    Abstract: A method for producing a paper roll by conveying a first smooth ply between an upper embossing roll with first projections defining a decorative motif, and a glue distribution or cliché roll; maintaining the cliché roll side by side to the upper embossing roll, the first ply interposed between the upper embossing roll and the cliché roll and subjected to incisions and to glue deposits at the first projections on one side of the first ply facing towards the upper embossing roll and on the opposite side of the first ply facing towards the cliché roll; conveying a second ply between the upper embossing roll and a coupling or marriage roll; maintaining the marriage roll side by side to the upper embossing roll by exerting a coupling pressure to perform the final coupling between the first ply and the second ply at the glue deposits forming a multilayer paper.

    Abstract: Anti-falsification paper is provided in which a thread is exposed at window portions provided on the surface of the paper, and which does not produce any cockles even when wound up continuously in a roll and has good appearance in terms of design. This anti-falsification prevention paper is combination paper having at least two paper layers including an outermost layer and an inner layer. Window portions are formed in the outermost layer at intervals in a longitudinal direction of the paper. In the window portions there are formed watermarks of letters or pictures, and a thread inserted between the outermost layer and the other layer is exposed at these window portions. The ratio between the length (X) of the window portions in the longitudinal direction of the paper and the length (Y) in the same direction of non-window portions between the window portions is set at 3:1 to 1:2 to securely prevent the formation of cockles during the winding of paper. This setting of the length ratio of the window portions to the non-window portions also offers desirable effects on the design.

    Abstract translation: PCT No.PCT / JP97 / 00719 Sec。 371日期：1997年11月3日 102（e）日期1997年11月3日PCT 1997年3月7日PCT公布。 公开号WO97 / 34048 PCT 日期1997年9月18日提供了一种防伪纸，其中，在设置在纸表面上的窗口部分处露出螺纹，即使连续卷绕在卷筒上也不产生任何鸟鸣，并且具有良好的外观 设计。 这种防伪防伪纸是具有至少两个包括最外层和内层的纸层的组合纸。 窗口部分在纸的纵向上以间隔形成在最外层中。 在窗口部分中形成有字母或图片的水印，并且在这些窗口部分露出插入在最外层和另一层之间的线。 纸张长度方向上的窗口部分的长度（X）与窗口部分之间的非窗户部分的相同方向上的长度（Y）之间的比率被设定为3:1-1:2 防止在卷纸时形成蛤蜊。 窗口部分与非窗口部分的长度比的设置也为设计提供了期望的效果。
