Vorrichtung zum Zufuehren von kurzen Fasern

DE 102007047548 A1 UPAB: 20090428 NOVELTY - The device has a container (5) with a dosing opening (8) and an outlet opening (10), where the container is tapered at the outlet opening through two inclined container walls (7). A conveying screw (11) is arranged between the container walls for conveying fibers fed into the container. The container walls are designed as endlessly rotating belt conveyors, which support the movement of fibers to the outlet opening. A surface of a conveyor belt (12) is roughened and provided with driving elements such as cross-beams. USE - Device for supplying a short fiber i.e. staple fiber, into a compound extruder or a machine for subsequent processing of the fiber. Can also be used for natural fiber and synthetic fiber. ADVANTAGE - The container walls are designed as endlessly rotating belt conveyors, which support the movement of the fibers to the outlet opening, so that the fibers with small bulk density and weight are conveyed continuously and evenly into the extruder
