Production Line Configuration: M: 380mm x 210mm, L: 420mm x 220mm, XL: 480mm x 220mm, XXL: 520mm x 220mm. Production Structure: Top and bottom toilet paper, cotton core (SAP blended) or absorbent core, drainage layer, waterproof fabric (three-dimensional guard), non-woven top layer, PE film, three-dimensional rubber elastic, leg rubber elastic, front waist sticker, elastic ear band (zero waste), S-cut (front ear band). Control System (co*ol System): PLC control with a touch screen human-machine interface, equipped with a high-definition TV monitor. Drive System: Whole machine drive uses servo transmission to ensure line speed accuracy and digital numbering; front waist sticker and bottom film use servo positioning cutting to ensure pattern and phase consistency. Tension System: Equipped with tension unwinding system, constant tension control, and material storage mechanism, material bias correction system. This constant tension system ensures stable feeding at full speed, reduces the impact on material tension, and minimizes downtime. Safety System: The operating surface is equipped with safety protection devices, emergency stop switches, and safety signs. The rear drive has a safety pull cord, and high-frequency fans use soundproofing or noise reduction devices. Bias Correction System: BST Bias Corrector (optional)
