    • The present invention relates to a process for manufacturing a sheet material comprising at least two fibrous plies juxtaposed one on top of the other, said process comprising the following steps: a first paper ply, which includes at least one elongate region of zero thickness, is produced by filtration of an aqueous suspension of fibres on the wire of a first cylinder mould or of a former; a second paper ply is produced on the wire of a second cylinder mould so as to form at least one recess in the second ply; at least one at least partially transparent element is placed between the two plies that are still wet; and the two plies are joined together so that said at least one recess of the second ply, said at least one at least partially transparent element and said at least one elongate region of zero thickness of the first ply are situated facing one another; and the structure thus obtained is dried.
    • 本发明涉及一种用于制造片材的方法,该片材包括至少两个并列在另一个上的纤维层,所述方法包括以下步骤:包括至少一个零厚度的细长区域的第一纸层是 通过在第一气缸模具或前者的丝线上过滤纤维的水性悬浮液而产生; 在第二圆筒模具的丝线上产生第二纸层,以在第二层中形成至少一个凹部; 至少一个至少部分透明的元件放置在仍然是湿的两层之间; 并且两个层结合在一起,使得所述第二层的所述至少一个凹部,所述至少一个至少部分透明的元件和所述第一层的零厚度的所述至少一个细长区域彼此面对; 将由此获得的结构干燥。

    • The present invention relates to a process for manufacturing a sheet material, comprising at least two fibrous plies juxtaposed one on top of the other, said process comprising the following steps: a first paper ply, which includes at least one elongate region of zero thickness, is produced by filtration of an aqueous suspension of fibres on the wire of a first cylinder mould or of a former, an at least partially transparent element being inserted into said ply during the formation of said ply, and such that said at least transparent element is placed at least in said elongate region of zero thickness; a second paper ply is produced on the wire of a second cylinder mould so as to form at least one recess in said second ply; the two plies are joined together so that at least one recess in the second ply is located facing said at least one elongate region of zero thickness of the first ply comprising an at least partially transparent element; and thus a window is formed and the structure thus obtained is dried.
    • 本发明涉及一种用于制造片材的方法,该方法包括至少两个彼此并置的纤维层片,所述方法包括以下步骤:第一纸层,其包括至少一个零厚度的细长区域, 是通过在第一圆柱模具或成形器的丝网上过滤纤维的含水悬浮液而产生的,至少部分透明的元件在形成所述帘布层期间插入到所述帘布层中,并且使得所述至少透明元件是 至少放置在零厚度的所述细长区域中; 在第二圆筒模具的金属丝上制造第二纸层,以便在所述第二层中形成至少一个凹槽; 所述两个层被接合在一起,使得所述第二层中的至少一个凹部位于所述至少一个包括至少部分透明元件的所述第一层的厚度为零的至少一个细长区域; 并因此形成窗口并且将由此获得的结构干燥。
