PROCESS AND APPARATUS FOR FORMING AN AIR LAID WEB |
摘要 |
<p>Process and apparatus are disclosed which are suitable for high speed production of uniform, lightweight webs by air-laydown of textile fibers. A toothed disperser roll doffs the fibers into an air stream of high uniform velocity and low turbulence to form a thin fiber stream from which the fibers are deposited in web form on a moving screen. A curved disperser plate, shrouds the disperser roll and prevents premature doffing. By using a disperser plate with a rough surface, preferably one having lateral grooves, web uniformity is remarkably improved.</p> |
