Abstract: A method for determining the rolling or guiding gap of the roll stands or guide stands in a multi-stand rolling mill positions a comparison scale at at least one stand, preferably at the first and the last stand, and subsequently the rolling or guiding gap of the respective stand is determined. In this method, a camera is arranged at one of the input or output sides and a transmitter for a reference device, a reference transducer and/or a reference scale is arranged at the other of the input or output sides before the comparison scale is positioned, such that adjustment operations at the camera can subsequently be avoided.

Abstract: An elongated workpiece is treated, e.g. rolled, in a production system where treatment devices move the workpiece longitudinally in a horizontal travel direction and at a generally constant travel speed along a horizontal longitudinal path and a control computer is connected to the treatment devices. Straightness of the workpiece is measured by gripping the workpiece at a pair of longitudinally spaced supports, applying tension to a longitudinally extending horizontal portion of the workpiece between the supports, and continuously moving the workpiece in the travel direction at the travel speed with a lower surface of the portion substantially unsupported. At least periodically a vertical spacing is measured between the portion and a straight longitudinal reference line extending in the direction between the supports parallel to the workpiece at the supports. The vertical-spacing measurement are fed to the computer for use controlling the devices.
