Abstract
A method for producing a fibrous preform includes placing a fibrous mat onto a depositing surface, the depositing surface being formed by a web face of a mold core, a first support surface of a first support installation and a second support surface of a second support installation. The fibrous mat is covered by a film and is pressed in a planar manner onto the depositing surface by generating a vacuum. Bringing to bear the fibrous mat on lateral faces of the mold core that extend transversely to the web face is subsequently performed by moving the support installations and the mold core relative to one another in such a manner that a level differential between the web face of the mold core and the support surfaces of the support installations is enlarged. A device for producing a fibrous preform is furthermore described.
