Patent ID: 8778240

Claim:
A device for use in a microfiber and/or nanofiber producing system, the device comprising: a body comprising a first member and a second member, the first member comprising a first member coupling surface, the first member coupling surface comprising one or more grooves extending along the width of the first member coupling surface, the second member comprising a second member coupling surface and a coupling member, the second member coupling surface comprising one or more grooves extending along the width of the second member coupling surface, wherein the body is couplable to a driver through the coupling member; wherein the first member coupling surface is coupled to the second member coupling surface to form the body, wherein the first member and the second member together define an internal cavity of the body; and wherein one or more grooves of the first member coupling member are substantially aligned with one or more grooves of the second member coupling member to form one or more openings extending from the interior cavity to an outer surface of the body; wherein, during use, rotation of the body causes material in the body to be ejected through one or more openings to produce microfibers and/or nanofibers.
