发明名称 Method in winding of a paper web
摘要 <p>The invention concerns a method in winding of a paper web, in which method the paper web is wound by means of a winder or equivalent and in which method the running speed of the winder is controlled. In the method, the running speed (S) 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 (1,2), i.e. a range of frequency of rotation of the roll in which intensive oscillation occurs, the running speed (S) is lowered quickly so that the speed of rotation of the roll is reduced to a level lower than the lower frequency of the range of oscillation (1,2), and after this the running speed (S) of the winder is increased so that the frequency of rotation (F) of the roll remains invariable until the original running speed (S) of the winder is reached. <IMAGE></p>
