A device for applying a viscous material to workpieces, has a nozzle holder and an applicator nozzle which is arranged on the nozzle holder and has a material line extending from a material inlet, for introduction of the viscous material, to a nozzle opening for emergence of the viscous material. The material line has an inlet portion, extending in a first direction from the material inlet, and an outlet portion, extending to the nozzle opening in a second direction transverse to the first direction, and the applicator nozzle is mounted on the nozzle holder pivotably about a pivot axis forming a longitudinal center axis of the inlet portion.

An automated mobile sprayer (AMS) includes a mobile base, an applicator arm supported by the mobile base, and a nozzle extending from the applicator arm. The nozzle receives fluid from a fluid supply and generates an atomized fluid spray for application to a surface. The applicator arm moves vertically relative to the mobile base and the surface to cause the nozzle to generate a vertical fluid stripe. The mobile base moves laterally relative to the surface to cause the nozzle to generate a horizontal fluid stripe.
