The SAP Sheet Making Machine is an industrial equipment designed for the continuous production of highly absorbent composite materials. Its core function is to combine fluff pulp, SAP superabsorbent polymer, and non-woven fabrics, airlaid paper, and other materials into a multi-layered structure with precise quantitative forming. It is widely used in the manufacturing of the core layer of sanitary products. This equipment is typically used as a front-end or core module in diaper making machine production systems, directly determining the thickness uniformity, gram weight accuracy, and absorption performance stability of the absorbent core layer. The entire machine utilizes fully automatic control logic, enabling automatic material metering, uniform spreading, precise compounding, and stable winding, meeting the needs of continuous, large-scale, and highly consistent production. It is suitable for industrial scenarios requiring high absorption performance and structural stability.

1、Accurate SAP Dosing

The machine controls single-layer SAP spreading within 20–120 g/m², with SAP spreading accuracy deviation controlled at ±2.5%. This precision helps reduce leakage risk, uneven absorption and unstable core weight caused by poor SAP distribution. For hygiene product factories, accurate dosing also helps control SAP consumption, which directly affects raw material cost in long-term production.

2、Continuous Speed Range

The normal working speed is 20–100 m/min, while the maximum design speed reaches 120 m/min. This gives manufacturers enough production flexibility for different absorbent sheet specifications, trial runs and continuous mass production. For buyers planning multi-shift operation, a stable speed range helps balance output demand and sheet quality without forcing the line to run at one fixed pace.

3、Five-Layer Core Forming

The machine supports a 5-layer composite design for materials such as fluff pulp, SAP, nonwoven fabric and airlaid paper. Interlayer displacement can be controlled within ≤1 mm, helping the finished SAP sheet avoid delamination or deformation during later processing. This structure is important when the absorbent core must remain stable before cutting, shaping or lamination.

4、Servo Metering System

The SAP spreading section uses servo metering and closed-loop control to keep material feeding more stable. Real-time control helps reduce SAP accumulation, local shortage and uneven spreading during continuous operation. For production engineers, this system makes gram weight adjustment more manageable when switching between absorbent sheet specifications.

5、Aligned Winding Control

The winding section supports a maximum winding diameter of Φ1200 mm and includes automatic tension adjustment with edge alignment. Tension fluctuation can be controlled within ±3%, reducing loose winding, edge collapse and feeding problems during storage or downstream production. A flatter roll helps buyers improve later connection with diaper or absorbent product lines. 

1、Baby Diaper Core Production

Baby diaper manufacturers need absorbent cores with stable thickness, uniform SAP distribution and reliable liquid retention. SAP Sheet Making Machine can produce high-absorbent composite sheets that are later fed into diaper production lines for shaping and lamination. This helps factories reduce leakage complaints and improve core consistency for mid-to-high-end diaper products.

2、Adult Incontinence Products

Adult care products require higher absorption capacity and stronger core structure than many baby diaper products. By increasing SAP spreading weight and using multi-layer lamination, the machine supports thicker and higher-gram-weight absorbent sheet solutions. This helps manufacturers develop adult incontinence products for long-duration use and higher absorbency requirements.

3、Sanitary Napkin Materials

Sanitary napkin core production requires accurate absorbent layer thickness and controlled gram weight distribution. The machine can adjust spreading parameters to produce SAP sheets with different absorption levels. For sanitary product factories, better distribution control helps avoid local thickening, uneven absorption and unstable product feel.

4、Medical Nursing Pads

Medical nursing pads need stable absorbent layers for hospital care, postoperative use and patient protection. SAP Sheet Making Machine can form uniform absorbent structures through low-deviation spreading and stable lamination. For medical absorbent product manufacturers, this supports more consistent pad performance and reduces quality variation in bulk supply.

5、Industrial Absorbent Sheets

Industrial absorbent sheet producers can use the machine for composite materials that need liquid absorption functions outside standard hygiene products. By changing raw material combinations and process parameters, buyers can develop absorbent layers for industrial pads, laboratory absorbent sheets or customized liquid-control materials. This gives factories more product development space beyond diaper core production.
