FIELD: textile industry, paper industry. ^ SUBSTANCE: invention relates to paper-pulp industry. Band for shoe press has a number of grooves placing along movement of the band of the mechanism. Each groove has a number of conic flutes. The flute in section is wider at its open upward than a groove, so that the flute runs into contact areas separating neighboring grooves and narrow down till width of groove's bottom. The width of grooves does not exceed depth of the groove. Method of grooves and flutes formation on the surface of the band includes formation of a number of lateral grooves and conic flutes in each groove. The flutes are spaced along each groove, and their centers are placed on the center line of the groove. The flutes are placed with diagonal shift towards the flutes in the neighboring parallel grooves. One or more flutes have an elongate shape stretched along the groove in the direction along movement of the mechanism. ^ EFFECT: enhancement of sheet's dewatering. ^ 7 cl, 5 dwg |
