<p>Apparatus for processing textile fibers is disclosed which includes a carding machine (16) and a batt former (A). Batt former (A) includes an air circulation loop which includes a plenum (B), air compacting chamber (C), air separating means (72, 74), acceleration channel (30), duct (46), and fan blower (54). Fan blower (54) has an adjustable angle of incidence "a" to direct a jet of fiber-laden air into plenum (B) against a splash plate (66) to cause fibers to be deposited in fiber compacting chamber (C) in a cross-directional profile so that fibers at side walls of the plenum may have increased residence time to the fiber compaction chamber compensating for side wall friction. A first separated air flow (5) is divided by side channels (92a, 92b) and combined with a second air flow (4) to form supercharged air flow regions at the sides of the air flow passing through acceleration channel (30). This accelerated air flow with supercharged side regions creates an air knife in combination with plate (26) which passes through teeth (28a) of opening roll (28) to doff fibers from the opening roll. In this manner, efficient doffing across a working width of opening roll (28) is achieved with minimum energy from fan (54).</p> |
