Abstract

An apparatus is disclosed, which controls and meters the feed of fibers into a fluid which includes a housing having an intake opening and a discharge opening, two or more toothed metering elements mounted on a plurality of spindles, and a shear bar disposed within the housing above and between the toothed metering elements. The spindles are rotatably mounted within the housing. A fluid is disposed adjacent the discharge opening for receiving fibers. In some cases, a mass of fibers is introduced into the apparatus via the intake opening, the mass of fibers contacts the shear bar and the toothed metering elements, and may be divided into substantially discrete fibers by the contact with the shear bar and the toothed metering elements, and delivery of the fibers to the fluid is metered by controlling rotational speed of the toothed metering elements.
