ABSTRACT:
A strand deflector widens the band of fibers from a continuous strand mat pull wheel. The strand deflector defines a plate having a surface with discontinuities such as a pattern of transverse parallel grooves or oblique intersecting grooves. The plate is disposed below the pull wheel and is coupled to and oscillates with the spoked wheel disposed within the pull wheel. The band of fibers impinges upon the plate at a acute angle and is deflected, broadening the width of the band, typically from four to five inches to ten to twenty inches. Higher throughputs and faster line speeds are thus possible for continuous strand mat production lines.
