1. Application device for the application of an application medium onto a component, comprising:
at least one print head for application of the application medium and for mounting on an application robot, the print head movable in a direction of movement,
at least three nozzle rows which can be moved by the application robot, wherein the at least three nozzle rows comprise a first nozzle row with several nozzles spaced along a longitudinal direction and for the output of application medium jets, a second nozzle row with several nozzles spaced along the longitudinal direction and for the output of application medium jets, and a third nozzle row with several nozzles spaced along the longitudinal direction and for the output of application medium jets, and
a first nozzle plate having the first nozzle row and no additional nozzle rows, a second nozzle plate having the second nozzle row and no additional nozzle rows, and a third nozzle plate having the third nozzle row and no additional nozzle rows, characterised in that
the nozzles of the second nozzle row are offset from the nozzles of the first nozzle row along the longitudinal direction, and the nozzles of the third nozzle row are offset from the nozzles of the second nozzle row along the longitudinal direction and are offset from the nozzles of the first nozzle row along the longitudinal direction,
the first nozzle plate, the second nozzle plate, and the third nozzle plate are of identical design and are offset with respect to each other in the longitudinal direction such that individual uneven offsets are present for each nozzle plate and to provide the offset of the nozzles of the second nozzle row and the third nozzle row,
the first nozzle row, the second nozzle row, and the third nozzle row are rotatable from a first position with the longitudinal direction extending perpendicular to the direction of movement of the print head to a second position with the longitudinal direction extending oblique to the direction of movement of the at least one print head, and
a first motor serves to rotate the first nozzle row.
