The change can be implemented by starting the oscillation or by changing the oscillation in progress. The change can be implemented on the basis of the changes in the transverse profile of the web (W).

Abstract: A wipe product comprises a substrate and functional additive, preferably a high internal phase inverse emulsion, disposed in a discontinuous pattern on the substrate such that the pattern provides areas coated with the emulsion and areas free of the emulsion. When the product is wound into a roll, any two adjacent layers in the roll have their areas coated with the functional additive offset relative to each other. This improves water-retaining characteristics and roll compressibility characteristics of the product. Preferably, the functional additive of one layer is supported by the areas free of the functional additive of the adjacent layer. During the use, upon the application of pressure to the wipe, the emulsion locally expresses water useful for cleaning. The discontinuous pattern of the emulsion provides regions of the substrate which are wetted during use and regions which may remain dry. The wetted regions transfer water to the surface to be cleaned.

Specifically, the pattern is permanently imprinted into the product by compressing and fusing together the bicomponent fibers contained within the lines of the pattern.

Abstract: An apparatus and method for winding tissue webs into a parent roll is disclosed which results in greater uniformity in sheet basis weight, machine direction stretch and bulk when comparing the corresponding sheet properties taken from representative locations throughout the roll. The apparatus and method includes engaging the tissue web against a reel spool with a flexible member such as a transfer belt which traverses an unsupported span between two support rolls. The web is transferred from the transfer belt to the parent roll as the parent roll is urged against the sheet/transfer belt at a point within the unsupported span. The resulting deflection of the transfer belt is detected and, in response, the reel spool position is changed to control the deflection at a desired level. Accordingly, a predetermined light nip pressure can be applied to the roll as the tissue web is wound thereon and large parent rolls of high bulk tissue can be manufactured with desired properties when unwound.

Abstract: The perceived softness of embossed tissue can be increased greatly while avoiding nesting when a particular pattern is embossed into the tissue.

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.

Abstract: An embossed tissue having improved bulk and puffiness while being non-nesting by having a lattice pattern and at least two signature bosses. More particularly, one of the signature bosses is defined by embossments having a lower portion which is continuous and an upper portion which is defined by crenels and merlons.
