    Abstract: The invention relates to embossing single-ply paper products, for example, paper towels, tissue and napkins, in which an improved embossing arrangement is used which is particularly suitable for paper products which have been processed so as to impart undulations whose axes extend in a principal undulatory direction, typically in the machine direction. The absorbent sheet typically further includes undulations which extend in the cross (transverse direction) of the web such that the absorbent sheet has a biaxially undulatory structure. The undulations may be formed by the use of an undulatory creping blade. Defined parameters accommodate: the distance at which the undulations are spaced, the total surface area of the design (embossing) elements, the width and length of the embossing elements and the aspect ratio of the elements, as well as the angular orientation of the embossing elements with respect to the undulations.

    Abstract: A process for producing a structured, voluminous nonwowen comprises the following steps: (a) a spun nonwoven is produced from a plurality of individual filaments which are stretched and gathered into a skein of fibers; (b) the skein is pressed and not-bonded into a crude nonwoven (12) through a first pair of rollers (9a, b); and (c) the crude nonwoven is further processed through a second pair of rollers (10a, b). The process is characterized in that the individual filaments are initially stretched merely up to a range from 50 to 70% of their maximum possible extension, and in that the crude nonwoven (12) is further processed through a pair of rollers (10a, b) composed of a positive roller (10a) with numerous nops or elevations (11) distributed over the outer surface of the roller and of a negative roller (10) with just as numerous recesses or depressions (12). During rolling, the nops engage the recesses and further stretch the crude non-woven in the area of the roller nops.

    Abstract: High sheet count rolls of spot-embossed, soft bathroom tissue suffer from embossing patterns becoming pressed out by the high winding tension necessary to confine the size of the roll to a diameter of about 5 inches. This size is necessary in order for such high sheet count rolls to fit within the bathroom tissue dispensers found in most households. However, by embossing the tissue between a resilient back-up roll and an engraved embossing roll having short male embossing element heights of only from about 0.005 to about 0.035 inch, the tissue sheet becomes simultaneously calendered, which lowers the sheet caliper (as measured under a compressive load). Because of the resulting lower caliper, the embossed sheet can be wound into the required roll size with less tension on the sheet, such that the embossing pattern for tissue sheets within the roll remains well defined.
