Abstract

The invention concerns a fibrous material sheet comprising a window formed by transparent film segments (14) having an indented edge forming a closed outline embedded in the fibrous material all along the closed outline, said fibrous material sheet being obtained by implementing a method including steps of immersing partly in a solution of fibers (2) a porous form (1) comprising embossed masks (13), depositing successively on the embossed masks film segments (14) having an edge forming an indented closed outline (14) overlapping the masks, and fashioning a fibrous layer (10) until the indented edges of the film segments (14) are embedded in the fibrous layer.
