PCT No. PCT/FR96/01988 Sec. 371 Date Dec. 29, 1997 Sec. 102(e) Date Dec. 29, 1997 PCT Filed Dec. 12, 1996 PCT Pub. No. WO97/21861 PCT Pub. Date Jun. 19, 1997The subject of the invention is a process for manufacturing a glass strand mat, in which a binder is deposited continuously on a wad of glass strands. The strands are distributed on a moving conveyor, and then the wad is subjected to an oven treatment and possibly to calendering. The process consists of depositing on the wad of strands a liquid binder whose viscosity during deposition is less than approximately 40 millipascal seconds, the binder being formed by an aqueous solution of polyvinyl alcohol(s).
