The invention relates to a drying cylinder which is used to dry a paper, cardboard, tissue or other web of fibrous material in a machine for the production and/or for the transformation thereof. The drying cylinder includes a support body and an external cover layer which is heated by a hot fluid. The thermal flow passing through the external cover layer is increased such that at least one cavity is provided between the support body and the external cover layer through which the fluid flows. The external cover layer is predominately so thin that the ratio formed by the thermal conductivity of the material and the thickness of the external cover layer is greater than a threshold value of 3.2 kW/mK for steel, 30 kW/mK for aluminum, 18 kW/mK for bronze alloys, 3.4 kW/mK for copper and 6.1 kW/mK for magnesium.

Drying cylinder

A support band for a drying arrangement for drying one of a paper, a board, a tissue and a fibrous web in a papermaking machine for at least one of producing and finishing the same, the support band including a water-impermeable sealing layer and at least one water-absorbing storage layer. The at least one water-absorbing storage layer being adjacent to the water-impermeable sealing layer. At least one of the water-impermeable sealing layer or the water-absorbing storage layer being made, at least partially, of a highly thermally conductive material.

Support band

The present invention is a machine for manufacturing a fibrous web from a fibrous suspension, with a sheet forming area that exhibits at least one suction box, which includes a main box with at least one suction box cover that is formed from at least two drainage elements that run laterally to the machine's running direction, border a suction slit, and each has one main body and at least one ceramic. The present invention is identified by the fact that at least; one drainage element and/or one format slide exhibit at least one removable edge piece in which is integrated at least one temperature sensor in order to measure the temperature in the ceramic and/or the temperature at an adhesive point between the ceramic and the associated main body and/or the temperature in the main body. The present invention is furthermore a process and a system for monitoring a drainage element.
