Abstract: The present invention relates to a method for spinning fibers, or fiberizers, using a rotary fiber-making die system made up of thin plates, embodied by a housing fixture, configured and stacked to define slots, channels and/or grooves through which the material used to make the fibers will flow. The die system allows for the production of different size and types of fibers, including nanofibers having a diameter of less than 1 micron, and facilitates a variety of cost effective methods for extrusion. The use of plates means the dies can be manufactured cost effectively, with easier clean-outs, replacements and/or variations.

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.
