Abstract
The invention is particularly related to the problems of dispersing fiber to obtain a uniform distribution. The invention includes tapered ducts oriented at an appropriate angle relative to the horizontal for redirecting and decreasing the speed of an air stream containing fiber therein such that the fiber precipitates from the air stream and falls gently to form a uniform fiber bed in a bin.
