    Abstract: In the case of a paper bag having a bag wall (1), which separates an inner bag space from an outer space and has at least one visible side (1a) visible from the outer space and an invisible inner side (1b) of a paper layer which is provided with an embossment (9) in the form of at least one symbol, good visibility of the embossment (9) is combined with gentle treatment of the paper fibers of the paper layer by virtue of the fact that the embossment (9) the embossment (9) is embodied in the form of a surface (10) which is elevated with respect to a plane (12) adjacent to the embossment (9) on the visible side (1a) and, corresponding thereto, as a depression which is present with respect to a plane of the inner side adjacent to the embossment (9) on the inner side (1b), that the elevated surface (10) on the visible side (1a) is connected to the plane (12) of the visible side (1a) by means of a connecting wall (11), and that the transition of the elevated surface (10) to the connecting wall (11) and the transition of the connecting wall (11) to the plane (12) of the visible side (1a) have a rounded form, and that the thickness of the paper layer in the region of the embossment (9) is at most 20% smaller than the thickness of the paper layer in the plane (12) adjacent to the embossment (9). An embossment (9) of this type is preferably produced by virtue of the fact that the embossment (9) is formed by guiding the bag wall (1) between an embossing tool (1) and a pressure-exerting tool (3) provided with an elastically compliant surface (5), the embossing tool (2) having the at least one symbol (4) in a depressed formation, such that the paper layer is pressed into the symbol (4) of the embossing tool (1) into the pressure-exerting tool (3) during the embossing operation.

    Abstract: Apparatus for bonding at least two plies of fibrous web, includes: a first roller having an outer periphery, a plurality of embossing protuberances being provided on the outer periphery, such first roller being an embossing roller; and a second roller having an outer periphery and being elastic at least in a radial direction and together with the first roller forming a nip through which the at least two plies are be fed, such second roller being a counter roller or a marrying roller, wherein at least a part of the outer periphery of at least one of the first and the second roller is irregularly rough so that the at least two plies are bonded at discrete locations corresponding to at least some of the embossing protuberances. A multi-ply product including the bonded plies and a corresponding method are also described.

    Abstract: A method for obtaining an incision in an embossing roller using a hob to provide protuberances that are rounded on top and which improve the quality of the embossed material and reduce the wear of the mechanical components of the embossing units. The shape of the protuberances is obtained by machining the cylindrical surface of the roller placed between the tailstocks of the lathe using a hob that has teeth, the profile thereof being complementary to the cross-section of the protuberances. A portion of the hob with the teeth generates the grooves that define the side faces of the protuberances. The grooves between the teeth of the hob have a profile that is curvilinear in a cross-sectional view. With a double pass at two different inclinations of the surface of the roller, the protuberances of FIGS. 5 and 6 are generated.
