The invention relates to a method for guiding a strip between two opposite coils of a device which comprises a position sensor for determining the position of the strip between the coils. The first coil is impinged upon with a first current and the second coil is impinged upon with a second current if the strip deviates from the desired position.

The invention relates to a strip coating method according to which the strip is guided through two opposite coils of a strip guiding device upstream or downstream of a coating device. Said strip guiding device comprises a position sensor for determining the position of the strip between the coils, current suppliers for the coils and a layer thickness sensor for determining the layer thickness of the coating applied to the strip. The inventive method comprises the following steps: determining a desired layer thickness profile, determining an actual layer thickness profile using the layer thickness sensor, determining a layer thickness control variable by comparing the actual layer thickness profile with the desired layer thickness profile, determining a desired position value for the strip position between the opposite coils using a higher order layer thickness controller whose input signal is the layer thickness control variable, determining an actual position value of the strip between the opposite coils using the position sensor, determining a position control difference by comparing the actual position value with the desired position value, impinging at least one of the coils with current, the current being adjusted in accordance with the output signal of a position controller whose input signal is the position control variable.

The invention relates to a measuring device for determining the strip edge position, the strip width and/or the tensile stress distribution on the width of a strip in a strip treatment installation comprising a deflection roller and a wave transmitter and a wave receiver. Said wave transmitter is oriented in such a manner that waves transmitted in the wave propagation angle thereof strike the peripheral surface of the deflection roller, particularly in the region of the peripheral surface of the deflection roller, in which the edge of the strip deflected by the deflection roller is on the peripheral surface, or that the wave transmitter is oriented in such a manner that waves transmitted in the wave propagation angle thereof in the region of the peripheral surface of the deflection roller, in which the edge of the strip deflected by the deflection roller is on the peripheral surface, lies parallel to the peripheral surface of the deflection roller and at a distance that corresponds to the maximum thickness of the strip. In order to determine tensile stress distribution, sensors are provided in the deflection roller which can measure forces acting in the radial direction of the deflection roller.

Disclosed is a method for assigning the content of a digital image to a class of a classification system. Said method comprises the following steps: - a predetermined number of F numerical shape characteristics ψm are determined; - the value of each shape characteristic of the F numerical shape characteristics determined for the image is compared to the value filed in a table for the respective shape characteristic, values for the individual numerical shape characteristics being allocated to each class in the table; - the class in which the F numerical shape characteristics determined for said image correspond best to the values of the numerical shape characteristics indicated in the table for said class is output as the class into which the image that is to be recognized is classified.
