An improvement in distributors for air-laid fibers wherein one or more impellers within a distributor housing receive fibers from a hammer mill or other source, and impel fibers smaller than a certain size through a first screen extending over the outlet opening of the distributor housing onto a moving forming wire. A partial vacuum is formed beneath the forming wire to hold the fibers thereon and to form a continuous web of fibrous material. The impellers are blades which rotate about a vertical shaft immediately above the first screen. The invention is directed to improvements in the first screen, wherein it is endless and is mounted for movement across the outlet opening of the distributor housing, in the same direction and at the same speed as the forming wire.

Fiber distributor

A process for coloring nonwoven webs of fibrous material, particularly air-layed webs, in which solid, water insoluble particulate pigments are introduced and intermixed with the fibers of the web to provide the coloring thereof. An initial formed web of fibrous material has a suspension of insoluble pigment in a liquid applied thereto, is fiberized, and is reformed into a web and bonded with a binding liquid. Alternatively, the pigment may be mixed with the separated fibers after the fibrous material is fiberized and before reforming.

Process for producing colored nonwoven fibrous webs

Multiple distributor heads of the Kroyer type in side-by-side position over a common suction tunnel for laying fibrous material onto a foraminous forming-wire screen travelling along the tunnel.
