Nozzle device for applying a viscous material

A nozzle device for applying a viscous material to workpieces, having a nozzle body (12) that has a central part (14) having an end face (16) and two side parts (18) that project away from the central part (14), at a distance from one another, wherein each of the side parts (18) has a transverse side (20) that follows the end face (16) and runs transverse to the end face (16), wherein the two transverse sides (20) face one another, wherein an exit opening (22) for the viscous material is arranged in each transverse side (20), and wherein a material channel (44) runs through the nozzle body (12) to each exit opening (22) and connects the exit openings (22) to a material entry opening (40) of the nozzle body (12), wherein the nozzle body (12) has a main body (26) and a cover body (30) that is releasably attached to the main body (26), wherein the material channels (44) are delimited, at least section by section, both by a delimitation surface (50) on the main body (26) and by a delimitation surface (52) on the cover body (30).
