摘要

The invention relates to a wind disperser for chipboard production. A problem with wind dispersers is the evenness of the dispersion in the transverse direction. Sites becoming rather bare of substance in the course of the dispersion can be avoided by conducting more chip material to these sites so that the flow of the dispersion air to these sites is disrupted. According to the invention, this is achieved by introducing narrow, obstructive flaps 7 in the dispersion device between the flow equalizer and the dispersion site, in the way of the air flow. The motions of the flaps are individually controlled. IMAGE
