Abstract
A method of continuously producing an opened fiber bundle for a cleaning member while conveying a fiber bundle, includes the steps of applying a tensile force to the fiber bundle; relaxing the tensioned fiber bundle to open the fiber bundle; and blowing air in a direction intersecting with the machine direction of the belt-shaped fiber bundle through an air outlet of an air feeder, to further open the belt-shaped fiber bundle and widen the belt-shaped fiber bundle in the width direction. An outer portion in the width direction of the air outlet is disposed downstream in the machine direction, compared with an inner portion in the width direction of the air outlet.
