When it comes to the production of paper, you may wonder how large quantities of paper are continuously produced without interruption. This is made possible through the use of a paper continuous machine. In this article, we will provide an overview of how the paper continuous machine works, shedding light on its various components and processes.

What is a paper continuous machine?

A paper continuous machine is a high-speed machine used in the paper manufacturing industry to produce continuous rolls of paper. It operates by converting pulp, which is a mixture of water and cellulose fibers, into paper sheets.

What are the main components of a paper continuous machine?

A paper continuous machine consists of several key components:

  • Headbox: This is where the pulp mixture is evenly distributed onto a moving wire mesh.
  • Wire Section: The wire mesh carries the pulp through a series of rolls that extract water and help the fibers bond together.
  • Press Section: In this section, the partially formed paper sheet passes through more rolls, squeezing out additional water.
  • Drying Section: The paper sheet enters this section and passes through a series of heated rolls or dryers, where the remaining water is evaporated.
  • Calender Section: The dried paper sheet undergoes additional pressing between heavy rolls to provide a smooth finish.
  • Reel Section: Finally, the continuous paper sheet is wound onto a large reel, ready to be used or further processed.

How does a paper continuous machine work?

The paper continuous machine works in the following sequence:

  1. The pulp mixture is supplied from a storage tank or directly from the pulp mill to the headbox.
  2. The headbox sprays the pulp mixture uniformly onto the wire mesh, forming a layer of fibers.
  3. The wire mesh, along with the wet fibers, moves through various rolls in the wire and press sections, allowing water to drain out and fibers to bond.
  4. The partially formed paper sheet then enters the drying section, where it passes through heated rolls or dryers, evaporating the remaining water.
  5. After drying, the paper enters the calender section, where it undergoes additional pressing between heavy rolls to enhance its surface smoothness.
  6. Finally, the continuous paper sheet is wound onto a large reel in the reel section, ensuring it stays intact and ready for further processing or use.

The paper continuous machine plays a crucial role in the paper manufacturing industry, allowing for the uninterrupted production of continuous rolls of paper. Its various components and processes work together to convert pulp into high-quality paper sheets. Understanding how this machine operates provides valuable insights into the complex yet fascinating world of paper production.
