FABRIC FOR PAPERMAKING MACHINE AND ASSOCIATED METHODS Russian patent published in 2014 - IPC D21F1/10 D21F7/08 

FIELD: textiles, paper.

SUBSTANCE: fabric is made with the ability to support a wet paper web for its dewatering, setting the machine direction, and comprises a stable permeable part and two strips spaced apart in transverse direction extending along the fabric in the machine direction, each of which is substantially and consistently airproof, and which restrict the said permeable part enclosed between them. The permeable part is made so that it the wet paper web supported by it extends over its entire width, and the air directed to it can pass through it, but not through the strips, so that the wet paper web, supported only by the permeable part, is dewatered, which width between the impermeable strips thus defines the width of the dewatered wet paper web. At that at least one impermeable strip comprises a self-leveling filler or a coating applied to the fabric so that the impermeable strips have substantially and consistently smooth surfaces and do not retain water.

EFFECT: invention provides protection of the gap of the dryer fabric, as well as ease of setup for different width of the paper web.
