摘要： The invention relates to a method for metering a foamed or foamable plastic (5) in a preferably discontinuous manner. At least one first component (2) for forming the plastic (5) is conveyed into a mixing chamber (11) of a mixing device (10) in which a stirring mechanism (30) that can be rotated about a rotational axis (31) is arranged. The first component (2) is loaded with a gas (4) in order to influence the formation of foam, and the plastic (4) is metered out of the mixing chamber (11) through an outlet nozzle (18). According to the invention, the pressure in the mixing chamber (11) ranges from 0.2 bar to 15 bar, the gas (4) is injected into the first component (2), preferably directly into the mixing chamber (11), by a valve device (50), and the stirring mechanism (30) disperses the gas (5) in the first component (2).
