Circular Looms TRIZ Cases
- Volumized Carbon Fiber Tows for Uniform Composite Densification
Air-jet manipulation spreads and volumizes carbon fiber bundles to improve fiber distribution, reduce porosity, and support homogeneous densification.
- Carbon Fiber Tow Volumization for Uniform Textile Densification
Air jet volumization spreads carbon fiber tows without damaging tension, improving fiber coverage and densification uniformity.
- Variable-Diameter Circular Loom for On-Demand Woven Garments
Body-scan measurements drive a variable-diameter circular loom to weave custom garments on demand with less fabric waste and faster production.
- Circular Loom Orbit Recesses for Uniform Warp Thread Tension
Narrow orbit recesses and a movable guide device keep warp thread tension uniform at high weaving speed while reducing wear and vibration.
- 3D Woven Textile Manufacturing via Rotating Warp and Moving Weft
Rotating warp yarns and moving weft yarns creates seamless 3D textiles, eliminating fabric waste from cutting and sewing operations.
- Warp Yarn Breakage Detection Using Gravity Drop Wire
A gravity drop wire triggers a sensor upon yarn breakage, reducing downtime in dusty weaving environments.
- Non-Contact Shuttle Drive Using Magnetic Attraction and Repulsion
Alternating magnetic attraction and repulsion sections guide the shuttle without mechanical contact, eliminating warp thread damage and reducing maintenance.
- Automated Weft Bobbin Changing Mechanism for Circular Looms
An automated guide and gripper system replaces spent weft bobbins on circular loom shuttles, eliminating manual intervention and reducing idle time.
- Net Shape Preform Manufacturing Using Multi-Axial Fiber Strips
A needled preform manufacturing apparatus delivers multi-axial narrow fiber strips to build net shape preforms with controlled orientation.
- Warp Stop Motion Detector for Circular Loom
A warp-tape monitor clamps the ribbon end at rest position to secure the material.
- Circular Loom Partial Heald Ceramic Inserts
Ceramic inserts in thread eyes reduce friction between heald elements and warp threads during high-speed weaving operations.
- Circular Loom Shuttle Orientation for Centrifugal Force Reduction
Angled weft spool axis reduces shuttle mass, lowering centrifugal force and wear while increasing picks per minute.
- Circular Weaving Machine Movable Warp Bobbin Devices
Movable warp bobbin devices feed threads directly to the weaving plane, eliminating thread wear from multiple deflections.
- Circular Loom Shed Forming with Pivoting Elements
A circular loom uses pivoting elements driven by a control cam to impart alternating movements to warp thread lifting means.
- Tubular Woven Preforms for Seamless Axisymmetric Composites
Interweaving warp and weft yarns forms a seamless tubular preform, resolving the inability of contour weaving to produce complex axisymmetric shapes.
- Composite Shuttle Design for Circular Looms
Composite shuttle frames resist centrifugal deformation to enhance weaving productivity and fabric quality.
- Multi-layer circular woven fabric with decoupled warp threads
Movable warp threads enable partial multi-layered sections in circular fabrics without increasing device complexity.
- Weft Tension Control via Electromechanical Torque in Circular Loom Shuttles
A shuttle device regulates weft tension using a deflection sensor and variable electromechanical load to adjust braking torque on the ribbon spool.
- Multilayer Fabric Formation via Winding Yarn Carriers
Binder yarns stitch pre-positioned winding layers without interlacing, eliminating crimp-induced stiffness loss in composite structures.
