The invention relates to a method and a device for the cutting of end disks for the packing of paper rolls. The invention is characterized in that the diameter of each roll is measured in a measuring unit (1) in a production line, that the number of disk blanks (21, 242) needed for the packing of one paper roll are fed from one or several disk blank magazines (20, 200-203) and placed on and fixed against a cutting table (13, 221), rotatable about a center axis, said table being a part of a cutting unit (10, 205), that a knife (128) of a knife unit (9, 223) in said cutting unit is set at a radial distance from the turning center of the cutting table which corresponds very closely to half of said measured diameter, by translational means (8) for this purpose and on the basis of the values measured by the measuring unit, that disks (21b, 245) are cut from the blanks by rotating the cutting table in relation to the stationary knife, and that the cut disks and the annular excess material are removed from the cutting table separately. |
