Abstract: A device designed for coating a material web with a coating medium includes a coater, a metering/smoothing device positioned downstream of the coater in the direction of feed of the material web, at a certain distance from the coater, and a support roll around which the material web is guided. Moreover, the material web is guided around the support roll only in the area of the metering/smoothing device, and it traverses essentially in a straight line between the coater and the support roll. In accordance to a first aspect of this invention, a support arrangement supports the material web in the straight web section between the coater and the support roll. In accordance to a second aspect of this invention, devices are provided which stabilize the material web in the area where the web traverses in a straight line.

Abstract: A method of producing paper webs coated on both sides includes the following steps: a) indirectly applying a liquid onto the paper web by passing the web through at least one nip formed by a roll and a counterelement, whereafter the web is dried; b) next, directly applying coating mixture at surplus only on one side of the web, whereafter the surplus coating mixture is removed again by use of a doctor element, the web being dried again thereafter; and c) lastly, directly applying coating mixture at surplus only on the other web side, whereafter the surplus coating mixture is removed by use of a doctor, whereafter the web is dried again. In the indirect application of liquid in the nip, or in the nips, either coating mixture to produce so-called MWC papers or a sizing suspension to produce so-called LWC papers is selectively applied.

Abstract: An apparatus applies a liquid or viscid coating medium onto a moving material web, especially one made of paper or cardboard. A coating mechanism first applies the coating medium onto an applicator element or an applicator roll, which subsequently transfers the coating medium at a coating location onto the material web in the form of a coating layer. Furthermore, if so desired, a doctoring device can be positioned at a doctor station, adjacent to the coating location, on the downstream side relative to the movement of the material web for the purpose of smoothing and/or metering the coating. The coating apparatus incorporates an apparatus for the generation and/or supplying of a fluid, preferably steam. This apparatus is positioned adjacent to the coating location or to the doctor station on the downstream side relative to the movement L of the material web.

Abstract: The invention relates to a method for directly or indirectly applying a liquid or pasty application medium (2) onto one or both sides of a continuous surface (4), wherein the application medium (2) is applied to the surface (4) in a plurality of single application regions by means of a plurality of single application nozzles (12) spaced apart from one another side by side and/or in succession in the direction of width (B) and/or longitudinal direction of the surface (4) and clearly distanced (D) from the surface (4), the application medium (2) emerging from each of these nozzles, wherein adjacent single application regions each intersect (U) at least in part in their respective edge regions, causing a layer of application medium to be produced across substantially the entire width (B) of the surface (4) to be coated. The invention also relates to an apparatus for performing this method.

Abstract: A method and apparatus for coating a traveling layer of material, in particular paper and/or cardboard. An applicator implement applies a predetermined and proper amount of a liquid or pasty medium onto an outer surface of a first rotating applicator roller which in turn transfers the liquid or pasty medium onto a first side of the moving layer of material just as it is moving through a press nip. A second layer of coating medium is applied indirectly with a second applicator implement onto an outer surface of a second rotating applicator roller from where it is transferred onto the previously coated side of the moving material layer while the first coat of coating medium is still wet.

Abstract: A system for selective treatment of a traveling web, preferably of paper or cardboard, by surface treatment or impregnation in which at least one coater is in the case of web treatment arranged after a dryer group for treatment of the one side of web. At least one further coater for treatment of the other side of the web is arranged before a further dryer group. Noncontact web deflectors are arranged after the coaters and noncontact dryers can be installed retroactively in existing dryer sections.

Abstract: In a method for direct or indirect application of a liquid or pasty medium onto a traveling material web, notably of paper or cardboard, where during the application the cross profile (length profile) of the medium is modified under control and thereafter, in the direction of travel, the length profile (cross profile) of the previously applied medium is modified under control. Control of the cross profile and control of the length profile of the applied medium occur separately from one another in automatic control loops based on measurements of the applied profile. In addition is a pertaining apparatus with an applicator, an equalizer, a pertaining cross profile control loop, and a pertaining length profile control loop.

Abstract: In a single wire dryer group, a paper web travels on one side of a support belt over a first dryer cylinder, then over a guide roll, then over a second dryer cylinder moving through the dryer group. A pocket is defined between the two adjacent dryer cylinders and the guide roll between them. To develop a vacuum within the pocket in the vicinity of the outer surface of the first dryer cylinder, there is a sealing ledge at the support belt at the first dryer cylinder. The sealing ledge is fastened to a sealing ledge support. An air guide surface on the side of the sealing ledge support away from the pocket is curved first in a direction toward the bottom of the pocket and then away from the pocket around axes above the air guide surface. Toward the second cylinder, the sealing ledge support defines an air ejector nozzle. A first air flow induced on the first dryer cylinder is deflected upward around and past the ejector nozzle by the curvature of the air guide surface.
