Abstract
An air stream is caused to impinge on a collecting surface disposed in a sharply defined suction zone. Fibers having a predetermined maximum length are entrained by said air stream to cause said fibers to be delivered to and form a condensed sliver on said collecting surface. Air is sucked in said suction zone at a rate which is approximately as large as the rate of said air stream. Said condensed sliver is drawn from said collecting surface and is subsequently twisted to form a thread. Said thread is drawn off while being held against rotation. The suction zone has in the direction in which said condensed sliver is drawn off a dimension which is approximately as large as the maximum length of said fibers. The suction zone has at right angles to said direction a dimension which is approximately as large as the diameter of said condensed sliver.
