摘要:
Apparatus for and methods of providing a multiplicity of streams of air-entrained fibers. The apparatus is of the type which includes a splitting member having multiple ports disposed in and along the surface of the splitting member; a first conduit duct in communication with a first port for directing a column of air past a first port to cause a portion of the column of fibers to split off and be drawn into the first conduit duct; and a second conduit duct in communication with a second port for directing a column of air past a second port to cause a second portion of the column of fibers to split off and be drawn into the second conduit duct. The method preferably comprises the steps of directing a column of fibers along the splitting member, directing a column of air through the first conduit duct and past the first port so as to draw a portion of the fiber column into the first conduit duct to form a first fiber stream, entraining the first fiber stream in the air, directing the first fiber stream downstream, directing a column of air through a second conduit duct and past a second port so as to draw a portion of the column of fibers into the second conduit duct to form a second fiber stream, entraining the second fiber stream in the air, and directing the second fiber stream downstream.
