Abstract: An infrared radiator for the heat treatment of a material web has an incandescent body with a flow-receiving surface that is subjected to a flow of a gas-air mixture supplied to the infrared radiator and heated by combustion of the gas-air mixture. The incandescent body is manufactured as a sheet material formed of a multiplicity of threads and connecting elements that at least indirectly connect the threads to one another. The connecting elements at least partially engage around the threads and thus connect them at least indirectly to one another. The connecting elements are configured in such a way that they may be detached from the connection with the threads, preferably by hand, while breaking up the sheet material.

Abstract: An infrared radiator for the heat treatment of a material web has an incandescent body, which is flowed along a flow-receiving surface by a gas-air mixture supplied to the infrared radiator and heated by combustion of the gas-air mixture. The incandescent body has a surface with which the gas-air mixture or combustion products thereof come into contact. A ratio of the surface area of the incandescent body to the surface area of the flow-receiving surface of the incandescent body is greater than two.

Abstract: An infrared radiator for the heat treatment of a material web includes an incandescent body with a flow-receiving surface to be impinged by a gas-air mixture that is supplied to the infrared radiator and to be heated by combustion of the gas-air mixture. The incandescent body is manufactured as a sheet material that is formed of a multiplicity of threads. The sheet material is manufactured by primary forming.

Abstract: A sheath for a pressing device, the sheath having a cylindrical circumferential face having a circumferential face radius and an annular bearing resiliently mounted to at least one axial end of the sheath in a spring elastic manner. The annular bearing has a smaller radius than the circumferential face radius. Additionally, the sheath has a bellows-shaped transition region extending at the at least one axial end of the sheath from the cylindrical circumferential face to the annular bearing.
