ABSTRACT:
A method for change a reel in a paper winding machine which has at least one carrier roll. The paper web (3) is fed to the carrier roll (1). It wraps around a portion of the circumference of the carrier roll and is wound onto a reel (3.1). Shortly before reaching a desired reel diameter, the machine speed (V) is reduced to a creep speed (k). Subsequently, a weakened line (8) running transversely across is formed on the web and, upstream of the weakened line, an adhesive is applied, while keeping the relative speeds of the web and the covering surface of the carrier roll (1) equal or close to one another. After the web is adhered to the reel (3.1), the reel is expelled or ejected, as a result of which the web is severed at the weakened line (8).
