Head Box is the heart of paper machine. Its function is to supply even and stable pulp flow to the wire section of paper machine. Every head box design has its special technical conditions, which is different according to the kind of stock, speed, flow and so on.
Our company design and manufacture head box according to the actual production of the customer, then calculation and design accurately under the help of computer.
Advantage
It can be used to produce the paper sheet with uniform and stable quantity, and there is no longitudinal flow on the web;
The lip area of headbox should not be affected by pressure, temperature and opening degree of the lip to ensure the uniform distribution of the width;
Easy to keep the box clean;
The ratio of jet to wire speed is controllable.
Application
Used for sizing in fourdrinier wire section of paper making machine for producing the cardboard paper, corrugated base paper, writing and printing paper, offset paper and so on.
Requirements for good headbox
