Abstract (en)
[origin: EP1500619A2] The present invention improve productivity by quickly completing corrections of the amount of yarn rewound which corrections are required to obtain a desired package. The total number of package rotations are acquired for all winding units 1 when the total number of rotations of the winding drum 7 continuously counted from the start of winding reaches a value corresponding to a predetermined package weight during rewinding. Then, on the basis of the total numbers of package rotations, the package weight obtained in each winding unit 1 after the completion of the rewinding is predicted. Then, the amount of yarn rewound is corrected so as to reduce a variation in package weight which may occur during the rewinding process and which may remain after the completion of the rewinding. <IMAGE>
