摘要: A covering for a machine for producing or processing a fibrous web, in particular a paper or tissue web. The covering includes a basic covering which has a web-contacting upper side and an underside, and a plurality of polymer elements. The polymer elements are welded onto the upper side and at least some of the polymer elements are in the form of yarn-shaped and/or tape-shaped polymer elements.

摘要: A process for foam forming webs is disclosed. A foamed suspension of fibers is fed into a mixing chamber and then directed through a narrow constriction where the velocity of the foamed suspension of fibers is increased. From the narrow constriction, the foamed suspension of fibers enters a forming chamber which causes the foamed suspension of fibers to rapidly decrease in velocity. In one embodiment, for example, the foamed suspension of fibers undergoes a hydraulic jump resulting in significant fiber reorientation. Through the process, fiber orientation can be controlled. For example, webs can be produced that have comparable fiber orientation in the machine direction in comparison to the cross-machine direction.

摘要: A fibrous structure. The structure may include a plurality of continuous or semi-continuous knuckles extending from portions of the surface of the fibrous structure in a parallel path, wherein the plurality of knuckles may be separated by adjacent continuous or semi-continuous pillows. Each knuckle may comprise a plurality of discrete pillows, the plurality of discrete pillows may be arranged in a spaced configuration along the path of each knuckle; alternatively, each pillow may comprise a plurality of discrete knuckles, the plurality of discrete knuckles may be arranged in a spaced configuration along the path of each pillow.

摘要: The invention concerns an insulation material (10) comprising a wood-derived material (11) and a fire retardant (13). The wood-derived material is in the insulation material as a non-separated fiber fraction (14) and as a separated fiber fraction (15) and the insulation material is a combination of said fractions with the fire retardant without separate polymer components (28). In addition, it is also an object of the invention to provide an insulation element, a layer structure, a construction and a method of producing an insulation material.
