Dobbies TRIZ Cases
- Embossed Industrial Fabric to Prevent Web Roll-Back and Wrinkles
See how embossed knuckle patterns on plastic monofilament fabric prevent nonwoven web floating
- Weaving Drive Mechanism Configuration via Three-Target Sensing
Three targets on the moving element let a stationary sensor determine weaving drive configuration accurately without prior movement profiles.
- Rotary Dobby Coupling for Stable Heddle Frame Motion
A dual-blade coupling locks and releases the eccentric to distribute heddle-frame forces and prevent shifting under high warp tension.
- Shedding Machine Eccentric Adjustment for Loom Heddle Frames
An eccentric adjustment system lets loom heddle frames change stroke and height precisely, while locking mechanisms fix selected positions.
- Loom Shedding Machine With Locking Eccentric Stroke Adjustment
Manual heald-frame adjustments can be tedious and inaccurate; a rotary actuator and locking system set eccentric distances precisely.
- Loom Shedding Assembly Automated Adjustment Mechanism
Automated shedding assembly replaces manual adjustments with a flap and follower member to precisely control heald frame stroke amplitude and height.
- Rotary Dobby Latch Control for High Speed Operation
Segmented latch control reduces inertia and increases operating speed while maintaining reliable force transmission.
- Rotary Dobby Notch Geometry for Wear Reduction
Local quality differentiation increases braking interface height to distribute contact pressure, reducing component wear during high-speed deceleration.
- Screw Assembly Device With Axial Locking Lugs
An axial lug arrangement prevents bending stress and loosening under vibration without increasing radial size or requiring threadlockers.
- Shed Forming Machine Dual Sealing Barriers Lint Oil Separation
A shed forming machine uses two spaced sealing barriers to create an intermediate chamber between the hood and frame.
- Loom Shedding Control via Crank Mechanism and Motor Reversal
A loom shedding method uses crank mechanisms to drive heddle frames independently while reversing motor rotation to restart motion.
- Loom Connecting Rod Length Adjustment via Wedge Mechanism
Adjustable loom connecting rod uses an inclined wedge surface to translate lateral motion into precise longitudinal length changes.
- Composite Connecting Rod for Looms with Segmented Inertia Design
Segmented composite connecting rods increase transverse moment of inertia to eliminate stabilizer devices and reduce linear mass in high-speed weaving looms.
- Shedding Machine Sealing Device Segmentation
Segmented spacers define seal channels to prevent oil splashes while lowering manufacturing costs for loom outlets.
- Coaxial Drive Unit with Electromagnetic Coupling for Loom Safety
An electromagnetic coupling links coaxial motors in a weaving loom drive unit, preventing phase displacement collisions during power failures.
- Weaving Machine Drive Shaft Torque Smoothing
Permanent magnet arrangements provide assisting torque to smooth angular speed variations and reduce energy consumption in weaving machines.
- Loom Operating Device Blank Beating Control
A loom operating device adjusts blank beating duration to prevent weft bars.
