摘要： Apparatus including a cone mounted for rotation in a container having a peripheral wall and on to which wood wafers are directed. A plurality of tubes having upper ends opening into the container around the cone for receiving wafers as they are thrown off radially from the cone. The opposite ends of these tubes are arranged in a plurality of rows which extend transversely of a path along which supporting plates are moved so that the wafers are deposited on the plates to form mats and are evenly distributed across the plates.

摘要： Apparatus for fiberizing a sheet of wet-pressed pulp fibers into individual fibers and forming individual, spaced-apart pads of such fibers, as follows. A generally enclosed, stationary chamber is provided which has an open bottom end and a slot in an upper portion to receive a sheet of wet-pressed pulp fibers. A driven fiberizing device is rotatably mounted in the upper portion of the chamber for fiberizing the sheet into substantially individual fibers. A longitudinally moving conveyor belt having longitudinally-spaced groups of small perforations therein along the length thereof corresponding to the desired configuration and spacing of the fiber pads being formed in positioned for movement along the open bottom end of the chamber directly below the fiberizing device for cooperating with the chamber for forming an enclosed pad forming area in a lower portion of the chamber and for receiving the fiberized fibers on its upper surface and conveying the fiberized fibers out of the chamber. A stationary vacuum device is positioned at the lower surface of the belt and directly below the chamber for creating a vacuum through the groups of perforations in the moving belt for causing the fibers to be pulled to the groups of perforations for forming individual, spaced-apart pads on the moving belt over the groups of perforations and within the lower portion of the chamber for being conveyed by the belt out of the chamber after formation thereof.

摘要： Fibers are suspended in a rising stream of air which is deflected into a distribution chamber having a bottom formed by a belt-like, gas-permeable screen advanced over a suction box, whereby a dry fiber web is produced on said screen. At the deflection of the fiber-carrying air stream a second stream of air is added to control the inflow of suspended fibers into the distribution chamber and to cause the fibers to follow a trajectory through said chamber. The pattern of fiber deposition on the moving screen is further controlled by admitting additional air from above through an adjustable opening in the enclosure of the distribution chamber.

摘要： Apparatus for producing multilayer fibrous mats is provided which can mix and form alternate short and long fiber layers continuously in a single stage of process, both layers being held together by interfiber bonds at their interfaces under the influence of suction air. The apparatus is comprised of a disintegrator unit producing a short fiber layer and a defibrator unit operatively associated therewith for producing a long fiber layer, both units designed to deposit the respective fibers on a conveyor moving above suction boxes.
