Abstract
The invention relates to a process which enables foreign bodies to be rapidly recognized and filtered out of fibre processing lines. A stream of fibres is inspected by color sensors. If foreign bodies are detected in the flow of fibres, they are blown out by compressed air nozzles (13). The inspection and filtering out can be performed with continuous operation, and purposeful filtering out blows only a few foreign bodies out with the fibres.
