ABSTRACT:
A non-woven fibrous web is continuously air-laid by directing a fluid stream of fibers from a rotating spinner against the inner surface of a moving foraminous belt which travels in an arc substantially around the circumference of the spinner, with suction being applied to the outer surface of the foraminous belt to facilitate uniform fiber lay-down and to remove the fluid.
