Trajectories for Complex Textile Preforms
Parameterized robotic needling paths and head orientation avoid collisions while forming non-axisymmetric textile preforms.
- Felting Needle Shaft Geometry for Easier Board Insertion
A stepped shaft with a slightly smaller guide section enables easier felting needle insertion while reducing needle board wear and bending risk.
- Polymer-Sheathed Needle Arrays for Clean Z-Channel Formation
Polymer-sheathed metallic needles form z-channels in fibrous preforms while reducing metal contamination and localized deformation.
- Ceramic Needle Array for Clean Z-Channel Formation in CMC Preforms
Ceramic filament needles form z-channels in fibrous preforms without metallic particle contamination, helping preserve CMC integrity.
- Movable Fluid Jet Head for Selective 3D Fiber Bonding
A manipulator-mounted fluid jet head enables localized 2D and 3D fiber bonding, improving design flexibility and reducing material waste.
- Nonwoven Garment Arrays With Entangled Seams for Stable Insulation
Fiber entanglement forms non-linear seams that hold fill in place, cut garment process steps, and improve recyclability.
- Angled Water-Jet Transfer of Nonwoven Webs With Less Fiber Washout
Angled high-pressure water jets consolidate and lift nonwoven webs onto a suction drum, reducing fiber washout and plant length.
- Composite Nonwoven Fabric Headbox for Uniform Short-Fiber Distribution
A cross-flow headbox with turbulence generation distributes short fibers uniformly over a long-fiber layer in wet-laid production.
- Right-Angle Needle-Punching Mechanism for Angular Preforms
Paired right-angle needle plates punch both sides of angular preforms to improve density, shape regularity, and corner strength.
