Abstract
The invention relates to a belt for a corrugator machine for making corrugated board (50) wherein at least a middle layer (52) of corrugated material is joined under pressure to cover layers (51, 53) of smooth material to form the corrugated board (50). The belt (1) is made of a fabric of warp fibers and weft fibers (4) and has a paper side facing toward the corrugated board (50) to be manufactured. The paper side (6) lies against the corrugated board (50). A driven side (7) lies facing away from the corrugated board (50). The corrugator machine has a pressure zone (70) which includes a pressure element (71) and a countersupport (73). The corrugated board (50) together with the contact engaging fabric belt (1) passes between the pressure element (71) and the countersupport (73). A drive (61) is provided on the driven side (7) of the belt to generate the tension forces acting in the longitudinal direction of the belt. To reduce the friction loss in the pressure zone, a material is provided on the driven side (7) of the fabric belt (1) for reducing the coefficient of friction of the belt side defining the driven side (7).
