- Roller Transport Control for Stable Sheet Feed Under Speed Fluctuation
Adaptive roller-speed control uses material state and position feedback to keep sheet transport stable despite motor disturbance.
- Tissue Press Felt Structure for Higher Dewatering in Long Nips
A press felt with dense MD threads and less nonwoven material improves nip dewatering, raising tissue dry content for higher-speed production.
- Seamed Forming Felt Structure for Durable Tissue Machine Operation
Optimized MD thread diameter and density strengthen the seam felt, improving dewatering and extending forming felt life in tissue machines.
- Polyurethane Shoe Press Belt for Uniform Strength and Durability
A polycarbonate-diol polyurethane layer suppresses local strength variation in shoe press belts, improving wear and fatigue durability.
- Sheet Feed Pipe Rectification for Uniform Fiber Web Formation
Trapezoidal rectifying plates in the sheet feed pipe suppress swirling airflow, improving fiber distribution and sheet quality consistency.
- Shoe Press Cover Copolymer Layer for Chemical and Crack Resistance
A thermoplastic elastomer copolymer layer with textile reinforcement improves shoe press cover chemical, abrasion, crack, and swelling resistance.
- Sheet Shaping Rollers With Idling Gear for Web Tip Thickening
An idling gear and one-way clutch fold the web tip to increase thickness, preventing heating-roller adhesion, buckling, and paper jams.
