Air-Cushion Headbox For Paper Machine

High-Performance Air-Cushion Headbox For Paper Mills

The headbox plays a critical role in the approach flow system of a paper machine. It is responsible for the core tasks of uniformly distributing the stock across the machine width, generating a stable and controllable jet onto the forming fabric, ensuring even fiber dispersion, and preventing flocculation. Thanks to the unique air-cushion buffering mechanism and proven engineering track record, air-cushion headboxes have become the preferred choice for many paper mills.

Air-Cushion Headbox Features

Stable stock flow and uniform sheet formation: An air cushion absorbs pump pressure pulsations, reducing fluctuations in basis weight (machine direction) and minimizing defects caused by air bubbles; this results in fewer web breaks and higher production efficiency.

Precise cross-direction (CD) basis weight control: Uniform stock distribution combined with micro-adjustments of the slice lip ensures stable basis weight across the entire width and reduces trim waste.

Excellent fiber dispersion: Dual evener rolls generate controlled micro-turbulence, preventing fiber flocculation and ensuring superior sheet uniformity and strength.

Hassle-free automatic control: Automatic regulation of total pressure, stock level, and jet-to-wire speed ratio facilitates rapid grade changes and minimizes batch-to-batch variation.

Robust and easy to maintain: With fewer moving parts, the system accommodates both wood pulp and recycled pulp; it is simple to maintain and supports long periods of continuous operation.

Versatile application: Suitable for producing cultural paper, tissue paper, and packaging paper, eliminating the need to replace the entire machine when switching product grades in the future.

For paper mills specializing in cultural paper, tissue paper, and packaging paper, selecting an air-cushion headbox with a well-balanced configuration lays the most solid foundation for product quality. Our email: leizhanmachines@gmail.com
