System for removing foreign fibers from air stream containing useful fibers uses optical detector to control selective blowing feeding unwanted fibers into funnel connected to horizontal pipe, through which air flows which removes them

摘要

The system for removing foreign fibers (8) from an air stream containing useful fibers uses an optical detector (2) to control selective blowing (4). This feeds the unwanted fibers into a funnel (5) which opens at its narrow end into a horizontal pipe (6),through which air flows which removes them.
