ABSTRACT:
The invention relates to a method and a device (1) to prevent contamination on a wall inner side (53, 54, 55, 56, 67) of a transport device (10) for fibers (60) which are designated for the production of fiberboards and which after wetting with glue in a dry-gluing unit (2) are transported by the transport device to a further processing unit (13) by means of transport air. By returning dried material (50), which has been acquired during the course of further processing of the glued fibers and no longer has any cold-sticky glue, into the flow (7) of fibers (60), which still comprise cold-sticky glue, in the transport device, the said contamination is prevented in an effective and inexpensive manner.
