Abstract
An application nozzle for applying a viscous material to workpieces includes a nozzle body and an application duct for the viscous material, the duct extending inside the nozzle body from a material inlet opening to a material outlet opening. At least one filler element is located in the application duct, which filler element constricts the cross-section of the application duct and extends from a first end remote from the material inlet opening to a second end at the material outlet opening.
Claims18
An application nozzle for application of a viscous material in the form of a material bead to workpieces, the application nozzle having a nozzle body and having an application channel for the viscous material, wherein the application channel extends in the nozzle body from a material inlet opening to a material outlet opening, wherein at least one filler body is arranged in the application channel and narrows the cross-section of the application channel, wherein the at least one filler body borders on the nozzle body directly over an entire length of the at least one filler body, the at least one filler body extending from a first end of the at least one filler body arranged at a distance from the material inlet opening to a second end of the at least one filler body;
- said second end is arranged at the material outlet opening in the application channel so that the viscous material flows around an outside of at least one filter body to form a cavity in the material bead of the viscous material when the material bead exits from the material outlet opening;
- and wherein the at least one filler body has a cross-section that increases in size from the first end of the at least one filler body to the second end of the at least one filler body.
