Abstract
The apparatus for injecting one or more additives (4) into a flow (5) of a highly viscous liquid into which the additives are to be admixed comprises a supply member (3) for each additive. This supply member is releasably connected to a tube section (2) conducting the flow. Each of the supply members has a supply channel (30) for the additive which stands transversely to the direction of flow. The additives temporarily form separate phases which coexist with the phase of the highly viscous liquid after having been fed in. A wall section (1) which is oriented in the direction of flow and can be flowed about on both sides by the highly viscous liquid is associated in each case with at least some of the injection members. Its inner side (10), that lying nearer the center of the tube, spans a surface on which the exit opening (35) of the supply member at least approximately lies. The wall section is provided downstream from the discharge opening as a spreading means (11) for the additive supplied.
