A method and device for preparing a paste-like compound having at least two constituents which set after having been mixed. The mixed compound is injected into an intermediate space between two glass panels of an insulating glass pane by delivering the at least two constituents from storage containers into separate intermediate storage units from which they are delivered into a mixer in which the constituents are mixed while passing through the mixer. The compound leaving the mixer is injected into the intermediate space between the two glass panels by a nozzle which has at least one opening directed into the intermediate space between the glass panels. The nozzle is moved along the edge of at least one of the two glass panels. The constituents of the paste-like compound are pumped using gear pumps from the intermediate storage units into the mixer, where they are dynamically mixed by motor-driven mixing elements.
