Abstract
Apparatus for cleaning textile fibers such as cotton, etc. is disclosed wherein the fibers are conveyed by an air current to an opening roller cooperating with a grate, and the transport air is separated at a feed box. The separated air (17) serves for discharging contaminants accumulating in a space (9, 11) beneath the cleaning grate (8). The opening roller (7) may be provided with a toothed wire (20) whose teeth have a relatively acute top rake (22).
