This stage builds the absorbent core foundation. It covers tissue feeding, pulp fiber preparation, forming, SAP dosing, ADL addition and inner cutting so the core reaches the required shape and handling condition for downstream lamination.
Unwinds the tissue jumbo roll, applies adhesive and feeds the bottom support layer into the core-forming area.
The tissue web is unwound under stable tension and positioned to receive the transferred pulp core from the forming section.
Constant tension, pre-glued surface, drum-synced conveying and automatic web guiding keep the layer stable.
Refines pulp boards into uniform fibers for absorbent core preparation.
A tooth-blade crusher with servo-controlled feeding processes fluff pulp into loose, even fibers ready for forming.
450 kg/h class capacity, alloy blades, variable-frequency speed control, vibration-isolated base and wide material compatibility.
Shapes loose fibers into a controlled core preform.
The forming drum connects directly to the crusher and works with the transfer wheel to pick up, compress and shape the pulp core.
Three-zone forming control, sweeper redistribution, hot-air assist, vacuum monitoring and stainless etched mesh support repeatable forming.
Applies super absorbent polymer onto the core according to the product structure.
The dosing unit meters powder SAP from the hopper and applies it evenly onto the core surface with automatic feeding support.
Adjustable dosage, servo-driven metering, low-level alarm and automatic refill improve process continuity.
Feeds the blue acquisition and distribution layer for core enhancement.
The ADL web is unwound smoothly and positioned for the next wrapping and core-combination sequence.
Constant tension, automatic web guiding, closed-loop tension control and line-synced feeding maintain material stability.
Adds and wraps the blue core layer onto the absorbent core.
The ADL layer is aligned and wrapped around the core so the absorbent structure reaches the intended acquisition format.
Automatic addition, roller wrapping, core-synced motion and controllable tension support accurate lamination.
Introduces the lower tissue layer for core lamination.
A bottom tissue web is unwound into position and synchronized with the moving core so the structure is ready for cutting and transfer.
Constant tension, automatic web guide and synchronized conveying help maintain layer alignment.
Cuts the absorbent core into its designed internal shape.
A rotary cutting unit with suction transfer trims the core according to the target contour before it enters the assembly stage.
Rotary knife and anvil structure, servo-driven motion, suction transfer and shape-defined cutting improve repeatability.
This stage turns the core into a finished sanitary napkin body. Bottom film, topsheet, three-piece structure and release paper are introduced in sequence, while embossing, perimeter sealing, outer cutting and 90-degree transfer prepare the product for individual wrapping.
Feeds the PE backsheet film that provides the waterproof bottom layer.
The bottom film is unwound under stable tension and delivered into the lamination section for body assembly.
Constant tension, automatic web guiding, closed-loop tension control and lamination-synced feeding protect web stability.
Feeds the topsheet nonwoven that forms the skin-contact surface.
The topsheet material is unwound and aligned for smooth integration with the core and bottom film.
Constant tension, automatic web guide and synchronized feeding support neat topsheet handling.
Builds the three-piece topsheet structure around the product body.
The side nonwoven is slit and guided to both sides of the center web, forming the three-piece topsheet arrangement used in the product design.
Pneumatic centerline slitting, independent AC drive and dual-side synchronized feeding help form the three-piece structure.
Heat-bonds and embosses the three-piece topsheet structure.
Heated rollers bond the side and center nonwoven layers into one integrated topsheet assembly.
Heated upper and lower rollers, adjustable width from 45–75 mm and servo-driven motion stabilize the embossing result.
Seals the perimeter and presses the designed product outline and pattern.
The sealing rollers apply heat and pressure to define the sanitary napkin body and complete edge bonding.
Heated rollers, shape-and-pattern embossing, closed-loop temperature control and servo drive support consistent sealing.
Cuts the assembled product into its final external shape.
A rotary blade and lower roller complete the final contour cut of each individual product.
Rotary knife structure, servo-driven cutting and clean-cut control support accurate final geometry.
Applies release paper to protect the adhesive on the product back side.
Release paper is fed and applied in register so the adhesive area remains protected for later consumer use.
Constant tension, precise positioning, automatic application and line-synced feeding improve placement accuracy.
Turns the product 90 degrees and connects it to the pouch film path.
A three-roll conversion unit changes the product direction and bonds it neatly onto the packaging film for the next stage.
Three-roll conversion, 90-degree transfer, neat film bonding and servo-driven motion support smooth handoff.
Use the full process view to compare core structure, material feeding, packaging requirements and the level of automation you need before final configuration.
This stage completes the single-pack downstream sequence. It introduces pouch film, performs two-fold motion, embosses and seals the pouch, supports label application and removes defective products so accepted pieces leave the line in an organized condition.
Feeds individual pouch film for downstream single-piece packaging.
Packaging film is unwound and positioned in sync with the line to receive the transferred product.
Constant tension, automatic web guide and synchronized feeding maintain pouch-film stability.
Folds the product in half on the pouch film before final sealing.
A dedicated folding unit with pouch positioning performs two-step folding to prepare the product for compact pouch packaging.
Dual folding mechanisms, pouch positioning, servo-driven motion and precise alignment support neat folding.
Embosses both pouch ends before final sealing.
Electrically heated rollers emboss the pouch to improve package shape, identification and visual finish.
Heated embossing rollers and servo control help stabilize embossing quality.
Seals the pouch and can add a tamper or easy-open label at the sealing position.
Heated sealing rollers close the pouch ends, slit the package into individual units and support automatic label feeding and application.
Heated sealing rollers, individual pouch slitting, automatic label transport and accurate label placement improve packaging completeness.
Conveys accepted products and removes unqualified pieces automatically.
After individual pouch cutting, a rejection unit identifies conditions such as start-up or material-splice defects and removes those packs with compressed-air action.
Compressed-air rejection, PLC-settable reject quantity, PLC plus manual control and automatic defect removal improve output organization.
The line combines web handling, metering, positioning, sealing, cutting and controlled rejection instead of relying only on one final inspection point.
Tension management, web guiding and synchronized feeding keep raw materials stable from start to finish.
Pulp crushing, drum forming and SAP dosing define the core structure and absorption capability.
Layer alignment during ADL addition, topsheet handling and release-paper application supports repeatable assembly.
Heated rollers, embossing units and cutting modules stabilize product geometry and package integrity.
Defect rejection and organized product discharge help accepted packs move cleanly into the next packing step.
Material widths, product sizes, embossing pattern, cut geometry, pouch style, label option and downstream packing interface should be treated as project-specific configuration items rather than universal values for every sanitary napkin line.
These questions help connect the illustrated process with real product, output and configuration decisions.
No. This page shows one complete reference configuration based on the uploaded process file. The final station arrangement can change with product structure, output target, packaging style and the level of automation required.
Typical inputs include fluff pulp, SAP, tissue, ADL or blue core material, topsheet nonwoven, PE backsheet film, release paper, adhesives and pouch film for individual packaging.
Yes. Product structure, embossing pattern, cutting geometry, release-paper format and pouch details should be confirmed during line configuration, because tooling and station setup depend on the target product.
Core formation, SAP metering, web-tension control, lamination alignment, perimeter sealing, cutting accuracy and rejection logic all influence product consistency across the line.
Prepare the target product type, size range, layer structure, output requirement, packing method, factory layout, voltage standard and destination market so the configuration can be matched to your project.
