Problems solved by technology

[0010] However, the cycle time required to open the motor vehicle door in order to apply the sealant on the respective flange seam is a waste for the actual application of the sealant
In some cases, this can result in multiple operating cycles being required to apply the sealant to the various flange seams of the motor vehicle body
[0011] Furthermore, the opening of the motor vehicle door for the application of the sealant to the flange seam requires an additional manipulating robot, with associated increased investment costs and a larger required space for the spraying station

Embodiment Construction

[0043] figure 1 The area of ​​the gap 1 between the motor vehicle door 2 and the screen wing 3 (baffle) is shown. In the closed state shown in the figure, the motor vehicle door 2 and the screen wing 3 overlap to enhance the impact safety.

[0044] The motor vehicle door 2 has an inner panel 4 and a sheet metal panel 5 forming a flange around the curved edge of the inner panel 4 . In the region of the curved edges, the inner panel 4 is connected to the sheet metal panel 5 by means of an adhesive layer 6 . In this construction, the danger is that in the area of ​​the flange seam, moisture will enter the gap between the bent edge of the inner panel 4 and the flanged edge of the sheet metal panel 5 and cause corrosion. The flange joint between the inner panel 4 and the sheet metal panel 5 is therefore sealed with a sealant 7 which is at right angles to the plane of the drawing along the entire length of the flange joint to prevent the penetration of moisture into the flange join...

Abstract

The invention relates to an applicator (8) for applying a coating means to a component (2), in particular for applying a sealing compound (7) to an edge-raised seam on a rear side of a motor vehicle body component, in particular through a gap (1) between two overlapping motor vehicle body components, with a nozzle (11) for dispensing the coating means onto the rear side of the component (2) and with an elongated curved nozzle carrier (10) in order to position the nozzle (11) on the rear side of the component (2) to be coated, starting from the front side of the component (2) to be coated. It is proposed that the nozzle carrier (10) be repeatedly curved such that the applicator can be guided through the gap.

Description

technical field [0001] The present invention relates to an applicator for applying a coating compound to components, in particular for applying a sealant to flange seams on the rear side of motor vehicle body components, said applicator in particular Can project through a gap between two overlapping motor vehicle body assemblies. Background technique [0002] Motor vehicle body components, such as doors or hoods, often have so-called flange seams, where it is possible to bond two sheet parts to each other where a flange is formed around the edge of another sheet part bonded. Here, there is a risk that moisture will penetrate into the gap between the two sheet parts and cause it to corrode. It is therefore known to apply a sealant to a flange seam between two sheet-like parts in order to seal said flange seam, with the result that the penetration of moisture and the associated corrosion are reliably prevented. [0003] When coating motor vehicle body doors, it is practice ...
