Abstract:
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 metering pumps (14, 19), which are metering volumetrically, for conveying the constituents in a predetermined mass ratio to a mixer (16) and then on to a nozzle (17), the nozzle and the mixer belonging to a sub-assembly which is movably mounted, in its entirety, on a frame of the machine,characterized by 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 having a lower viscosity and whose piston (20) is driven by a second servomotor (23), both of which are part of the movable sub-assembly.
