Abstract
The present invention relates to a method and a device for impregnating fibrous material such as, for example, fiber bundles, fiber strands, woven textiles or fiber mats, in which an impregnating agent is introduced into the spaces in the fibrous material, and the individual fibers are surrounded and/or soaked through, wherein the supply of impregnating agent takes place via apertures in a supply body over which the fibrous material is moved, wherein the device is provided with a supply body with apertures for supplying an impregnating agent, furthermore is provided with a transport means for moving the fibrous material through the device or respectively past the supply body, and means for supplying impregnating means to the supply body. In order to provide a method and a device which obtain a more complete and more uniform soaking through of the fibrous material, it is proposed according to the invention that supply takes place over a large area via a very large number of small apertures, in that a substantially homogeneous, porous or respectively permeable material is used for the supply body, and that correspondingly the supply body is composed of a substantially homogeneous, porous body which is permeable for the impregnating agent.
