Underfeed Rewinder in Pulp and Paper Machinery
The underfeed rewinder is a robust paper mill machine specifically designed for slitting and rewinding heavy paper rolls with basis weights suitable for packaging and industrial applications. This pulp and paper machinery is powered by a main supporting roll motor along with auxiliary motors for the slitting mechanism, oil pump, and suction fan, all coordinated through an advanced control system that ensures smooth and precise operation.

The underfeed rewinder is equipped with a hydraulic paper pressing device that automatically adjusts pressure as the roll diameter increases, maintaining consistent roll hardness throughout the rewinding cycle. The underfeed rewinder features dynamic balancing of all rotating components to ensure smooth, vibration-free operation at maximum speeds. The underfeed rewinder incorporates a double drive reducer system that ensures balanced power distribution across both supporting rolls, extending equipment life and reducing maintenance requirements.
