Abstract (en)
The blanket for a papermaking machine has a woven structure with ribbon wefts (2) at the side towards the paper and round we filaments at the machine side. At least two of the round weft filaments (6,7) at the machine side lie against part of the ribbon weft (2) on the paper side, and both weft types are bonded together by at least part of the warp filaments (4,5,12,14). The round weft filaments against the ribbon weft (2) are next to each other. The sum of the diameters of the round weft filaments at the ribbon weft (2) does not exceed the longitudinal width along the length of the blanket (1). The blanket contains no additional wefts apart from the two round weft filaments in contact with the under surface of the ribbon wefts (2). The bonding structure of the woven material, by the warps, is only partially at the paper side, and only with round wefts between those agai the ribbon wefts. At least part of the wefts in the blanket can be ribbons with projecting longitudinal ribs, at the machine sid with a rectangular, trapezoid and/or round cross section. Two or three longitudinal ribs are formed next to each other. The widt the flat wefts, along the longitudinal line of the blanket, is 1-25 mm and preferably 10-15 mm and they have a thickness of 0.2- mm. The warps (4,5,12,14) can have a flat structure with a width on the lateral line of the blanket of 0.5-5.0 mm and with a thickness of 0.2-1.0 mm. The warps (4,5,12,14) bind in only one ribbon weft (2). With at least part of the warps (4,5,12,14), ea neighboring pair of warps (4,5) form warp pairs (3,13,15) in an identical bonding with the wefts (2).
