Abstract
A method of cleaning fiber of dust and particulate matter thereon includes the steps of directing the fiber passage having an entrance end and an exit end; protecting the fiber from abrasion at the entrance end and the exit end; passing the fiber through a vacuum chamber in the fiber passage; directing a fluid spray against the fiber in a direction opposite to the direction of movement of the fiber along the passage at a velocity sufficient to dislodge particulate matter from the fiber; and exhausting the fluid and the particulate matter from the vacuum chamber.
