Abstract
A melt overflow apparatus for controlling various elements in response to incremental changes in parameters which affect the linear density of a continuous metal fiber mat or metal strip being produced is described. The net width of fibers being cast against a rotating, cylindrical casting wheel is measured by an infrared detector. A similar infrared detector is used to measure the net width of a metal strip being formed against a casting wheel. The weight of a portion of the strip or fiber mat is also measured. The weight and net width values are relayed to a control system which then controls various elements used in producing the metal product. These devices include electric motors driving both the casting wheel and a conveyer means for transporting the fiber mat or strip. A ceramic plunging body driven into a pool of molten metal to overflow onto the casting wheel can also be controlled.
