Abstract: The invention relates to a method and an apparatus for applying a pasty, preferably at least partially elastic substance used for sealing connection of a first component to a second component. In the method, the pasty substance is pressed out of an outlet opening of an application nozzle and is applied in a positionally defined manner to a connecting face of the first component. The application nozzle and/or the first component is moved in a controlled manner by an industrial robot. A delivery pump removes the pasty substance from a reservoir. The substance is conveyed to the application nozzle via a feed line, a metering pump and a following switching device, with an application nozzle being arranged behind the switching device. The metering pump controls the pressure in the pasty substance in accordance with the actual pressure is measured in the region of the switching device.
