Lap Forming Devices TRIZ Cases

Venturi air supply and fiber refining separate fibers before air-laying, reducing clumps while producing uniform low-basis-weight webs.

Segmented drum housing and localized seal units prevent fiber scattering while avoiding material accumulation on the transport roller.

A cross-lapper shroud belt guides the web around a deflection roller, reducing centrifugal force disturbances that degrade pile structure quality.

Perforated drums inject hot moist air into cotton batts to ensure uniform moisture distribution while preventing lint accumulation on drum surfaces.

Grooves on a non-vacuum diverting roll channel air expelled during web compression, preventing detachment at high speeds and eliminating costly suction systems.

Perforated cover strips vent trapped air from fiber webs before deflection points, preventing bubble formation and creases during high-speed processing.

Acute angle carding and plaiting machines enable defined fiber orientation on moving belt, resolving tensile force constraints in composite manufacturing.

Varying the discharge belt travel profile below the web outlet minimizes eddy formations and turbulence at fiber pile edges during high-speed laying.

A fleece laying device uses separate cover belts to guide card webs into a depositing gap while a pile conveyor belt provides stable clamping pressure.

A rotating roller table replaces suction means to eliminate fiber clumping and ensure consistent density in mineral wool production.

Adjustable air inlets and agitators eliminate screens to improve fiber distribution uniformity while maintaining high throughput.
