Abstract
A measuring method and a device are adapted for the positioning of a wheel for mash seam resistance welding in the butt-joining of steel strips on continuous processing lines. A rotary roller which is fastened to a movable frame is positioned in a measuring position that is vertically below a reference wheel. The reference wheel is lowered vertically to come into contact and bear on the rotary roller. A distance between an index on a measuring arm of the frame and an articulated column is repeatedly measured during the continuous lowering movement of the roller. The distance is compared with a distance threshold for each of the repeated measurements until the wheel reaches a first operating position where the distance equals a predefined distance threshold factor. The first operating position is recorded as a reference point in a system for the vertical movement of the reference wheel.
