Abstract
A process of feeding carded fiber to an airlay and particularly to combining carding technology with airlay technology. A carding machine portion is arranged to card fiber while a disperser-roll in the airlay portion picks the individualized carded fibers from a tool bed roll and centrifugally doffs them into an air stream. As such, airlays will be able to handle longer fiber lengths which conventional airlay equipment is unable to handle or satisfactorily open up. Further, an improved process for doffing fiber from a airlay machine and particularly centrifugally doffing fiber from a carding machine.
