<p>The invention describes a machine for filling the edge joint of insulating glass panes with a semi-liquid to paste-like sealing compound, consisting of a main constituent and a secondary constituent, which are different in chemical terms and in terms of their viscosity, having two pumps (3, 6) which convey the two constituents from two reservoirs (1, 2) into separate intermediate storage chambers (5, 8), and having separate, synchronously driven volumetric feed metering pumps (14, 19) for conveying the constituents in a predetermined composition to a mixer (16) and then on to a nozzle (17), the nozzle and the mixer belonging to one sub-assembly which is movably mounted as a whole on a frame of the machine. According to the invention, there is provided a gear pump (14), driven by a servomotor, as metering pump for the main constituent in combination with a piston pump (19), which serves as a metering pump for the secondary constituent and whose piston (10) is driven by a second servomotor (23), both of which preferably are part of the movable sub-assembly.</p> |
