Abstract
The apparatus for mixing multicomponent plastics, in particular polyurethane, has a steadying attachment 1 which is arranged at the outlet orifice 12 of a mixing head 10. The steadying attachment is equipped with a plurality of lamellae 3 which are movable in the region of the emerging mixture of components and run in the direction of flow of the said mixture. Advantageously, the lamellae can be moved forward and back in a guide housing which has webs 2 which occupy the space between the lamellae and thus ensure cleaning. Steadying is achieved by greater friction with the wall and an increase in the outflow cross-section.
