Soft, durable and bulky tissue products comprising non-wood fibers and more particularly high yield hesperaloe pulp fibers are disclosed. The tissue products preferably comprise at least about 5 percent, by weight of the product, high yield hesperaloe pulp fiber and have relatively modest tensile strengths, such as a geometric mean tensile (GMT) greater than about 1,000 g/3″, and improved durability and cross-machine direction (CD) properties, such as a CD Stretch greater than about 10 percent. Additionally, at the foregoing tensile strengths the products are not overly stiff. For example the tissue products may have a Stiffness Index less than about 10.0.

A method for a treatment of a product web which is transported in an advance direction includes guiding the product web through a treatment gap which is formed by a first treatment roll being arranged in a first working position and a contour tool, providing a second roll, moving the second roll into a second working position in which the second roll forms a second treatment gap with the counter tool, and moving the first treatment roll into a first parked position in which the first treatment roll does not form a treatment gap with the counter tool.

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 calender includes a rotatable roller, and a belt, co-acting with the roller with a determined belt pressure. At least one material for feeding through the calender is situated between the roller and the belt for a determined contact time during throughfeed through the calender. The calender also includes heating means for heating the fluid and/or the roller, control means for controlling the heating means and/or the belt pressure and/or the contact time, and flow influencing means for initiating and/or influencing a flow of the fluid in the internal space. The control means are configured to control the flow influencing means and thereby the flow of the fluid in the internal space in freely settable manner. A set with a plurality of such calenders and a method for controlling such a calender.

A nonwoven web is made by first depositing fibers as a nonwoven web in a deposition area, then conveying the web away from the deposition area in a web-travel direction, preconsolidating the web in the path, and passing the preconsolidated web between a pair of rollers that compress and final consolidate the preconsolidated web, One of the rollers is separated from the web such that final consolidation of the web at a starting level is stopped and at the same time or immediately beforehand upstream preconsolidation of the web increased. After separating the one roller from the web, another roller is engaged with the web at the consolidation station and then final consolidation is recommenced, whereupon upstream preconsolidation of the web is reduced back to the starting level.

A cooler (144) providing gas blows and comprising at least one cooler module having at least one cooler module (41, 42, 43, 44) of the cooler (144) is curved to provide a gas turn module for turning run of the fiber web (W) from its main running direction 80-190°. The cooler (144) includes moisturizing at least one surface of the fiber web. Having a blowing zone (45, 46, 53) in which gas is blown toward a surface of the fiber web and that the cooler comprises at least one suction zone (51), in which the fiber web evaporated moisture is drawn away from the proximity of a surface of the fiber web. There are cooler modules on both sides of the fiber web. The cooler has a gas turn module located inside a curved fiber web run, which provides gas blows toward the curved fiber web during the run.
