Product Description

Description headbox:

The purpose of headbox is to take the stock delivered by the feed pump and transform the stock flow into an even, rectangular discharge equal in width to the paper machine and at a uniform velocity, consistency and pressure in the machine direction. Since the formation and uniformity of the final paper product are dependent on the even dispersion of fibers and fillers, the design and the operation of the headbox system are absolutely critical to a successful paper making.

1. Spread the stock evenly along the width of the paper machine.
2. Accelerate the stock up to the machine operating speed.
3. Suspend the pulp fibers throughout the outgoing slurry.
