    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: A flexible die is used in an embossing apparatus in which a pair of flexible bases (2a, 2b) are respectively wrapped around a pair of cylindrical rollers disposed opposing each other, and a sheet to be processed (S) is passed through between the pair of rollers, thereby performing embossing. The pair of flexible bases (2a, 2b) are constituted by a female flexible base (2a) and a male flexible base (2b) that are mated with each other, a line-shaped convex portion (3a) corresponding to the contour of an embossing processing pattern is formed in the female flexible base (2a), and the convex portion (3b) is formed in the male flexible base (2b), the convex portion (3b) being fitted within the area encompassed within the line-shaped convex portion (3a) of the female flexible base while leaving an interval from the inner circumferential surface of the line-shaped convex portion (3a). A concave portion (30) is formed in the convex portion (3b).

    Abstract: The invention relates to a method for producing a structured voluminous non-woven fabric, comprising the following steps: producing a spunbonded non-woven fabric consisting of a plurality of monofilaments which are stretched only at 50 to 70% of the maximum possible stretch range to form a fiber skein and subsequent processing the raw non-woven fabric by means of a second pair of rollers (10a, b) with a metal outer jacket to improve the velvet finish. In the second pair of rollers, the positive elements of the positive roller are nops (11) arranged in rows and the surface of the negative roller has lamellas (13) which are arranged in an axial direction and provided with intermediate recesses (14) so that when the rollers roll against each other the lamellas engage in the channels left open by the nops.

    Abstract: An embossing apparatus and method which provides a better embossed appearance and eliminates undesired roughness on the backside of the web material. Two plies are multilevel embossed between rigid engraved rolls and backup rolls, which may be either engraved or smooth. One rigid roll has embossing elements of varying heights and perforation elements, which run in a side-by-side relationship with the corresponding perforation elements on the opposing rigid roll in a nip region of the apparatus. The multiple plies are perforation bonded between the perforation elements, which are preferably the two highest elements, thus reinforcing the other multi-level embossed pattern formed in between the perforation bonds. The embossed patterns impart a quilt-like contoured appearance to the finished product.
