A device for applying a liquid to pasty medium to a moving surface, the moving surface in the case of direct application being the surface of a paper, board or other fibrous web. In the case of indirect application the moving surface being the surface of a transfer element which transfers the application medium to the surface of the fibrous web. The device includes an applicator for applying the medium and a doctor device arranged downstream in the running direction of the moving surface for doctoring off and/or equalizing the medium applied to the moving surface. In order to collect excess medium that has not remained on the moving surface and/or has not reached the latter, a flexible collecting part covering the interspace between applicator and doctor device is provided, which extends transversely with respect to the running direction of the moving surface and parallel to the applicator and the doctor device.

Application device

A roller is provided for use in coating machines. The roller directly or indirectly applies a liquid or pasty medium to one or both sides of a running web of material, especially one made of paper or paperboard. The roller includes a core whose outer casing is provided with a covering made of an elastomeric material. The covering is designed such that it can be compressed.

Roller provided for use in coating machines

An apparatus for direct or indirect application of a liquid or pasty medium onto a traveling material web includes at least one rotatable backing roll wrapped in part by the material web and supporting a side of the material web near the backing roll. The backing roll surface and the material web form a cuneiformly tapering entrance gore and an exit gore. At least one applicator opposes the backing roll and coats a side of the material web away from the backing roll with the medium, and/or further treats the coated material web side. A boundary layer stripper is arranged, in relation to the direction of rotation of the backing roll, before the applicator. The boundary layer stripper removes an air boundary layer entrained by the backing roll and/or the material web. The air boundary layer stripper is arranged in the entrance gore between the backing roll surface and the side of the material web near the backing roll.

Apparatus and method for direct or indirect application of a liquid or pasty medium onto a traveling material web

An application apparatus is for applying a liquid or pasty medium to a moving base. The moving base is a surface of a material web in a case of direct application and a surface of a transfer element for transferring the medium to the material web in a case of indirect application, the material web being one of paper and cardboard. The application apparatus has an inlet side and an outlet side with respect to a direction of movement of the moving base. The application apparatus includes a carrying beam; an essentially rigid supporting unit provided on the carrying beam; a sealing doctor device positioned at the inlet side of the application apparatus, the sealing doctor device being fixedly attached to the supporting unit; and a metering doctor device positioned at the outlet side of the application apparatus, the metering doctor device being fixedly attached to the supporting unit. The sealing doctor device and the metering doctor device define an application chamber therebetween.

The invention relates to a method for directly or indirectly applying a liquid or pasty application medium ( ) onto one or both sides of a continuous surface ( ), wherein the application medium ( ) is applied to the surface ( ) in a plurality of single application regions by means of a plurality of single application nozzles ( ) 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 ( ) and clearly distanced (D) from the surface ( ), the application medium ( ) 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 ( ) to be coated. The invention also relates to an apparatus for performing this method.

Method and apparatus for directly or indirectly applying a liquid or pasty application medium to one or both sides of a continuous surface

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.
