1. A spreading unit having a shaper for spreading viscous material on a component, wherein the shaper has a first shaping contour for shaping the viscous material in the process of the spreading,
wherein at least a second shaping contour of the shaper for shaping the viscous material is configured to be brought by an actuator, in a direction of spreading, into superimposition with the first shaping contour, so that a shape of the shaper is adjustable during an application process,
wherein the spreading of the viscous material is realized by a movement of the spreading unit in a direction of application or spreading,
wherein the spreading unit comprises a nozzle for the application of the viscous material on the component and wherein the nozzle is arranged at a predefined fixed distance from the shaper,
wherein the first and second shaping contours are arranged directly one behind the other in the direction of application or spreading; and
wherein the nozzle applies the viscous material on the component such that the nozzle is maintained at the predefined fixed distance from the shaper;
wherein the first shaping contour and the second shaping contour are arranged directly one behind the other in the direction of application or spreading such that the first shaping contour lies behind the second shaping contour in the direction of spreading and is arranged at the predefined fixed distance relative to the nozzle such that the viscous material is configured to precompact or partially harden in a predefined manner on the path from the nozzle to the shaper;
wherein the second shaping contour has a course which substantially corresponds to a cross-section of the component in the region of the spreading;
wherein the second shaping contour comprises at least two contour segments which are separately movable relative to one another, wherein the at least two contour segments are arranged side by side,
wherein one of the contour segments is directly connected to the actuator, wherein the other of the contour segments is guided in a separately movable manner,
wherein the second contour segment is movable in a resiliently elastic manner in relation to the other of the contour segments; and
wherein the viscous material is applied to a joint weld of the component, wherein the joint weld is configured as a stepped weld or a fillet weld.
