Abstract
Method and arrangement for winding a web wherein a roll being formed is supported in an axial direction of the roll by first and second support members placed at sides of the roll. The shape of the end of the roll being formed is measured indirectly or directly, and the relative positions of the support members in relation to one another are regulated based on the measurement. As indirect measurement, it is possible to measure forces in the axial direction of the roll, and as direct measurement, it is possible to measure the side line of a roll end directly by contact measurement or contact-free measurement. Based on the measurements, the relative positions of the support members in relation to one another are regulated such that any defects in the shape at the ends of the roll being formed can be prevented.
