ABSTRACT:
A method for winding a paper web in which the paper web is unwound from a paper reel and passed through a slitting station of a slitter-winder in which it is slit longitudinally into component webs by blades, and the component webs are further wound into component rolls. A portion of the ends of the slit component webs are cut off in a cutter device to provide them with predetermined measures, i.e., a predetermined initial length, before the component webs are passed into the winding stations. The winding device in winding of a paper web includes an unwind station and a slitter-winder which includes a slitting station, a cutter device, and the winding stations for component rolls. The cutter device of the slitter-winder includes an arrangement for cutting the component webs to provide the predetermined lengths therefor.
