Abstract

A method for coating a metallic support profile with a layer of a corrosion-resistant material, includes providing the metallic support profile with a surface to be coated, providing a layer element of the corrosion-resistant material adapted to the surface to be coated, applying an adhesive, curable substance to at least one of the surface to be coated and the layer element, applying the layer element to the surface to be coated, covering the arrangement of support profile and layer element by a compacting element, pressing the layer element onto the surface to be coated by the compacting element to achieve a predetermined joint thickness occupied by the adhesive substance, curing the adhesive substance while maintaining the joint thickness to generate a bond, and removing the compacting element.

First claim

The invention claimed is:

1. A system for coating a metallic support profile with a layer of a corrosion-resistant material, comprising:
a receptacle for holding the metallic support profile with a surface to be coated, wherein the metallic support profile is a rail configured for installation in a cabin of a commercial aircraft and includes undercuts arranged therein,
a layer element of the corrosion-resistant material, the layer element adapted to the surface to be coated,
an adhesive substance for adhering the layer element to the surface to be coated,
a compacting element dimensioned to cover the surface to be coated and the layer element disposed thereon, wherein the compacting element is configured to maintain a predetermined joint thickness occupied by the adhesive substance while curing, and
a drive device which is couplable with the compacting element and is configured to press the compacting element onto the layer element with a predetermined force and for a predetermined time,
wherein the compacting element is elastically deformable so that the compacting element adapts to the shape of an arrangement of the metal support profile and the layer element during pressing,
wherein the receptacle is trough-shaped and has a holder for holding the support profile in a fixed position, and
wherein the holder comprises a plurality of profile pieces in flush contact with the metallic support profile and the undercuts, and with the receptacle such that the metallic support profile cannot slip in the receptacle.

2. The system according to claim 1 ,
wherein the compacting element comprises a gas impermeable membrane spanning the receptacle to create a gas-tight space between the receptacle and the membrane, and
wherein the drive device comprises a fluid pump which applies a negative pressure to the space so that the membrane is forced onto the layer element and the support profile.

3. The system according to claim 2 ,
wherein the receptacle comprises a cover placeable on a side of the gas impermeable membrane facing away from the support profile, and
wherein the drive device is configured to generate an overpressure in a space present between the gas impermeable membrane and the cover.

4. The system according to claim 1 ,
further comprising a gas-permeable, at least flexurally soft surface element for laying on the arrangement of support profile and layer element.

5. The system according to claim 2 ,
further comprising a foil for overlaying the arrangement of the support profile and layer element to enhance sliding properties of the membrane.

6. The system according to claim 1 ,
further comprising at least one pressure stamp for application to the arrangement of support profile and layer element,
wherein a lower side of the at least one pressure stamp facing the arrangement has a smaller area than an area on an upper side of the at least one pressure stamp facing the compacting element.
