ABSTRACT:
A fiber making device, fiber making method, and apparatus which incorporates a series of two or more stacked, thin circular die plates, two end plates and two enclosure plates, where all of the plates cooperate to form a chamber having opposite ends and define a first end and a second end. The first end will receive material to be formed into fibers and the second end will receive a fiberizing fluid, although the second end could be used to supply a second fiber forming fluid to form composite fibers. All of the die plates have a central opening to receive fiber forming material, and at least one of the die plates has an outflow edge peripheral to the plate which will define a spinneret orifice, which is in fluid communication with said central opening, and which will allow the flow of material along a radial path through which fibers can be extruded. At least one of the die plates has an outflow edge peripheral to the plate which will define an opening and allow for the flow of a fiberizing fluid from the opening so that the fiber forming material flowing from the spinneret orifice will form fibers which will be engaged and shaped by the fiberizing fluid.
