    • 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,所述片材包括至少两个并排放置的纤维层,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 通过在第一圆筒模具或成形器的丝网上过滤纤维的含水悬浮液而产生; 在第二圆筒模具的金属丝上制造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被放置在仍然潮湿的两个层之间; 并且所述两个层被接合在一起,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; 并将由此获得的结构干燥。
