A method and a device for the continuous forming of a mat of fiber or particle materials, where the material is deposited on a forming web, and where the cross profile of the mat is adjusted substantially in the entire length of the former by raising or lowering the web locally in cross direction in one or several positions. The adjustment is achieved in that longitudinal profiles beneath the forming web can be raised or lowered independently of each other, so that the bottom of the forming installation can assume different forms for compensating for unevenesses in the cross profile. The raising and, respectively, the lowering can be obtained in that wedges on the lower side of the profiles are arranged to slide against wedges placed in recesses on cross supporting beams located beneath. |
