Abstract
A flat glass fiber strand comprises a multiplicity of glass filaments having a non-circular cross-sectional shape with the ratio between its maximum and minimum dimensions being between 1.2:1 and 3:1, and which are gathered in such a manner that one dimension of the cross-section of each extends in parallel with the same dimension of the other filaments. This flat glass fiber strand is manufactured by discharging molten glass under high pressure from a multiplicity of nozzles which are shaped in the form of bores having non-circular cross-sectional shape with the ratio between its maximum and minimum dimensions being between 1.5:1 and 6:1 so as to form a multiplicity of filaments of non-circular cross-sectional shape which are then gathered and wound.
