Air Cushion type headbox can increase the sizing pressure to meet the requirements of medium and high speed paper machines.The headbox consists of square taper tube device, evener roll device, top lip plate adjusting device, box body,control system, spraying device, air path system, etc.The headbox is designed with customer performance parameters, which can ensure work performance.

1.Headbox is used for sizing in fourdrinier wire section of paper making machine for producing cardboard paper, corrugated base paper, writing and printing paper, offset paper and so on.

2.Applicable speed range: 160-480m/min

1.The speed of the web pulp can be adjusted by the air pressure above the pulp surface in the compressed air conditioning box (the pulp level remains unchanged, and the appropriate pulp head can be obtained by changing the air cushion head).
2.Using square cone tube and porous plate as the distributor, flat bottomed weir pool has low slurry level and fast flow rate.

3.Using two homogenate mixture as rectifying element, the homogenizer wheel at the outlet of orifice plate mainly acts as energy dissipation and rectification of jet flow from orifice plate, while the homogenizer rod in front of convergence zone of weir plate mainly acts as rectification.
4.Equipped with a front wall overflow device to stabilize slurry position and remove foam.
5.Combined lip plate was used.

1.It can be used to produce the paper sheet with uniform and stable quantity, and there is no longitudinal flow on the web;
2.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;
3.Easy to keep the box clean;
4.The ratio of jet to wire speed is controllable.
