Air flow control apparatus for a fiber air-lay machine |
摘要 |
An apparatus is disclosed for high speed production of uniform webs by air-laydown of textile fibers. A feed batt of staple fibers is fed to a toothed disperser roll that projects the fibers at high velocity and low angle into an airstream of high uniform velocity and low turbulence to form a thin fiber stream from which the fibers are subsequently separated on a moving screen in the form of a web. Air flow control means upstream of the toothed dispenser roll deflects the air stream at a constantly varying angle of deflection to improve fiber laydown uniformity.
