Abstract: A fabric belt unit for manufacturing corrugated board in a corrugator machine includes a belt (1) joined together at its two ends (2, 3) to form a continuous belt. The fabric belt has an outer paper side (6) as well as an inner driven side (8). The belt ends (2, 3) are reduced thermally in thickness and have a plurality of approximately U-shaped clamps (7) which are connected to each other to form a joint. The U-shaped clamps (7) lie at a distance (a) one next to the other. The distance (u) of the driven side (8) of the belt to the plane (36) of the thickness-reduced belt ends (2, 3) is greater than the distance (v) between the paper side (6) and the plane (46) of the thickness-reduced belt ends (2, 3) in order to obtain a longer service life of the belt.

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.
