PAPER-MAKING MACHINE Russian patent published in 2011 - IPC D21F1/00 D21F3/02 D21F11/14 

FIELD: textile, paper.

SUBSTANCE: paper-making machine for drying of fibrous web comprises at least one station, where the fibrous web contains low moisture content. The station contains a permeable cloth, on which the web is transported through a drying machine. The permeable dehydration cloth contacting with the web and directed above the drying machine. The mechanism for application of pressure to the permeable cloth, web and dehydration cloth in the drying machine. Fabric of the shaping net for transfer of the fibrous web to the place in front of the specified station, contains multiple weft or warp threads at the side that faces the web, which are woven to form fabric that contacts with the fibrous web. Multiple weft and warp threads at the machine side woven to form fabric facing machine components in the specified fabric of the forming net. Multiple weft threads of the fabric at the machine side or at the side facing the web woven with multiple warp threads of fabric at the other side, facing the web, or the machine side, to form a multi-layer fabric of the shaping net, having considerable permeability. At the same time each of multiple warp threads is pulled above multiple weft threads of fabric at the other fabric facing the web, or the machine side until it returns into the fabric at the machine side or in the fabric facing the web.

EFFECT: invention provides for development of a shaping net that has higher stability along width and differing by a very good property for drainage and fibre retention.
