Abstract: A process and an apparatus for substantially uniformly distributing glass fibers onto a forming bed. The apparatus is mounted above the bed for movement relative thereto along the length of the bed and is receptive of glass fibers for chopping same into desired lengths. A hood structure is downstream of the chopping and comprises three chambers. A first chamber defining a receiving zone in the process receives the chopped glass fibers which are dropped into the hood and a second chamber defining a dispersing zone is in communication with the first chamber and downstream thereof and disperses the glass fibers received from the first chamber to effect a random uniform matrix thereof along the width of the bed. The dispersion is carried out by a turbulence that is created within the chamber. The third chamber defining a distributing zone is disposed downstream of the second chamber and has an adjustable length elongated outlet aperture which extends across a desired width of the bed.
