Abstract
An apparatus for forming a non-woven mat of nanofibers by using a pressurized gas stream includes paralell, spaced apart, first, second, and third members, each having a supply end and an opposing exit end. The second member is located apart from and adjacent to the first member. The exit end of the second member extends beyond the exit end of the first member. The first and second members define a first supply slit. The third member is located apart from and adjacent to the first member on the opposite side of the first member from the second member. The first and third members define a first gas slit, and the exit ends of the first, second and third members define a gas jet space. A method for forming a non-woven mat of nanofibers utilizes this nozzle.
