Abstract
A method for winding a paper web in which the paper web is wound by a winder or equivalent winding apparatus onto a roll and the running speed of the winder is controlled based on the frequency of rotation of the roll so that when the frequency of rotation of the roll approaches a range of oscillation, i.e., a range of frequency of rotation of the roll in which intensive oscillation occurs, the running speed is lowered quickly so that the frequency of rotation of the roll is reduced to a level lower than the lower frequency of the range of oscillation. Thereafter, the running speed of the winder is increased so that the frequency of rotation of the roll remains substantially constant until, e.g., the running speed of the winder prior to the reduction thereof as the frequency of rotation of the roll approached the range of oscillation is reached.
