Embodiment Construction

[0083] The exemplary embodiments of the invention described with reference to the figures partly correspond to one another, wherein similar or identical components bear the same reference numerals, and in order to avoid repetition, reference is also made to the description of other exemplary embodiments or to the description of the figures.

[0084] figure 1 shows a side view of a nozzle arrangement 1 according to an embodiment of the invention, figure 2 shows along the figure 1 The relevant longitudinal sectional view of the AA line, image 3 A relevant top view of the nozzle arrangement 1 is shown.

[0085] will now be combined Figures 1 to 3 The nozzle device 1 is described.

[0086] The nozzle arrangement 1 is used for dispensing a viscous application medium, eg PVC material (polyvinyl chloride), in the form of a jet S1 to components, in particular motor vehicle components (eg folds, edges or transition joints of motor vehicle components). The motor vehicle compon...

Abstract

The invention relates to a nozzle device (1, 10) for dispensing a viscous application medium in the form of at least one jet (S1, S2) onto a component (100), preferably for the encircling applicationof the application medium onto a rabbet, edge or transition joint of the component (100), wherein the at least one jet (S1, S2) defines a jet width (B1, B2). The nozzle device (1, 10) comprises an opening configuration (2) for forming at least one slit opening (3.1, 3.2) to dispense the application medium and is in particular distinguished in that the opening configuration (2) is concave to effecta narrowing of the jet width (B1, B2) towards the dispensing side (A). The invention also relates to an associated method.

Description

technical field [0001] The invention relates to a nozzle arrangement for distributing a viscous, in particular highly viscous, application medium in the form of at least one jet or at least two jets onto a component, preferably for applying the application medium to the component in a circumferential manner folds, edges or transition joints. The component is preferably a motor vehicle component (eg a vehicle body component), but it may also be eg a commercial vehicle component (eg a commercial vehicle body component, an aircraft component, a window (eg window pane) or a façade component. Background technique [0002] With regard to the general prior art, reference is first made to DE 20 48 865 B. [0003] refer to Figure 16 , according to the prior art, vertical seams such as component edges, which occur especially in the sill area or on the side rails of motor vehicles, are passed through conventional robot-guided flat-jet nozzles (also called flat-flow nozzles) made of h...
