<p>The invention relates to a metering and mixing device (1) for multi-component substances, in particular multi-component adhesives, comprising at least two associated cartridge accommodating devices (2, 3) for accommodating replaceable cartridges (2.1, 3.1) having individual substance components, a discharging device (4, 5, 8, 9, 11, 16) for simultaneously discharging the substance components from the cartridges (2.1, 3.1) through component outlets by means of discharging pistons that plunge into the cartridge accommodating device (2, 3) or cartridges, and a mixing device (7), which is connected to the component outlets, mixes the discharged substance components, and outputs said substance components in the mixed state. The invention is characterized in that at least one discharging piston (11) has a thread (11.1) in such a way that the discharging piston (11) can be driven forward by means of the thread when the discharging piston (11) is rotated relative to the cartridge accommodating device (2, 3).</p> |
