摘要： The invention relates to a slitter-winder for fiber webs, which comprises an unwinding section (10), a slitting section (20) and a winding section (30). The slitter-winder is configured to unwind, slit and wind a thick fiber web to customer rolls (33). The thick fiber web has basic weight of at least 200 g/m2.The unwinding section (10) of the slitter-winder comprises a first unwinder (11) and a second unwinder (12) for unwinding the thick fiber web of from a parent roll comprising full-width thick fiber web (W11, W12), and a joining device (16, 17) for joining a beginning end of a thick fiber web (W11) coming from a parent roll in the first unwinder to an end of a thick fiber web (W12) coming from a parent roll in the second unwinder by forming a joint (J), and the winding section (30) of the slitter-winder comprises a cutting device (35) for cutting and removing part/-s of the thick fiber web comprising the joint (J) from the winding section (30).
