A machine for producing a fibrous web, such as a tissue web, has pressing device with a pressing element and a counter-element with a closed surface for forming a pressure nip. A water-absorbing belt with a web side and an opposite pressing element side is guided together with the fibrous web through the pressure nip and the fibrous web is separated at the end of the pressure nip from the web side of the water-absorbing belt and runs further with the counter-element. The water-absorbing belt has at least a first ply and a second ply, and, as viewed in the thickness direction of the water-absorbing belt, a layer in or on the belt half which faces the pressing element, which layer has a higher specific throughflow resistance than the first ply and/or the second ply.

A method of forming a fibrous web on a papermaking machine including the steps of depositing a dilute fiber slurry out of a headbox to a forming area comprising a forming surface made up of a structured fabric, wherein the structured fabric is supported by a breast roll and a forming roll, and the forming area is devoid of any additional fabrics or belts other than the structured fabric, draining the dilute fiber slurry through the structured fabric, and drying the fiber slurry.

A papermaking belt in which changes in surface properties of the resin layer upon use is suppressed, and a method for making the papermaking belt. Provided is a papermaking belt for use in a papermaking machine, including at least one resin layer including a resin, wherein the surface roughness after contacting the surface of the resin layer with a metal plate having a surface roughness equal to or less than 0.10 μm at a pressure of 100±3 kg/cm.sup.2 for 20 hours in warm water bathing at 70±5° C. is equal to or higher than 40% relative to the surface roughness of the surface of the resin layer in a wet state before the contact.

A shoe press has a shoe on which a radial inner surface of a press jacket slides. In a method of operating the shoe press, lubricating fluid is introduced between the shoe and the press jacket for lubricating purposes. The press jacket has at least one polymer layer into which a reinforcing structure is integrated, the reinforcing structure including at least one reinforcing thread. The lubricating fluid, the at least one polymer layer, and/or the at least one reinforcing thread is/are designed such that the lubricating fluid reaches the at least one reinforcing thread of the reinforcing structure and produces a color change in same in the event the polymer layer breaks. There is also described a shoe press, the inclusion of a press jacket in such a shoe press, and a machine with such a shoe press.

A device for micro-embossing paper includes at least one micro-embossing unit to micro-emboss a wet paper ply. The micro-embossing unit includes a micro-embossing cylinder and a counter cylinder facing the micro-embossing cylinder at an embossing area where the wet paper ply is subjected to micro-embossing, and a heater to dry the wet paper ply. The micro-embossing cylinder includes a side surface partially wrapped by the wet paper ply. The heater heats at least one portion of the side surface partially wrapped by the wet paper ply to dry the wet paper ply.

A sheet producing method includes a web forming step of forming a web by accumulating fiber in a dry system, a water providing step of providing the web with water, and a compression-heating step of compressing and simultaneously externally heating the web provided with water, wherein a water content of the web provided with water in the water providing step is 12% by mass or more, and a compression degree of the web between before and after the compression-heating step is 1/7 or less.

A shoe press belt for use in a papermaking machine including at least one resin layer, where the resin layer contains a polyurethane resin formed by curing an urethane prepolymer having an isocyanate group with a curing agent having an active hydrogen group, where the urethane prepolymer is obtained by reacting a polyisocyanate compound containing 4,4′-methylene bis(phenylisocyanate) with a polyol compound containing polytetramethylene ether glycol, and the curing agent contains polycarbonate diol(s).

A machine or apparatus for producing structured tissue or towel using a press section.

The present invention relates to a method for dewatering a web comprising microfibrillated cellulose, wherein the method comprises the steps of: providing a suspension comprising between 50 weight-% to 100 weight-% of microfibrillated cellulose based on total dry weight, forming a fibrous web of said suspension on a support wherein said web has a dry content of 1-25% by weight, applying a dewatering felt into direct contact with the fibrous web, conducting said fibrous web, arranged between said dewatering felt and said substrate, through a pressing equipment. The invention further relates to a film produced from said method.
