3400 mm Overfeed Rewinder in Pulp and Paper Machinery
The superfeed rewinder is a precision paper mill equipment solution designed for the precise slitting and rewinding of paper rolls in the finishing stages of paper production. This paper mill equipment consists of a series of precisely designed components that work seamlessly together: a robust feed frame with lateral and longitudinal displacement mechanisms for precise roll positioning; a pneumatic braking system with dual air ducts and a circulating water cooling system to apply controllable tension to the paper web during rewinding; and upper, middle, and lower guide rollers to ensure the paper enters the slitting system at a constant angle while flattening the paper.
This rewinder comprises the following main components: multi-segment arc-shaped spreading rolls installed between guide rolls to evenly spread the paper web to both sides before slitting; a precision slitting system including an upper circular blade with hardened steel cutting edges and a lower cutter roll with multiple annular cutting edges; a shaftless winding device with a sliding support frame and clamping center to securely hold the paper core during rewinding; a hydraulic lifting system to control the load in the pressure zone between the paper roll and the lower roll; and a paper pusher with hydraulic cylinders to eject the finished paper roll from the machine. This complete pulp and paper machinery configuration also includes a powerful main drive system, a dedicated hydraulic station, and an intuitive operating console, making this top-feed rewinder an indispensable piece of equipment in any complete paper production line producing corrugated paper, tube paper, T-paper, and kraft paper.
The overfeed rewinder delivers exceptional performance advantages for modern paper finishing operations. This overfeed rewinder features a top paper feed design that ensures smooth and reliable paper threading, minimizing web breaks during operation. The overfeed rewinder incorporates a robust frame structure with box-type front and rear frames, providing excellent rigidity and strength for safe operation at high speeds. The overfeed rewinder’s pneumatic braking system allows precise tension control through adjustable air pressure, ensuring consistent paper tension throughout the rewinding process as the roll diameter changes.
The overfeed rewinder is equipped with a hydraulic paper pressing system that continuously adjusts oil pressure as the paper roll diameter increases, guaranteeing uniform tightness from the core to the outer layers of the finished roll. The overfeed rewinder also features a frequency conversion drive system that delivers stable performance, convenient operation, and easy maintenance, while the dynamic balancing of bottom rollers at 800 m/min ensures smooth, vibration-free operation even at maximum speeds.
