The invention relates to glass strands intended for the reinforcement of polymer materials which are coated with a sizing composition comprising, as adhesive film-forming agents, the blend of at least one polyvinyl acetate and at least one polyvinylpyrrolidone, said at least polyvinyl acetate representing 70 to 90% by weight of the solid matter of the size. The glass strands obtained are used as reinforcements in the manufacture of molded parts having a thermosetting matrix obtained by the technique of spray-up molding of said strands and resin, especially by LFI (Long Fiber Injection) molding.
