A fabric, in particular for a paper making machine, includes a plurality of helically wound coil members arranged side by side with respect to each other in an intermeshing manner, such that connecting channels are formed by adjacent intermeshing coil members, a hinge member being introduced into and extending along each connecting channel for interconnecting adjacent coil members, a stuffer channel being formed within each coil member extending along and between two connecting channels associated to a respective coil member, at least a part of the stuffer channels being filled with stuffer members extending longitudinally within the stuffer channels, a stuffer material being provided at least in regions of the fabric for filling spaces formed within the fabric between the coil members, the hinge members and the stuffer members.
摘要:
A method of forming a structured fibrous web including the steps of supplying a fiber slurry to a nip, the nip being formed by a structured fabric and a forming fabric; dewatering the fiber slurry through the forming fabric to create a web; retaining the web with the structured fabric through at least one dewatering process, the forming fabric including a woven fabric having a paper side and a roll side, the paper side having a paper side surface and said roll side having a roll side surface; and providing a polymer material deposit extending above the paper side surface, the polymer material deposit having at least one of a random pattern, a random motif, a pseudo-random pattern, a pseudo-random motif, a predetermined pattern and a predetermined motif.
摘要:
A fabric for an advanced dewatering system having a woven fabric, the woven fabric having a paper side and a roll side, the paper side having a paper side surface and the roll side having a roll side surface and a polymer material. The polymer material is deposited onto the fabric and extends above the paper side surface. The polymer material has at least one of a random pattern, a random motif, a pseudo-random pattern, a pseudo-random motif, a predetermined pattern, and a predetermined motif.
摘要:
A fabric comprising a plurality of coiled yarns arranged in side-by-side intermeshing relationship and having elongated pintles extending through intermeshed portions of the yarn. Elongated stuffer elements extend through central portion of each of the coils in between adjacent pintles. The stuffer elements respond to a given input after insertion to expand and fill the central portions of each of the coils. The input may be temperature, light, sound, chemical and tension. In one form, the stuffer elements formed from auxetic material which is placed in tension, after insertion, to cause the stuffer elements to expand and reduce the permeability of the fabric.
摘要:
The invention relates to a belt for a machine for the production of web material, especially paper or cardboard, including a carrying structure and a pattern of wear-resistant material on at least one side of the carrying structure. The invention further relates to a machine for the production of a fibrous web in which the inventive belt is utilized.
摘要:
A method to produce a press felt for a fiber web producing and/or processing machine, including the steps of a) providing a load bearing base structure, which is, for example, produced of yarns, b) providing a first and a second non-woven fiber layer, c) imprinting a polymer material pattern onto the first or second non-woven fiber layer so that the polymer material pattern partially covers the layer, d) arranging the first non-woven fiber layer on one side of the base structure and e) arranging the second non-woven fiber layer on the first non-woven fiber layer in such a manner that the polymer material pattern is arranged between the two non-woven fiber layers. The present invention further relates to a press felt manufactured according to the method of the present invention.

摘要:
The invention relates to a method for producing a topographical pattern from polymer material on an endless strip with a longitudinal direction and a transverse direction extending perpendicularly thereto, in which method a cylindrical rotary screen is used to apply the polymer material by the screen printing process to a circumferential side of the endless strip to be printed, wherein, when producing the pattern, the rotary screen, rotating repeatedly about its longitudinal axis, rolls on the circumferential side of the endless strip, whereby the pattern is applied to the circumferential side in at least one path running at least once uninterruptedly around the circumferential side in such a way that the beginning and the end of each revolution of the path are arranged along a common straight line, wherein, when rolling, the rotary screen performs N revolutions about its longitudinal axis during each revolution of the path on the circumferential side of the endless strip and N is a positive integer.
