A drive apparatus of a metering and mixing device is provided for multi-component materials, for example, for multi-component adhesives. The metering and mixing device can have at least two cartridge-accommodating devices for accommodating replaceable cartridges having individual material components, and a discharging device for simultaneously discharging the material components from the cartridges through the component outlets by discharging plungers that plunge into the cartridge-accommodating device and a mixing device. A transmission unit connects a drive machine, and has a coupling for forced connection of a discharge of at least two material components by correspondingly synchronized actuation of discharging plungers by respective discharging rods.
