Abstract:
1. A method for preparing a paste-like compound comprised of at least a first constituent and a second constituent, the paste-like compound setting after the constituents that are initially present in separate storage containers have been mixed, and for injecting the setting, paste-like compound into an edge joint of an intermediate space between two glass panels of an insulating glass pane, by delivering the at least two constituents from the storage containers into separate intermediate storage units, from which the at least two constituents are delivered into a mixer, in which the at least two constituents are mixed with one another while passing through the mixer and the setting, paste-like compound leaving the mixer is injected into the edge joint of the intermediate space between the two glass panels by a nozzle comprising at least one opening, wherein the nozzle is directed into the intermediate space between the glass panels, while the nozzle is moved along the edge of at least one of the two glass panels, by means of a device for injecting a setting, paste-like compound into the intermediate space between the two glass panels, the device comprising: a first pump for pumping the first constituent from a first container; a first intermediate storage unit for the first constituent; a first pressurizer for pressurizing the first intermediate storage unit to a first input pressure; a first pump-storage unit duct from the first pump to the first intermediate storage unit; a first motor driven gear pump for pumping the first constituent; a first storage unit-gear pump duct; a dynamic mixer, the dynamic mixer having a delivery direction on a longitudinal axis, a rotatable mixing shaft extending along the longitudinal axis and mixing elements extending from the mixer shaft and differing from 90° from the longitudinal direction to effect an advance in the delivering direction of an input of paste-like compounds in response to the rotation of the mixing shaft to reduce the loss of pressure which would occur where the mixing elements do not differ from 90° ; a first gear pump-dynamic mixer duct extending between the first gear pump and the dynamic mixer; a second pump for pumping the second constituent from a second container; a second intermediate storage unit for the second constituent; a second pump-storage unit duct from the second pump to the second intermediate storage unit; a second pressurizer for pressurizing the second intermediate storage unit to a second input pressure; a second motor driven gear pump for pumping the second constituent; a second storage unit-gear pump duct; and a second gear pump-dynamic mixer duct extending between the second gear pump and the dynamic mixer; wherein the dynamic mixer delivers mixed first constituent and second constituent, and wherein the device further includes a nozzle for receiving from the dynamic mixer and delivering to the joint edge of the intermediate space between the two glass panels the mixed first constituent and second constituent; said method comprising the following steps:
