Definitions
- the invention relates to a method and a device for curtain coating according to the preamble of claim 1 and claim 11.
- the coating When coating a paper or board web with a curtain applicator, the coating should be applied as evenly as possible over the entire web width in order to make good use of the advantages of contactless application.
- the application thickness must be as constant as possible over the entire web surface. The basic prerequisite for this is a uniform distribution of the coating over the outlet width with regard to the volume flow and the speed.
- the Curtain Coater can be used with a slot die or a cascade die.
- a slot die slot-fed die
- the curtain applicators with a slot nozzle are for example off DE 197 16 647 A1 and DE 10 2005 017 547 A1 known.
- the cascade nozzles (Slide-Fed Die) are used in the multilayer web coating.
- the coating material first flows from a distribution chamber upwards to the outlet gap. From the exit slit, the coating material flows on an inclined plane, where it is superimposed with the coating slips of the upper layers and then passed to the nozzle lip. Only at the trailing edge of the nozzle lip forms a curtain.
- the cascade nozzles are described for example in WO 01/54828 A1 and WO 2005/024133 A1 ,
- the curtain is accelerated in free fall due to gravity. As the distance from the exit edge of the nozzle increases, the curtain is drawn from the edges to the center by the action of gravity and surface tension. The width of the curtain is thereby narrower. In order to prevent the curtain from contracting, the curtain is guided by means of edge guiding elements at the edges.
- the width of the curtain can be greater than the web width in a so-called overboard mode.
- values of about 100 to 200 mm may be mentioned here.
- a simple embodiment of the edge guide elements is generally sufficient in order to ensure a high uniformity of the distribution of the coating compound in the edge region.
- a disadvantage is the adhesion of coating material to the underside of the paper or board web, as a result of which undesired contamination in the area of the coating zone occurs.
- the width of the curtain is less than or equal to the web width.
- the coating color in the edge area and in the middle must be distributed very evenly over the width of the web. It is important that the curtain hits the moving paper or board web at the same speed throughout the impact zone. Otherwise, there would be problems with the coating of the paper or board web in the form of edge beads and not dried edges.
- edge guide elements for the inboard driving style are described for example in EP 0 907 103 A1 .
- EP 1 458 493 A1 and WO 02/081103 A1 are described for example in EP 0 907 103 A1 .
- EP 2 067 531 A2 EP 1 458 493 A1 and WO 02/081103 A1 ,
- EP 0 737 521 A2 describes a method and apparatus for reducing curtain screen disturbances.
- the curtain edge is separated by a free jet of a separating liquid. Since the free jet in the puncture area also withdraws liquid from the curtain, no bead-shaped edge forms on the base. It is therefore even possible to uniformly thick coat to the outermost edge of the pad.
- the water jet for a separation process is used, as is known for example from the water jet cutting of solids.
- the disadvantage is that coating compounds with a high elasticity can not be separated by such water jet cutting.
- the separating elements described above are therefore to be used in order to avoid the formation of a bead in the edge region, which otherwise results in that comparatively much coating color is applied to the edge. This would have As a result, the guide rollers and Airturns become soiled with paint. The bead of paint can be dried badly. The individual layers of paper stick together on the spool. Due to the disadvantageous adhesion of the coating color to the separating elements, such aids are maintenance-intensive and susceptible to wear.
- Out DE 10 2005 036 667 A1 is a method and a curtain applicator for applying liquid to pasty application media on a running paper, board or other fibrous web in their production and / or processing known, the curtain applicator a substantially gravity-related moving, free-falling order medium curtain directly discharges to the surface of the moving fibrous web and wherein the curtain impinges in a line of impact either on a free web or on a train, the fibrous web supported by a support member area.
- a fluid delivery device is provided, which is arranged such that the fluid jets emitted by the latter wet the front edges of the fibrous web with the fluid before the impact line of the application medium curtain. As a result, the edge wetted with fluid remains uncoated during subsequent coating.
- a fluid delivery device can also be provided obliquely to the fibrous web and that at an angle of up to 65 ° employed employees. Contrary to the direction of the web, the fluid jets cut through the curtain in the edge area of the web and wet the web front faces at one point before the curtain reaches the web surface at the point of impact.
- This provides a method and apparatus for curtain coating a moving paper or board web in which the free falling curtain is separated into a curtain center portion and at least one curtain edge using a separator having a free jet of release liquid.
- the curtain is stretched at the interface on an inner side and compressed on an outer side, wherein the inside and outside are related to the curtain middle part.
- the coating is thus distributed on the inside over a larger area.
- the layer thickness can consequently be reduced in the edge region and bead formation in the edge region on the paper or board web can be minimized. This applies equally to coatings of lower or higher viscosity, which can therefore be applied more uniformly. Function bars of selectable type can thus be applied improved with a small amount of coating, which also results in a cost advantage.
- the free jet cuts the curtain preferably from behind. At the interface behind the curtain then forms a meniscus-like curvature with the aforementioned advantages.
- a dispenser for forming a curtain falling on a coating side of the paper or board web in free fall may form a curtain having a width that is less than or greater than the width of the moving paper or board web and / or its backing ,
- the subject invention is in overboard driving as well as inboard driving applicable.
- the separation of the curtain can be made by selecting the spatial position of the penetration area so that the entrained curtain edge forwarded and coated the curtain middle part in the manner of inboard driving the paper or board web, without the bead on Edge of the coating, which is applied through the curtain middle part on the paper or board web.
- the overboard driving style can be converted into an in-board driving style, wherein at the edge of the coating by the curtain middle part no bead is formed or at least the bead formation is minimized.
