Basic Concept and Latest Headbox Design

Abstract

The function of headbox is defined as yashi Engineering Works,stock and pours it on the wire with certain thickness and speedpo The function typically demanded on headbox is as follows.

・Makes proper stock dispersion and supplies the stable stock flow to the slice section.

・Jets the uniform stock flow free from streak and diagonal flow in cross machine direction.

・Maintains the stable slice section not influenced by the pressure and temperature variation.

・Keeps cleanness inside and easy for maintenance.

On the other hand, high functional devices such as dilution profiling system, headbox sheet, and evener rolls according to the client, the other hand, high functional devices such as dilution profiling system, headbox sheet, and evper quality target is very important engineering work. Evaluation of headbox is very much concerned with the paper quality such as basis weight profile, formation and properties.

This reports the latest dilution type profile system as well as the basic function and mechanism of our headbox.
