ABSTRACT:
A glass fiber is drawn through a rotating body of flowable coating material to apply the material thereon and then is further drawn through a throat section of an open ended cage formed by a plurality of wire strands forming a hyperboloid of rotation. As the glass fiber is drawn through the throat section the previously applied flowable material contacts the wire strands causing a vortex of material which centers the fiber in the throat and distributes the material uniformly and concentrically thereon.
