Abstract: The disclosure relates to a coating method for coating a component (e.g. motor vehicle body component) with a coating agent (e.g. paint), that includes steps of Defining a pattern on the component surface of the component to be coated, the pattern being a surface area outlined by a contour, and areal coating of the component surface with the coating agent within the contour, sharp-edged coating of the component surface with a coating agent along at least a portion of the contour of the pattern.

Abstract: The disclosure relates to an operating method for a coating system (e.g. painting installation) for coating components (e.g. motor vehicle body components).

Abstract: The disclosure concerns an applicator, in particular a printhead, for applying a coating agent, in particular a paint, to a component, in particular to a motor vehicle body component or an attachment for a motor vehicle body component, having a plurality of nozzles for applying the coating agent in the form of a coating agent jet, and a plurality of coating agent valves for controlling the release of the coating agent through the individual nozzles, and having a plurality of electrically controllable actuators for controlling the coating agent valves. The disclosure provides that a control circuit for electrically controlling the actuators is integrated in the applicator.

Abstract: The disclosure concerns an applicator (e.g. print head) for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component), having a nozzle chamber with a plurality of nozzles for dispensing the coating agent in the form of continuous jets or droplets, the coating agent flowing during operation through the nozzle chamber to the nozzles so that the nozzle chamber is filled with the coating agent during operation. The print head further comprises a plurality of slidable valve needles associated with the individual nozzles and selectively opening or closing the respective nozzle depending on the position of the valve needles. Furthermore, the print head according to the disclosure contains an actuator chamber for receiving actuators for displacing the valve needles.

Abstract: The disclosure concerns an applicator (e.g. printhead) for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component), having at least one nozzle row with a plurality of nozzles for dispensing the coating agent in the form of a jet in each case, the nozzles being arranged along the nozzle row and in a common nozzle plane, and having a plurality of actuators for controlled release or closure of the nozzles. The disclosure provides that the individual actuators each have an outer dimension along the nozzle row which is greater than a nozzle distance along the nozzle row.

Abstract: The disclosure relates to a cleaning device for cleaning a nozzle applicator, which is designed for applying a coating agent to a component and has a plurality of application nozzles in a nozzle region in order to discharge the coating agent through the application nozzles during application in an application direction. The cleaning device comprises a rinsing agent supply for supplying a rinsing agent for cleaning the nozzle applicator, and a docking interface for docking the nozzle applicator to be cleaned to the cleaning device. The disclosure provides that the docking interface is configured to flush the rinsing agent into the nozzle applicator through the application nozzles of the nozzle applicator in a direction opposite to the normal application direction. Furthermore, the disclosure comprises a corresponding cleaning method.

Abstract: The disclosure relates to an applicator, in particular a printhead, for applying a coating agent, in particular a paint, to a component, in particular a motor vehicle body component or an add-on part for a motor vehicle body component, having at least one nozzle row with a plurality of nozzles for dispensing the coating agent in the form of a coating agent jet, the nozzles are arranged one behind the other in a nozzle plane along the nozzle row at a specific nozzle spacing, and having a plurality of actuators for controlling the release of coating agent through the individual nozzles, the actuators each having an outer dimension along the nozzle row. The disclosure provides that the nozzle distance between the adjacent nozzles of the nozzle row is smaller than the outer dimension of the individual actuators along the nozzle row.
