Abstract of the Disclosure A method of winding glass is provided in which strands of fiber glass prior to collection on a high speed winder are subjected to a high turbulent fluid passed tangential to the strand in a chamber. The strand prior to treatment with the turbulent fluid is tension reduced. The strand treated in this manner has a false twist imparted thereto as well as a curvilinear wave form. The strand is wound after it leaves the turbulent zone and exhibits a mini-traverse in winding in addition to the normal traverse of strand which occurs as the strand traverses the length of the winder by reciprocation of the winder and/or the zone of turbulence.
