Abstract
Glass fibers are projected along an oscillating trajectory onto a travelling conveyer to form a glass fiber mat. The trajectory is made to oscillate by stripping glass fibers from a pulling wheel by means of a stripping edge, such as a tight wire, which is oscillated arcuately immediately adjacent the surface of the pulling wheel. The stripping means is oscillated at a greater angular velocity where the trajectory makes a greater angle with the conveye=r in order that the impingement point of the trajectory upon the conveyer travel at a substantially uniform velocity across the conveyer so that a mat of uniform density is fabricated.
