Abstract
A system and apparatus for forming webs from textile fibers entrained in an air stream in a conduit with a perforated plate dividing the interior of a housing into first and second chambers so that the entrained fibers fall to the bottom of the first chamber and the air passes through the plate while a portion of the plate is oscillated. The passage between the conduit and first chamber increases in cross-section from conduit to first chamber to reduce the velocity of the air and entrained particles.
