A process for producing sized glass yarns, which entails:a) drawing streams of molten glass from orifices located at a bottom of one or more dies, in a form of one or more fans of continuous filaments,b) assembling the filaments into one or more moving supports,wherein a first stable composition having a viscosity of between 0.5 and 250 cP is deposited onto the surface of the continuous filaments, and a second stable composition, supplied separately from the first and having a viscosity of between 0.5 and 300 cP, is deposited onto the surface of the filaments of the yarns, at the earliest during deposition of the first composition and at the latest during collection of the years, the difference in viscosity between the two compositions deposited being less than 150 cP, the mixture of the deposited compositions functioning as a sizing composition and being polymerizable at room temperature. |
