Abstract
Disclosed is an apparatus and method for the distribution of composite mixtures into an initially open mold, such as the components utilized in the manufacture of frictional components containing asbestos. The apparatus includes a hopper or reservoir for holding and dispensing the mixture onto a collection surface and, suitable means for moving the collection surface relative to the hopper. A deflector is mounted below the hopper, while supply and feed rotors, separated by a reciprocator means are carried within the hopper. Means are further provided for driving the deflector, rotors and reciprocator. The apparatus may further include means for sweeping and levelling the composite mixture in the mold. The preferred method of operation includes the steps of cavitating the mixture within the reservoir, comminuting agglomerations of the mixture therein, feeding the mixture through apertures in the reservoir, further comminuting agglomerations outside of the reservoir and, moving the collection surface relative to the hopper.
