    • A device for checking the coating of anodized light-metal parts (e.g. Aluminum), in particular by TSA anodization, is described. The device has two contact electrodes on respective resilient probes, placed onto the surface of the component to be tested under a predefined contact pressure; an enabling device coupled to the probes that generates an enable signal when the predefined contact pressure is reached; and a conductivity measuring device coupled to the contact electrodes that measures the conductivity of the surface of the component under test.The conductivity measuring device is coupled to the enabling device to detect the enable signal. When the enable signal is detected, the conductivity measuring device measures the surface conductivity of the component under test between the contact electrodes and generates an output signal indicating the measured conductivity. The device distinguishes between a measured low conductivity value, signifying a correct coating, and a measured high conductivity value, signifying a lack of the coating.

    • A device for checking the coating of light-metal parts, in particular aluminum components, which have been coated by anodization, in particular by TSA anodization, is described. The device has two contact electrodes, which are arranged on respective resilient probes and are intended to be placed onto the surface of the component to be tested under a predefined contact pressure, as well as an enabling device, which is coupled to the probes and generates an enable signal when the predefined contact pressure is reached, and a conductivity measuring device which is coupled to the contact electrodes in order to measure the conductivity of the surface of the component to be tested, is coupled to the enabling device in order to pick up the enable signal, measures the conductivity of the surface of the component to be tested between the contact electrodes and, when the enable signal is present, generates an output signal which indicates the measured conductivity and distinguishes at least between a measured low conductivity value, which signifies a correct coating, and a measured high conductivity value, which signifies a lack of the coating.

    • In a group of rolls for a calender for processing material webs, comprising at least two rolls each having a roll body made of a cast or forged iron material, at least one of the roll bodies consists of chilled cast iron or shell-chilled cast iron. One or more rolls may have a cover of a resilient material, such as a polymeric plastic. Although it is possible for the outer diameters of the rolls to differ, the sag of the rolls when they are supported only in their rolling-contact bearings is substantially equal. In order to produce appropriate rolls, following the essential machining steps of the roll bodies, that is to say, for example, following casting, following preliminary turning, following preliminary boring and, if appropriate, following the introduction of peripheral bores, the actual mean modulus of elasticity of the entire roll body is measured and, as a function of this, in particular the inner diameters of the central bores are produced. In addition, methods for influencing the sag of the rolls in a deliberate way, by selecting appropriate materials, the relationships of material structures in the roll body or by means of the deliberate introduction of ballast into the central bore or else into separate peripheral bores in the roll bodies, are described.
    • 在用于加工材料网的压延机的一组辊中，包括至少两个辊，每个辊具有由铸造或锻造的铁材料制成的辊体，至少一个辊体由冷铸铁或壳冷铸铁 。 一个或多个辊可以具有弹性材料的盖，例如聚合物塑料。 虽然辊子的外径可能不同，但是当轧辊仅在其滚动接触轴承中被支撑时，辊的下垂基本相等。 为了生产适当的轧辊，按照辊体的基本加工步骤，即例如在铸造之后，进行初步转弯之后，进行预先钻孔，并且如果合适的话，在引入外围孔之后，实际平均值 测量整个辊体的弹性模量，并且作为其特征，特别地产生中心孔的内径。 另外，通过选择合适的材料，选择合适的材料，在辊体中的材料结构的关系或通过有意将镇流器引入到中心孔中或者分别进入分离的外围孔中的方式来影响辊的凹陷的方法 描述了辊体。
