Description
Technical field
The present invention relates to the method as described in the preamble according to claim 1, it is used for by nozzle surface glue, colorant (Pigmentstrich) or handled agent being coated to paper web face, paper/paper sheet breadth or other respective fiber breadth of motion.
The invention still further relates to the device that is used to realize said method as described in the preamble according to claim 19.
Background technology
In spraying process, inorganic agent is injected on paper web face, paper/paper sheet breadth or other respective fiber breadth of motion through nozzle.In the coating process by nozzle, the inorganic agent that must collect is to throw vaporificly and looses in environment.In fact, the shell structure through the nozzle place prevents that vaporific inorganic agent is diffused in the environment, thus in the application chamber of breadth opening, being coated with in sealing.Equally, prevent that the vaporific inorganic agent that in application chamber, forms is leaked in the environment, be pressed in the nozzle or in the injection stream as the inorganic agent that gathers and prevent that prevents its big drop.Inorganic agent is diffused into meeting contaminated equipment in the environment, and the inorganic agent drop that drops on the pending breadth may cause defective final products.
Some problem that in application chamber, sprays is that air flows in the application chamber through the inlet gap of application chamber with the paper web face together.This causes the pressure in the application chamber to begin to raise.Application chamber pressure raises, and surpasses the dynamic pressure that operation gets into the air layer that receives surface-limited of the breadth in the application chamber up to it.Therefore, air and vaporific inorganic agent can flow out from the position that is prone to reveal from the inlet gap of breadth and further.In addition, the paper web face also needs to tilt, and vaporific inorganic agent and air are discharged through the output gap of application chamber together.In order to stop this situation to take place, input side and the outlet side at breadth is provided with sealing device usually, stops vaporific inorganic agent and air from application chamber, to flow out.Also can the gas scraper be set in output edge, wherein, the same gas that sprays from nozzle opening normally air can stop vaporific inorganic agent from application chamber, to be revealed away.In addition, application chamber can be designed to, make its with press element for example roll gap keep directly contacting, wherein, the part of the roller at roll gap place formation application chamber wall, and breadth transports out from application chamber through roll gap.According to this scheme, vaporific inorganic agent and air are inappreciable through the amount in the output gap entering environment of application chamber.Yet in fact, this is very difficult, and it not is only to come " suction " paper web through the input gap that application chamber is sealed to.Along with the rising of pressure in the application chamber, vaporific inorganic agent and air can be leaked in the environment in the position that is prone to reveal.
Air flows in the application chamber also can cause problem at processing region, because inorganic agent must pass air layer by the kinetic energy of himself.Because the drop size of colorant (Strichmasse) is small, under higher jet velocity, has less relatively kinetic energy, this makes that passing air layer becomes difficult.In addition, the injection of the breadth of motion, inorganic agent and be connected with application chamber and the roller that rotates can produce disadvantageous eddy current and in application chamber, produce and flows backwards.Disadvantageous backflow can make vaporific inorganic agent carry back nozzle, and disperses in the inside of application chamber.
