Production Line Configuration: Product Specifications: M, L, XL, XXL. Product Structure: Upper and lower toilet paper, cotton core (SAP blend) or absorbent core, flow guide layer, waterproof fabric (3D cuff), non-woven surface layer, PE film, 3D elastic band, leg elastic band, front waist sticker, elastic ear band (zero waste), S-cut (front ear band). Control System: PLC control with a touch screen human-machine interface and a high-definition TV monitor. Transmission System: The entire machine uses servo transmission to ensure line speed accuracy and digital numbering; the front waist sticker and bottom film use servo positioning cutting to ensure the pattern and phase alignment. Tension System: Equipped with tension unwinding system, constant tension control, and material storage mechanism, as well as a material bias correction system. This constant tension system ensures stable material feeding at full speed, reduces the impact on material tension, and decreases the number of machine stops. Safety System: The operating surface is equipped with safety guards, emergency stop switches, and safety signs. The rear transmission is fitted with a safety pull cord, and the high-frequency fan uses soundproofing or noise reduction devices. Bias Correction System: BST bias corrector.
