Patent ID: 8079394

Claim:
A belt for a corrugator machine for manufacturing corrugated board having a middle layer made of corrugated material and a covering outer layer made of smooth material which are bonded together under pressure with adhesive, the belt defining a longitudinal direction and having a driven side, and said corrugator machine defining a transport direction and including a pressure element and a countersupport conjointly defining a pressure zone of said corrugator machine, said corrugated board and said belt lying thereon in said longitudinal direction and said belt with said corrugated board passing between said pressure element and said countersupport in said transport direction and said corrugator machine further including a drive unit arranged on said driven side of said belt for developing tension forces acting in said longitudinal direction, the belt comprising: a fabric of warp fibers and weft fibers; said fabric defining a paper side of said belt facing away from said driven side and facing toward said corrugated board to be manufactured; said fabric defining said driven side of said belt with said driven side facing away from said paper side and having a coefficient of friction; a material disposed on said driven side for reducing said coefficient of friction of said driven side; and, said material being applied to said driven side of said belt as a coating and being a lubricating material when said belt is in operation.
