Definitions
- the invention relates to a device for coating paper or board webs with two axially parallel juxtaposed rollers which form a gap through which the paper or board web is guided, and with an application and metering system for at least one of the rollers for applying a metered Film of coating material on the surface thereof, wherein the application and dosing system includes an open to the roller application chamber having a supply for coating material and is closed on the roll outlet side of the dosing.
- Devices of the generic type are used for finishing paper or board webs with glue, starch or pigment inks and are referred to as so-called film presses.
- the coating material is first applied as a metered film to one or both rollers by the application and metering system associated with a roller, and then it is delivered to the web in the coating gap between the two rollers.
- the coating material not delivered to the web in the coating gap remains on the roll surface and is transported back to the application and metering system. Usually there is an overflow gap on the inlet side, from which the excess coating material emerges against the direction of rotation of the roller. The emerging excess coating material usually rinses off the recycled coating material. It is thus collected with this in a contract tray and returned to the application chamber.
- a coating device of the generic type is in the DE 10 2004 039162 A1 described.
- impurities for example waste paper fibers
- the impurities are taken up in the transfer nip from the roll with the remaining coating material and transported to the application and metering system. Often they stick to the rollers and then cause problems at the metering element closing the chamber, for example by the impurities clogging the profiles of a profiled metering rod used as metering element.
- the moistening with a cleaning liquid has the disadvantage that the coating material is scraped off together with the cleaning liquid. Returning the scraped liquid mixture to the coating circuit is not possible because the mixture is too dilute even when using pure water as the cleaning liquid. Therefore, it is forced to dispose of the scraped, cleaning liquid-containing coating material. In addition, a separate cleaning device is structurally very expensive. In many film presses, the required space is not available.
- the invention is therefore based on the object to improve a device of the generic type so that contaminants can be removed without the use of a separate cleaning fluid and without additional space from the roll surface.
- This object is achieved in that at a distance from the dosing of the dosing a scraper is arranged, which extends across the width of the application chamber and as stabbing scraper against the roller can be adjusted, wherein coating material can be supplied both before and behind the scraper against the roll surface is.

- the openings 23 are arranged in the resilient element, in the example in the spring plate 33. Coating material flows from the chamber 11 through the openings 23 against the roller 2 and is discharged via the roller 2 facing side of the spring plate 33 together with the scraped impurities and the scraped air.
- coating material flows from the supply 12 into the areas in front of the scraper 22 and behind the scraper 22.
- the material guided in front of the scraper 22 flows counter to the direction of rotation of the roller 2, taking with it the scrapes scrapped by the scraper 22.
- the penetration of air is largely prevented by the seal on the inlet side.
- the scraper 22 also serves as a seal on the inlet side of the chamber 11.
- the supply of coating material in front of the scraper 22 takes place in such a way that the material is guided out of the chamber against the roller 2 through openings 23.
- the effluent is collected in the tub 22 and then filtered to remove the contaminants. Thereafter, it is returned together with new coating material via the feed 12 in the application chamber 11.
- the coating material behind the scraper 22 is again doctored off from the dosing element 13 to the desired film thickness from the roll surface 2.
- the remaining on the roller 2 film is discharged except for the entrained by the rollers 1, 2 rest with the impurities in the nip 5 to the paper web 6.
