The method comprises the steps of (a) providing a tissue web having a textured top surface lying in a surface plane and a bottom surface lying in a bottom plane wherein there is a z-directional height difference between the surface plane and the bottom plane; (b) conveying the web through a first nip created by a first receiving roll and a pattern roll having a plurality of protuberances forming a design pattern; (c) conforming a portion of the web to the protuberances; and (d) conveying the web into a second nip formed between the pattern roll and a second receiving roll to form a patterned tissue product having a design element corresponding to the plurality of protuberances, the design element lying in a design element plane that is between the surface plane and the bottom plane. The textured surface provides the tissue with an overall background pattern that is typically visually distinct from the design element imparted thereon. The method may further comprise the step of applying a papermaking additive or water to the conformed portion of the web via an applicator roll between step (c) and (d). The pattern roll is generally a hard and non-deformable roll, such as a steel roll. The first receiving roll has a hardness greater than 40 Shore (A), such as from 40 to 100 Shore (A). The second receiving roll may have a smooth or non-smooth surface, and the pressure applied at the second nip is greater than 30 pli, such as from about 50-250 pli.

A method for processing planar material webs made of a fiber-containing material is disclosed. The planar material webs are fed as material web portions or endless material web, for the production of three-dimensional products. Before a material web is pressed for shaping, the material web is preformed three-dimensionally by deforming the material web in at least one direction substantially without stretching or compressing.

The present disclosure relates to a process for the pretreatment of fibrous material in a production process for producing three-dimensional products, to a pretreatment chamber for the pretreatment of fibrous material, and to a fiber molding plant having at least one pretreatment chamber. By pretreating relatively dry fiber material, the shaping step in a manufacturing process can be significantly improved and the choice of product geometries can be increased.

A medium processing apparatus includes a conveyor, a liquid applier, a crimper, a movement assembly, and circuitry. The crimper presses and deforms at least a portion of a plurality of media including a medium to which liquid is applied by the applier, to bind the media. The circuitry causes the assembly to move the applier from a standby position to a position at which the applier faces a liquid application position on the medium before the medium is conveyed to a position at which the liquid is applied; causes the applier to apply the liquid when the medium is conveyed to the position at which the applier faces the liquid application position; causes the assembly to not move the applier to the standby position until application of the liquid to the media ends; and causes the assembly to move the applier to the standby position after the application ends.
