- Drafting Roller Stepper Control for Load Torque Monitoring
Adaptive stepper current control tracks drafting load torque without encoders, improving efficiency and detecting fiber band or roller abnormalities.
- Multi-Feed Air Spinning With Split Rollers for Direct Web Blending
Separate fiber webs are drawn at independent speeds and blended by tangential air jets in one spinning chamber, cutting recalibration and extra processing.
- Spinning Draft Roller Stop Structure for Faster Roving Cutoff
An apron guide roller and segmented wedge stop structure shorten lower belt stopping time and reduce excess roving feed after breakage.
- Drafting Unit Load Carrier with Reference-Guided Roller Positioning
Reference structures and spring loading align upper rollers precisely, easing drafting unit maintenance while keeping clamping force consistent.
- Fiber Bundle Condensing Structure for Faster Suction Attraction
An angled suction-slit inlet keeps airflow fast and stable, pulling fibers onto the transport belt sooner to reduce disorder and stabilize yarn quality.
- Core Yarn Clamping Roller Groove for Full Filament Coverage
A grooved clamping roller lets the filament bypass the clamping line, enabling speed variation and full staple fiber coverage in core yarn.
