摘要：
A method and arrangement for determining the position, relative to the grab (1, 2) transporting them, of the end heads used in packing paper, cellulose, and board rolls, when the end head is attached to the grab (1, 2). When measuring, a detector (7) is transported along such a circular curve, which is assumed to be intersected by the circular curve defined by the edge of the end head. the angle position of the detector (7) on the circular curve of its path is measured and the intersection points (x 1, z l; x2, z2) of the curve travelled by the detector (7) and the edge of the head are detected. The position of the centre point (x0, z0) of the end head is calculated on the basis of a) the radius of the circle travelled by the detector and the position of the centre point (xm, zm) of the circle, b) the position (xt, zt) of the grab's tool point, c) the assumed radius of the end head, and d) the positions (xl, zl; x2, z2), of the detected intersection points. Finally, the position of the centre point (x0, z0) of the end head in the set of co-ordinates of the grab.
