In the pressure area being formed between face, and air or mist that convergence surface is also configured to for preventing process medium are narrow by entrance
Groove flows out.
In the configuration structure of prior art, the usual phase of entrance opening/entry slot of application room/jet chamber/treatment region
To narrower.In practice, due to too many air may be made to flow in treatment region, so opening can not be too wide, but opening
Width must be enough to providing enough spaces between web and the edge surface of opening.In the case that space is too little, width
Material is by the edge of contact openings and against surface scraping, and leads to the vibration of web.
The scraping on web abutment edges surface leads to the abrasion of this surface and web, and laying dust.The ash being led to by scraping
Dirt and dirt can cause problem in treatment region, and hardly possible so that configuration structure is operated for a long time.The scraping of web

Mouth is used as preventer, and this suction nozzle is located at the outlet side of protective cover, and that is, pending fiber web is directed out treatment region
Side.Suction nozzle makes air and mist remove to mist separator via suction channel and leave from pumping equipment further.
In entrance side, typically prevent mist from spreading from treatment region at least in part by the air-flow that the fiber web passing through provides.It is also known that,
Preventer is located at the edge of the protective cover as near as possible with fiber web, but in this way it is impossible to realize controlling completely
Mist processed.Removing and separate the pumping equipment needed for mist needs substantial amounts of air to form sufficiently fast flowing, thus always by mist
Remove to separator, so that pumping equipment keeps cleaning.Mist separator is typically very expensive and considerably complicated equipment, and
In some cases, the passage of its own and the space needed for device are likely to lead to space problem.
