Webs Handling TRIZ Cases
- Coiler Mandrel Stiffness for High-Strength Steel
A coiler mandrel uses pivotably mounted lugs to join segments and an expansion bar within a closed body structure.
- Rotating Arm Assembly for Web Material Roll Closing
Angular displacement of multiple arms enables simultaneous roll ejection and feeding, resolving sequential handling bottlenecks.
- Traction Control for Die-Cut Paper Expansion
Die-cut slits enable three-dimensional expansion while a spongy device and adjustable cylinder prevent roll misalignment during deployment.
- Light Curtain Object Detection for Reel Changer Safety
A light curtain detects reel entry sequences to permit access while maintaining perimeter protection.
- Automatic Core Charging and Bobbin Discharging in Plastic Film Winding
A linear actuator with a rotating supporting plate aligns cores on the winding spindle while a conveyor belt discharges wound bobbins.
- Web Winding Apparatus Air Ejection Core Attachment
Crossbar nozzles eject compressed air to guide the web end onto the rotating core, eliminating adhesive waste and equipment jamming during continuous operation.
- Reel Holder Brake Module for Food Wrapping Tension Control
A reel holder brake module applies controlled force to the shaft of a wrapping material reel.
- Roll Changer Cascade Control with Adaptive Current Pre-Compensation
A roll changer cascade control loop uses an adaptive current pre-control value to determine motor input variables for precise peripheral speed regulation.
- Tail Sealing Using Nonadhesive Phase-Change Material
Applicators deposit nonadhesive phase-change material to form mechanical bonds, resolving bond strength versus separation trade-offs.
- Dual Belt Feeder Winding Machine for Thin Foil Tension Control
A winding machine with dual belt feeders wraps material webs in opposite directions to maintain flexible tension across varying foil diameters.
- Hot Melt Winding Apparatus Eliminates Adhesive Tape Waste
A winding apparatus applies hot melt adhesive to web tubular film for direct core bonding.
- Swivel Mechanism for Rapid Roll Exchange in Wind Blade Production
A swivel mechanism grips roll shaft ends and rotates fibre sheets to enable rapid exchange cycles.
- Paper Log Rewinder Optical Position Control
Optical sensors detect actual log position deviations and trigger motor adjustments to correct winding errors caused by roller wear.
- Automatic Filter Bag Machine Reel Change System
A robotic arm automates reel replacement on automatic filter bag machines, resolving manual intervention bottlenecks and space constraints.
- Carrier-Free Adhesive Strand for Fibrous Web Connection
A carrier-free adhesive strand connects fibrous webs directly, eliminating tape thickness and maintenance costs.
- Web-travel alignment using printed features
Detect printed web features to align webs with irregular edges, resolving the trade-off between adaptability and measurement precision.
- Reel With Primary And Secondary Forks For Stable Nip Load
Primary and secondary forks maintain stable nip load on a moving machine roll, minimizing transfer defects.
- Web Transfer Suction Device for Secure Roll Feeding
A suction device captures the material web start and moves it away from the winding roll to enable automated transfer.
- Brake Mechanism for Packing Material Roll Dispensing
A dynamic brake mechanism governs roll speed to prevent tearing caused by uneven cores.
