Abstract
A staple fiber batt of improved uniformity is made by the fibers falling onto a moving conveyor, skimming off the top of the batt by jets of air flowing across the top of the batt, which thereby determines the level of the batt, and redepositing the skimmed off fibers onto said batt. The batt can then be compacted for further processing.
