Abstract (en)

[origin: EP1908563A2] A method for checking and removing non-uniformities during fabrication process in which a descending and/or sliding flow of material is checked for non-uniformities after pre-treatment from leakage or dispersion. The flow of material is initially spread by a fanning device, and then examined for non-uniformities by through-radiation and the ascertained non-uniformities are removed by a short-term extraction of a partial fraction over the width of the material flow, which is then re-processed. Independent claims are given for the following. (1) (A) A device for detecting and removing non-uniformities from a stream of material (2) (B) An installation for detecting and eliminating non-uniformities from moving flow of material during fabrication material boards and panels.
