Production Line Configuration: M: 390mm x 280mm, L: 450mm x 320mm, XL: 500mm x 320mm, XXL: 525mm x 330mm. Production Structure: Upper and lower toilet paper, SAP blended core or absorbent core, guide layer, water-repellent fabric (3D encasement), non-woven top layer, PE film, 3D rubber elastic, leg elastic, front waist sticker, elastic ear band (zero waste), S cut (front ear band). Drive System: The entire machine uses servo drive to ensure line speed accuracy and digital numbering; the front waist sticker and bottom film use servo positioning cutting to ensure pattern and phase alignment. Tension System: Equipped with tension unwinding system, constant tension control, and material storage mechanism, as well as material correction system. This constant tension system ensures stable feeding at full speed, reduces impact on material tension, and minimizes downtime. Safety System: The operating surface is equipped with safety protection devices, including emergency stop switches and safety signs. The rear drive is fitted with a safety pull cord, and the high-frequency fan uses soundproofing or noise reduction devices. Material Correction System: BST Corrector (optional)
