Abstract: A drum cover (20a-c) for a drive drum (12) of a corrugated cardboard machine has a textile carrier layer (21), which has a first coating (22) on a first side and a second coating (23) on a second side. The second coating (23) has a glass transition temperature in the range of ?20° C. to 60° C.

Abstract: The invention relates to a fabric belt for the production of a corrugated cardboard web in a corrugated cardboard machine having several warp layers. In at least one edge region of the fabric belt, a surface of its upper warp layer has at least first regions (21) which consist of first yarns, and second regions (22) which consist of second yarns. The first yarns contain 30% b.w. to 100% b.w. aromatic polyamides, 0% b.w. to 70% b.w. aliphatic and/or alicyclic polyamides and 0% b.w. to 5% b.w. other materials. The total of the polyamides and other materials thus gives 100% b.w. The second yarns contain 50% b.w. to 85% b.w. polyester and/or aliphatic polyamides and/or alicyclic polyamides, 15% b.w. to 50% b.w. cellulose and 0% b.w. to 5% b.w. other materials. The total of the polyesters, polyamides, cellulose and other materials gives 100% b.w.

Abstract: A woven belt for a corrugated board machine has a first woven layer made of first warp threads and first weft threads and adapted to take up tensile forces acting on the woven belt. A second woven layer made of second warp threads and second weft threads forms a woven top layer covering the first woven layer. The woven top layer forms a paper side of the woven belt on which paper side corrugated board is supported. The woven top layer is vapor permeable to allow removal of moisture from the paper side. The woven top layer has at least one strip of a friction-increasing material, wherein the at least one strip is narrower in a direction perpendicular to a longitudinal direction of the woven belt than a width of the woven belt.

Abstract: A fabric belt for a corrugated cardboard gluing machine has a first fabric layer for receiving tensile forces. The first fabric layer is made of warp threads and weft threads. A second fabric layer covers the first fabric layer and is made of warp threads and weft threads. The second fabric layer forms an upper paper side of the fabric belt. The first and second fabric layers are interwoven by binding threads. The fabric belt has drainage channels penetrating the fabric belt at least partially, wherein the drainage channels remove moisture from the second fabric layer and the upper paper side.

Abstract: A woven belt for a corrugated cardboard machine has a central woven layer for absorbing tensile stress which consists of first warp and weft threads. The first warp threads cross at least two first weft threads on one side of the central layer before crossing over to the other side. A woven top layer is connected to the upper side and a woven bottom layer is connected to the bottom side of the central layer. The top layer provides a support surface for the cardboard and has second warp and weft threads. The second warp threads cross at least two second weft threads on one side of the top layer before crossing over to the other side. The bottom layer has third warp and weft threads. The third warp threads cross one third weft thread on an inner side of the bottom layer before crossing over to the outer side. The third warp threads cross at least three third weft threads on the outer side of the bottom layer before crossing over to the inner side.

Abstract: A belt connection for conveyor belts, especially for a conveyor belt made of heavy textile fabric and used in an apparatus for manufacturing corrugated paper or cardboard, is provided wherein each one of two belt ends to be connected, at a face thereof, is equipped with a plurality of U-shaped clasps that are arranged adjacent to one another in a direction transverse to a longitudinal center axis of the belts and are spaced at a distance from one another. The clasps are attached to the belt ends in such a manner that, at the respective faces that are opposite each other, a respective receiving channel is formed that extends in a direction transverse to the longitudinal center axis of the belts. The clasps of the opposite faces engage and intermesh in a hinge-type fashion whereby the clasps when engaged in that hinge-type fashion are secured via a connecting rod inserted into the intermeshing receiving channels.
