Abstract

A perforated plate for an application device for application of a fluid to a component, preferably a motor vehicle body and/or an attachment for this, comprises at least four through-holes for passage of the fluid. The through-holes are assigned to a nozzle row with a central region and two edge regions and are spaced apart from each other by hole spacings. The at least one outermost hole spacing of the nozzle row in at least one edge region is larger than at least one hole spacing in the central region. An application device and an application method with such a perforated plate is also disclosed.
