CA 2218081

Paper sheets, such as tissue sheets useful for facial tissue, bath tissue and the like, are formed with a decorative pattern (3) imparted to the tissue sheet (1) by the forming fabric (2). The decora-tive pattern is incorporated into the forming fabric by a variety of means, such as stitching, silk screen- ing, printing, weaving, or overlaying a fabric with a decorative pattern onto a conventional forming fabric. The presence of decoratively-shaped areas (3) in the forming fabric (2), which are areas of relatively slow water drainage, cause corresponding areas in the resulting sheet to have a translucent appearance attributable to a relatively lower basis weight and/or different fiber composition. The decorative patterns are preferably formed in the outer or surface layer(s) of the paper sheet.

On forme des feuilles de papier, telles que des feuilles de papier mousseline utiles pour des mouchoirs en papier, du papier hygiénique et analogue, en transmettant un motif (3) décoratif à la feuille (1) de papier mousseline, à l'aide d'une toile de formation (2). On incorpore le motif décoratif à cette toile par divers moyens, tels que des piqûres, la sérigraphie, l'impression, le tissage ou l'incrustation sur une toile de formation classique d'un tissu pourvu d'un motif décoratif. La présence, dans la toile de formation (2), de zones (3) comportant des formes décoratives, lesquelles sont des zones d'évacuation relativement lente de l'eau, fait que les zones correspondantes sur la feuille produite présentent une apparence diaphane que l'on peut attribuer à un grammage relativement inférieur et/ou à une composition de fibres différente. De préférence, on forme ces motifs décoratifs sur la (les) couche(s) extérieure(s) ou de surface de la feuille de papier.
