Abstract: An apparatus for impregnating fiber structures with a matrix material includes a lower part having a bath for receiving the matrix material and a draining unit. The draining unit includes a wiper having a wiping edge, over which the impregnated fiber structure is guided during operation, and a surface inclined in the direction of the bath, by which matrix material draining from the fiber structure can return into the bath. The draining unit includes a cover on which a deflection unit, by which the fiber structure is pressed into the bath when the cover is mounted, is mounted. When the cover is mounted, a gap is formed between the cover and the lower part on the sides by which the fiber structure is guided into the apparatus and emerges from the apparatus. A method for impregnating fiber structures with a matrix material is also disclosed.
