A process and mechanism for the dry screen forming of fibers to attain a dispersion in air of substantially individual fibers from which a fibrous sheet is formed. Fibrous nits, pills and flocs are removed from the dispersion by rolling the nits, pills and the like into elongated shapes as they pass a fiber screening member and carrying the elongated fibrous bodies from the dispersion of fibers and away from the sheet forming area for the fibers. The mechanism includes a fiber screening member, a fiber receiving member on which the sheet is formed and a foraminous member which rolls the nits, pills and the like between it and the fiber screening member as the air dispersion of fibers passes toward the fiber receiving member. |
