Web threading performance determines the success rate and efficiency of paper machine startup, tail threading and broken paper reconnection in high-speed production. Wet web and dry paper with poor threading performance are prone to tail tearing, lateral deviation, web sagging and threading breakage during automatic tail threading processes. Frequent threading failures lead to prolonged startup time, massive waste paper generation, unstable machine speed lifting and reduced overall production capacity. The core influencing factors include uneven tail tensile strength, insufficient edge toughness, excessive web flexibility, unstable surface friction and inconsistent moisture distribution at the paper tail. Most paper mills rely on manual auxiliary threading and tail reinforcement tape to improve efficiency, which increases labor costs, cannot adapt to fully unmanned paper machines, and brings hidden safety risks to on-site operation. Conventional strengthening agents improve overall strength but make the paper tail overly stiff, causing jamming during curved-section threading. Shandong Ludao Energy Technology Co., Ltd. develops dedicated paper threading performance enhancement solutions. By balancing tail tensile toughness, optimizing edge structural integrity and adjusting directional friction coefficient, we realize stable, straight and tear-free automatic web threading. The solution improves threading success rate, shortens startup and recovery time after paper breakage, reduces manual intervention, and supports fully automatic, high-efficiency unmanned operation of modern paper machines.
