Abstract:
1. A fiber spinning device mountable to rotate on a shaft in a fiberizer comprising: two or more stacked, thin circular die plates, two end plates and two enclosure plates; wherein at least one of the die plates is a fiber forming die plate and at least one of the die plates is fiberizing fluid die plate: wherein all of the die plates have a center opening and all of the plates cooperate to form a central open chamber which can fluidly communicate with a source of fiber forming material to receive fiber forming material; wherein the device has means for receiving material to be formed into fibers; wherein the device has means for receiving a fiberizing fluid; wherein at least one of the fiber forming die plates has an outflow edge peripheral to the plate which will define a spinneret orifice through which a fiber forming material flows, which is in fluid communication with said central opening, and which will allow the flow of said fiber forming material along a radial path through which fibers can be extruded, and wherein said fiber forming die plates have fluid distribution openings which are in fluid communication and can form vertical fluid passages; wherein at least one of the fiberizing fluid die plates has an outflow edge peripheral to the plate which will define an opening and allow for the flow of an additional fiber forming material or a fiberizing fluid through said opening, and wherein said fiberizing fluid die plates have fluid distribution openings which are in fluid communication and can form vertical fluid passages; wherein the fiber forming die plates have radial openings to facilitate the passage of the fiber forming material to the orifice; wherein the fiberizing fluid die plates have radial openings to facilitate the passage of the additional fiber forming material or fiberizing fluid through the die; wherein the end plates have openings which are in fluid communication with the additional fiber forming material or fiberizing fluid, and which in combination with the openings in said die plates form vertical fluid passages, and facilitate the distribution of the additional fiber forming material or fiberizing fluid; wherein said enclosure plates bring said stack of plates together and have fluid distribution channels which are in fluid communication with said vertical fluid passages and facilitate the distribution of said fiber forming material or said additional fiber forming material or fiberizing fluid; wherein said die plates, end plates, and enclosure plates have openings for a means for bringing and securing said stack of plates together, wherein said openings can serve as said vertical fluid passages, and wherein said stack of plates can be secured using said vertical passages; and whereby the fiber forming material flowing from the spinneret orifice will form fibers which will be engaged by the additional fiber forming material or fiberizing fluid to shape said fibers.
