The printing machine's head box  is an integral part of the printing process. Without a good headbox, your printing machine will produce inferior-quality prints. Fortunately, there are many ways to improve the performance of your head box. Here are some of them:

First, the head box is used to control the consistency of the paper. Most paper grades are produced with less consistency than others. Longer fibres require less consistency than short ones. Higher consistency increases fibre orientation in x-y direction, while lower consistency promotes calliper, tensile, and strength properties. This is crucial for printing because higher consistency results in better formation. Even with a low consistency, many sheet properties continue to improve, though this is impractical.

Similarly, a good head box prevents unwanted material from interfering with the quality of the print. For example, the head box in a printing machine should avoid any excess pulp. Moreover, the paper machine's furnish box is responsible for dispensing pulp into the papermaking process. It should be easy to access and clean. However, there are many possible pitfalls. Incorrectly-cleaned paper can cause an inferior print.

Another major problem with the head box of a printing machine is the cockle finish of the paper. High bulk sheets have more than a dozen sheets per inch, whereas low bulk sheets contain fewer than one hundred. High bulk sheets are smooth and durable, but they have a tendency to have more wrinkles than low-quality ones. A high-speed machine can print 300 lines a minute and even more. There are also some other issues that you should look out for when you're using a printing machine.

Paper machine heads have a roll that controls the flow irregularities. It creates turbulence in the stream of paper and keeps the fiber dispersed up to the opening of the slice. The headbox roll is also known as a holey roll or hollow perforated roll, and it is normally two to four centimeters in diameter. The head box roll has several purposes. Among them are to prevent paper from buckling.

Another important part of a head box is its slice. A headbox slice has a full width nozzle and an adjustable opening. The distance between two lips controls the speed of the stock jet. A low-speed machine can have fibres that get pulled out of the paper. If the spool is too wide, it can lead to paper that falls into the wrong channel. Changing the headbox's slice can help reduce the buckling of the stock, which will affect its quality.

Paper cleaning is another important aspect. The cleaner the paper, the less ink is needed. The slitter wheels on the folder make this process easier. Those wheels cut the printed sheets, but make sure that the edges are smooth. Similarly, the head box of printing machine heads have many cleaning functions to help them perform their jobs. They also have a rotary cutter and a slitter. These three components are crucial to the process of printing.
