ABSTRACT:
Textile length multifilament bundles of coated and bonded glass fibers are fed into the fiber inlet of a momentum exchange aspirator having a high pressure propelling air source inlet providing propelling air at a velocity generally equal to the velocity of sound to cause flow of air to carry the bundles into the aspirator fiber inlet and produce a turbulent flow zone which destroys the interfiber bonds, without destroying the protective coating on the fibers and with minimum fiber breakage, to form a high velocity stream of discretely separated textile length coated glass fibers at the aspirator outlet.
