Abstract: Applicator device for flowable reaction masses includes a crossbeam for distributing reaction mass and lines for feeding the reaction mass to the crossbeam, the crossbeam being formed with an inner hollow chamber communicating with the feeding lines for receiving reaction mass therefrom and an outer hollow space external to the inner hollow chamber, an inner wall separating the outer hollow space and the inner hollow chamber from one another, the inner wall being formed at uppermost locations thereof with overflow openings for passage into the outer hollow space of reaction mass fed by the feeding lines into the inner hollow chamber, and an outer wall at least partly surrounding the outer hollow space and formed with discharge openings for discharge of reaction mass received in the outer hollow space from the inner hollow chamber.
