A device for applying an at least two-component viscous material to workpieces, includes a metering unit which has a number of metering valves corresponding to the number of components of the viscous material, and a static mixer which has a mixing tube, for mixing the components introduced using the metering unit into a material inlet at its first end and during passage from the material inlet to a material outlet at its second end, and an outer tube, wherein the mixing tube is received in the outer tube and, at the material inlet and at the material outlet, is sealed off from the environment using respective seals. The seals each have a circumferential cutting edge, and the cutting edges, when subjected to force in a direction towards each other, each cut into an end face on the mixing tube.

Device and method for applying an at least two-component viscous material to workpieces

The invention relates to a device () for applying a viscous material to a workpiece, in particular for applying an adhesive or sealing material to a motor vehicle body component, comprising: an application nozzle () with a material outlet opening (); and a nozzle support () that supports the application nozzle (), on which nozzle support the application nozzle () is releasably attached, wherein an application channel () extends through the nozzle support () and the application nozzle () up to the material outlet opening (). According to the invention, the nozzle support () and the application nozzle () each have a connection part (), wherein a first connection part () is inserted into a second connection part () and is encircled thereby, and the connection parts () can be moved relative to each other in a limited extent from a starting position against the restoring force of an elastic restoring element ().
