Abstract
Method and arrangement for measuring the position of the end shields of a paper, pulp, or board reel relative to the grab () transporting it, when an end shield is attached to the grab (). During measurement, a detector () is moved along such a curve of a circle that can be assumed to intersect the curve of the circle described by the edge of the object. The angular position of the detector () is measured using the curve of the circle over which it travels and the intersection points (x, z; x, z) of the curve traveled by the detector () and the edge of the object are detected. The location of the center point (x, z) of the object is calculated on the basis of a) the radius of the circle traveled by the detector and the location (xm, zm) of the center point of the circle, b) the location (xt, zt) of the tool point, c) the assumed radius of the object, and d) the locations (x, z; xz) of the detected intersection points. Finally, the position of the center point (x, z) of the object in the set of co-ordinates of the grab is calculated.
