Definitions

the invention relates to a treatment device for Material webs in which a treatment chamber has a treatment roller and has two deflecting rollers, which Material web for partially wrapping around the treatment roller redirect.
Material webs often have to be closed in a Treatment chamber are treated. That is for example in the case of fluorinators which serve this purpose can, plastic material webs by action make it wettable by fluorine.
Another, essential one Use case for such treatment devices the coating of foils, for example by vapor deposition with a metal.
DE 42 07 526 C2 As an example of the state of the Technology is referred to DE 42 07 526 C2.
This steaming takes place under vacuum inside the treatment chamber.
the incoming and outgoing material web sealing through the wall of the treatment chamber be guided so that no air into the treatment chamber can occur. Is it the treatment chamber around a fluorination chamber, it must face the outside be tight so that no fluorine is harmful to the environment can penetrate to the outside.
the treatment roller protrudes with part of its outer surface out of the treatment chamber. Therefore it is necessary between the wall of the treatment chamber and the Treatment roller to provide sealant. That prepares Difficulties when the web of material to be treated Thickness fluctuations and are not elastically deformable are.
the treatment roller is often also heated and based on the treatment process, that you’re having trouble sealing up.
the invention is based on the problem of a treatment device of the type mentioned at the beginning that reliable sealing of the treatment chamber with fluctuations in the thickness of the material web if possible little effort is possible.
the treatment roller needs not to be sealed.
the treatment roller can therefore free for the task of treating the material web be designed and perform diverse tasks, which are often not or only difficult with the requirement a seal must be agreed.
sealing takes place instead of to the treatment roller Deflection rollers out.
the deflecting rollers cause them to fluctuate in thickness can dodge, so that they also at non-elastic material webs always with optimal pressure lie against the material web and the sealing surface.
the treatment chamber is special compared to its surroundings reliably sealed off when the guide rollers in a prechamber are arranged, which by an intermediate wall is separated from the treatment chamber, and if the partition for each deflecting roller one Breakthrough has which on both sides of the respective Deflection roller by a in the longitudinal direction of the deflection roller running seal is sealed, which the sealing surfaces form.
a particularly good seal can be achieved if according to another embodiment, a sealing surface by placing the respective deflection roller on the treatment roller is formed. This can avoid that it is between the web of material and each Sealing surface comes to a sliding friction. If realize the largest possible treatment area then you can of course also use the treatment roller arrange at a considerable distance from the deflection rollers, so the web of material within the treatment chamber runs freely over a correspondingly large area and on the back only in the area of the treatment roller based on this.
a treatment gas is to be treated, then reached you get a particularly intense treatment when close to the Infeed side of the material web in the treatment chamber a blowing nozzle directed against the incoming material web is arranged for treatment gas.
blowing nozzle for the exclusive supply of the treatment gas is formed via a gas circulation line.
a transfer of treatment gas into the environment exclude themselves particularly safely by the fact that in the antechamber near a web entry opening and near one Web outlet opening each arranged a gas suction is.
the treatment device according to the invention is particularly advantageous can be used when used for fluorine treatment is formed by material webs.
the invention permits various embodiments. To further clarify its basic principle is one of which is shown in the drawing and is shown below described.
the drawing shows a vertical section through a Treatment device, which in a housing 1 Treatment chamber 2 and one of these through an intermediate wall 4 divided prechamber 3 has.
a treatment roller 5 is rotatably arranged, a material web 6 via a deflection roller 7 is supplied and from which the material web 6 via a further deflection roller 8 expires.
These deflecting rollers 7, 8 project in each case with a partial area of their lateral surface the treatment chamber 2 into it.
the Partition 4 two openings 9, 10, which of Seals 11, 12, 13, 14 are bordered, respectively Form sealing surfaces 15, 16.
the two deflection rollers 7, 8 are each one pneumatic pressure cylinder 17, 18 in the direction of the axis of rotation 23 of the treatment roller 5 movable and in the direction the treatment roller 5 biased. Thereby lie with prestress against the sealing surfaces 15, 16.
seals 11, 12, 13, 14 can also be elastic in this way be designed so that the deflection rollers 7, 8 over the material web 6 deflected by them with pretension Support on the treatment roller 5. Then it comes there to form a sealing surface 19 and thus a seal, so the seals 12, 13 their meaning to lose.
Another important feature of the invention is one Blow nozzle 20, which on the inlet side of the housing 1st is arranged in the treatment chamber 2 and the treatment gas immediately after the material web 6 has entered blows against the material web 6.
a gas suction 21, 22 In the antechamber 3 you can see near the inlet side or outlet side of the material web 6 a gas suction 21, 22, through the possibly reaching the antechamber 3 Treatment gas is sucked off.
the gas extraction 21, 22 is set such that in the antechamber 3 there is always low vacuum and therefore constantly Outside air flows into the pre-chamber 3 and a reverse Gas flow is excluded.
